Summary in Hungarian A kutatás összefoglalója, célkitűzései szakemberek számára Itt írja le a kutatás fő célkitűzéseit a témában jártas szakember számára. A minket körülvevő világ, a benne lakók és a természeti kincseink védelme egyre inkább felértékelődik. Nem közömbös tehát, hogy a szerves vegyipar milyen mértékben szennyezi a környezetet. Jelen projekt zöldkémiai indíttatású, és szerves kémiai szintézisek környezetbarátabbá tételével foglalkozik. A szűkebb tematika a mikrohullámú (MW) technika alkalmazása szerves foszforkémiai átalakításokban. Egyrészt a MW adta általános előnyöket (gyors, szelektív és hatékony reakciók) szeretnénk kihasználni a kiválasztott reakciókban, másrészt a hagyományos melegítésre nehezen lejátszódó átalakításokat tervezünk megvalósítani MW besugárzás alkalmazásával, harmadrészt katalizátorok elhagyását, ill. katalizátor rendszerek egyszerűsítését célozzuk meg MW körülmények között. Az oldószermentes megvalósítás, ill. az alternatív oldószerek (víz/ionos oldószerek) alkalmazása is vizsgálataink tárgyát képezi. Kiemelt cél a MW szerves kémiai szintézisekben való alkalmazhatóságának feltérképezése, vagyis annak tisztázása, hogy milyen energetika (termodinamika és kinetika) mellett képes a MW besugárzás a szerves kémiai átalakításokat segíteni. Az is egy fontos kérdés, hogy hogyan fejti ki a MW a reakciókra gyakorolt pozitív hatását. Harmadrészt, kihívás számunkra, hogy a hatás értelmezése után azt matematikailag modellezzük.
Mi a kutatás alapkérdése? Ebben a részben írja le röviden, hogy mi a kutatás segítségével megválaszolni kívánt probléma, mi a kutatás kiinduló hipotézise, milyen kérdéseket válaszolnak meg a kísérletek. A kutatás alapkérdése annak tisztázása, hogy az egyes szerves kémiai reakciók esetében milyen előnnyel járhat a mikrohullámú (MW) technika alkalmazása. Másképpen nem, vagy csak nehezen lejátszódó reakciókat tehet lehetővé, vagy csak hatékonyabbá teheti a reakciókat, vagyis gyorsabban, szelektívebben és jobb termeléssel fognak lejátszódni. A MW besugárzás továbbá katalizátorokat válthat ki, vagy katalizátor rendszereket egyszerűsíthet. A kérdéskör tisztázása végülis a szerves vegyipar (finomkémiai ipar, gyógyszeripar és növényvédőszeripar) kihívásaira ad választ, vagyis hogy hogyan lehet környezetbarátabbá tenni bizonyos kémiai átalakításokat. Kérdés továbbá a MW pozitív hatásának értelmezése, ill. a sebességnövekedés ennek megfelelő matematikai modellezése, ami egy teljesen új terület. A MW besugárzás gyorsító hatásának értelmezése jelenleg is az érdeklődés homlokterében áll. Abban már egyetértés van, hogy nincs semmiféle mágikus hatás, hanem valamiféle termikus hatás felelős a MW pozitív hatásáért. Eddig jónéhány folyóiratcikkben és nemzetközi konferencián képviseltük azon nézetünket, hogy a MW gyorsító hatása random lokális túlmelegedésekre vezethető vissza, és szisztematikusan cáfoltuk a „nem-termikus” mágikus magyarázatokat. Elméletünket tovább finomítva továbbra is ezt a küldetést szeretnénk betölteni.
Mi a kutatás jelentősége? Röviden írja le, milyen új perspektívát nyitnak az alapkutatásban az elért eredmények, milyen társadalmi hasznosíthatóságnak teremtik meg a tudományos alapját. Mutassa be, hogy a megpályázott kutatási területen lévő hazai és a nemzetközi versenytársaihoz képest melyek az egyediségei és erősségei a pályázatának! A kutatás jelentősége, hogy feltárja a mikrohullámú (MW) technika alkalmazhatóságát az egyre jelentősebbé váló foszforkémiai diszciplínán belül. Fontos átalakításokat, úgymint észteresítéseket, hidrolíziseket, szubsztitúciókat, addíciókat, kondenzációkat, kapcsolási reakciókat, redukciókat és fragmentációkat vizsgálunk, hogy csak a legfontosabbakat említsük. Várhatóan olyan általánosan, a szerves kémia más területein is hasznosítható ismeretekhez jutunk, amelyeknek hatása lehet a környezetbarát diszciplína fejlődésére, és amelyek hasznosíthatók lehetnek K+F tevékenységek során. Fontos továbbá, hogy értelmezni próbáljuk a MW hatást és megkíséreljük matematikailag modellezni azt. Ez a téma egy nagyon „forró” terület, amivel sok kutató foglalkozik. A lokális túlmelegedéseken alapuló elméletünk finomítása beleillik a MW hatást értelmező legújabb elméletekbe, amelyek termikus hatást tételeznek fel, és elvetik a különféle „nem-termikus” effektusokon alapuló magyarázatokat. Az ilyen és hasonló kutatásokra „vevő” a szerves kémiai társadalom. Kutatásunk során oldószermentes ill. vízben megvalósítható reakciókat is vizsgálunk. A manapság oly divatos ionos folyadékokat nem feltétlenül oldószerként, hanem – egy sokkal realisztikusabb elképzelés szerint – reakciót gyorsító adalékként (katalizátorként) is kipróbálnánk. Továbbá, költséget és környezeti terhet jelentő katalizátor rendszereket és katalizátorokat kívánunk egyszerűsíteni, ill. MW besugárzással kiváltani. A saját kifejlesztett katalizátorok meg hatékony átalakításokat tehetnek lehetővé. Eddigi eredményeinket rangos nemzetközi folyóiratokban sikerült publikálni és konferenciákon is parázs vitákat váltottunk ki. A folytatás is komoly eredményeket és jelentékeny visszhangot ígér.
A kutatás összefoglalója, célkitűzései laikusok számára Ebben a fejezetben írja le a kutatás fő célkitűzéseit alapműveltséggel rendelkező laikusok számára. Ez az összefoglaló a döntéshozók, a média, illetve az érdeklődők tájékoztatása szempontjából különösen fontos az NKFI Hivatal számára. Világszerte terjed a kemofóbia, vagyis a kemikáliák (növényvédőszerek, gyógyszerek, mosóporok, színezékek, stb.) ill. a vegyipar hibáztatása a környezetünk (a talaj, víz és levegő szennyezettség) jelenlegi állapota, valamint a minket körülvevő világot, az élőlényeket és az élővilágot ért káros hatások (pl. globális felmelegedés ill. egyes élőlények kihalása) kapcsán. Nemcsak a tévhiteket kell a helyükre tenni, hanem olyan szerves kémiai átalakításokat kell kidolgozni, amelyek környezetbarátak, vagyis nem járnak káros melléktermékek képződésével és kerülik a veszélyes reagensek és oldószerek alkalmazását. Jelen projektünk ilyen célok megvalósításán kíván fáradozni a szerves kémia egy speciális területén, a szerves foszforkémiában, méghozzá a mindennapjainkból jól ismert mikrohullámú (MW) technika alkalmazásával. Komoly előnyökkel járhat a reakciókat a konyhai mikrohullámú kemencékhez hasonló, de precíziós MW reaktorokban lejátszatni. Ily módon a kémiai átalakulások gyorsabbak és hatékonyabbak lesznek, továbbá a MW besugárzás a reakció lejátszódását elősegítő katalizátorokat válthat ki, vagy egyszerűsíthet. Másfelől arra a kérdésre keressük a választ, hogy hogyan fejti ki a MW a reakciókra gyakorolt pozitív hatását. Az erre vonatkozó nézeteinket az Élet és Tudomány 2013, 22, 691-693 cikkünkben írtuk le közérthető módon. Végezetül a MW hatását modellezni szeretnénk matematikai megközelítéssel. A téma igen érdekes, áttételes hatása lehet a mindennapi életünkre és nemzetközi érdeklődésre tart számot.
| Summary Summary of the research and its aims for experts Describe the major aims of the research for experts. The protection of the world, its inhabitants and our natural treasures has been gradually valorized. The pollution of the environment by the organic chemical industry became a key question. The present project is motivated by environmentally-friendly (“green”) chemistry, as the purpose is to perform reactions under green chemical conditions. The narrower topic is the accomplishment of organophosphorus reactions under microwave (MW) conditions. On the one hand, we should like to make use of the advantages (shorter reaction times, selective and efficient reactions) of the MW technique in frequently applied and more special reactions, on the other hand we wish to promote transformations by MW irradiation that are rather reluctant or resist proceeding on traditional thermal heating. It is also our purpose to substitute catalysts by MW irradiation, or at least simplify catalyst systems under MW conditions. The application of the MW technique is often associated with solvent-free accomplishment, but ionic liquids and water will also be tried out as solvents. It is an important purpose for us to map the applicability of MWs in organic syntheses. In other words, we wish to clarify the relation between the energetics (thermodinamics and kinetics) of the reactions and the efficiency of MW irradiation. We plan to obtain more insights into the scope and limitations of MW-assisted reactions. It is a further challenge to find an explanation for the beneficial effect of MWs that means the refinement of our theory on the role of random local overheating. An additional challenge is to model the beneficial effect of MWs mathematically after the interpretation of the phenomenon.
What is the major research question? Describe here briefly the problem to be solved by the research, the starting hypothesis, and the questions addressed by the experiments. The basic question of this project is to explore the advantages of the application of the microwave (MW) technique during the individual reactions investigated. MW irradiation may promote thermally reluctant reactions, or simply makes the transformations more efficient. In the latter case, the reactions become faster and more selective, giving the products in better yields. Beside this, MW irradiation may substitute catalysts, or may make possible the simplification of catalyst systems. Our project tries to find answers to actual challenges of the organic chemical industry (fine chemical industry, pharmaceutical industry and plant protecting industry), ie., how it is possible to make certain organic chemical transformations more environmentally-friendly. Further questions are the interpretation of the beneficial effect of MWs, and the suitable mathematical modelling of the phenomenon that has never been attempted before. The interpretation of the effect of MWs is in the focus these days, and there seems to be an agreement that thermal effects are responsible for the rate enhancing effect of MW irradiation. The non-thermal effects representing some kind of magic have been rejected. We have published our theory on the beneficial effect of the randomly occurring local overheatings both in articles, and in conferences. We wish to continue spreading the correct views on the MW heating, and it is also our purpose to refine the theory.
What is the significance of the research? Describe the new perspectives opened by the results achieved, including the scientific basics of potential societal applications. Please describe the unique strengths of your proposal in comparison to your domestic and international competitors in the given field. The importance of our research is that it explores the applicability of the microwave (MW) technique in the organophosphorus discipline that becomes more and more important. Among others, important transformations, such as esterifications, hydrolyses, substitutions, additions, condensations, coupling reactions, reductions and fragmentations will be investigated. It can be expected that the results will have an impact on the development of the green chemical field in all segments of organic chemistry, and a part of the results will be utilizable during the R & D activity. It is also important that we try to interpret and model the beneficial effect of MWs. Our project is on a rather “hot” field searched by a lot of scientists. The refinement of our theory based on the enhancing effect of local overheatings fits well the up-to-date explanations assuming thermal effects. The organic chemical “society” is eagerly recipient for any kind of new information on MW chemistry. During our work, solvent-free reactions and the possible use of water as the solvent will also be studied. The – these days – fashionable ionic liquids will not be used only as solvents, but also as additives (catalysts) that is a novel and realistic idea. Moreover, catalyst systems and catalysts meaning costs and environmental burden will be simplified and – if possible – substituted by MW irradiation. The catalysts developed by us may make possible efficient syntheses. Due to the "hotness" of our project, it is probable that we shall be able to continue publishing our results in good international journals.
Summary and aims of the research for the public Describe here the major aims of the research for an audience with average background information. This summary is especially important for NRDI Office in order to inform decision-makers, media, and others. Many of the people believe that the organic chemical industry producing plant protecting agents, pharmaceuticals, washing powders, etc. is to be blame for the pollution of the environment (earth, waters and air). Partially it is true, however, we have to fight against injustic chemofoby. It is also our duty to elaborate environmentally-friendly (“green”) syntheses utilizing reagents and solvents that are not harmful. The present project will contribute to this discipline in the special field of microwave(MW)-assisted organophosphorus chemistry. While the use of MW ovens is common in households, the MW reactors are special equipment in which chemical transformations may be performed. The utilization of MWs is advantageous, as the reactions become faster and more efficient. It is also a challenge to replace or simplify catalysts useful in organic syntheses by MW irradiation. Our special purpose is to provide an explanation for the beneficial effect of MWs, and to elaborate a suitable mathematical model. Our project represents a hot topic, and my have a slight impact on our every day life by enriching the environmentally-friendly approaches.
