ETHYL 2-METHYL-4,4,4-TRIFLUOROACETOACETATE CAS:344-00-3

N-Ethyl 2-methyl-4,4,4-trifluoroacetoacetate (EMTFA) waxaa lagu gartaa qaab-dhismeedkeeda molecular, kaas oo ay ku jiraan koox trifluoromethyl (-CF3) oo ku xiran laf-dhabarta β-keto ester. Qaab-dhismeedkani wuxuu EMTFA siiyaa xasillooni iyo falcelin muhiim ah, taasoo ka dhigaysa mid ku habboon codsiyo kiimiko oo ballaaran. EMTFA caadi ahaan waxay u jirtaa sidii dareere cad oo aan midab lahayn oo leh dhibic karkaraya oo ku dhow 140°C waxayna muujinaysaa milmi wanaagsan oo ku jira dareerayaasha organic-ga caadiga ah sida acetone iyo ethyl acetate. Xasilloonideeda xaalado kala duwan waxay u oggolaanaysaa isticmaalkeeda wax ku oolka ah ee cilmi-baarista shaybaarka iyo hababka warshadaha labadaba. Isticmaalka Isku-darka Dabiiciga ah: EMTFA waxay u adeegtaa sidii baloog dhisme oo muhiim ah oo ku jira isku-darka organic-ga, gaar ahaan soo bandhigida qaababka trifluoromethylated ee molecules-ka organic-ga. Awooddani waa lama huraan u ah horumarinta daawooyinka, beeraha, iyo kiimikooyinka gaarka ah oo leh firfircooni bayooloji iyo xasillooni kiimiko ah. Kiimikada Daawada: Codsiyada dawooyinka, EMTFA waxaa loo isticmaalaa sidii horudhac ku saabsan isku-darka maaddooyinka dawooyinka firfircoon (APIs) sababtoo ah awooddeeda ay ku bixin karto sifooyinka daawada ee la rabo. Waxay door muhiim ah ka ciyaartaa kiimikada daawada iyadoo awood u siineysa wax ka beddelka molecules-ka daawada si loo xoojiyo waxtarka loona yareeyo u nuglaanshaha dheef-shiid kiimikaadka. Kiimikooyinka Gaarka ah: EMTFA waxay ku heshaa adeegsiga soo saarista kiimikooyinka gaarka ah sida sunta cayayaanka, sunta cayayaanka, iyo dhexdhexaadiyeyaasha isku dhafan ee loo isticmaalo isku-darka kiimikooyinka beeraha iyo kiimikooyinka wanaagsan. Kala duwanaanshaheeda isbeddellada kiimikada waxay ka dhigaysaa mid qiimo leh qaacidooyinka halkaas oo loo baahan yahay xakameyn sax ah oo ku saabsan qaab-dhismeedka molecular iyo shaqeynta. Isku-darka Ethyl 2-methyl-4,4,4-trifluoroacetoacetate waxaa lagu sameeyaa iyada oo loo marayo geeddi-socod badan oo ka bilaabma fal-celinta isku-darka Claisen ee ethyl trifluoroacetate oo leh methyl acetate, oo ay ku xigto esterification xaaladaha la xakameeyey. Falcelintu waxay caadi ahaan ku socotaa joogitaanka kiciyaha saldhigga ah si loo fududeeyo sameynta ester-ka β-keto. Farsamooyinka nadiifinta sida kala-soocidda ama dib-u-cusboonaysiinta ayaa loo adeegsadaa si loo helo EMTFA oo nadiif ah oo ku habboon codsiyada warshadaha. Jidka isku-darka tooska ah iyo helitaanka agabka bilowga ah waxay gacan ka geystaan ​​​​kharash-oolnimada iyo isticmaalka baahsan ee cilmi-baarista tacliinta iyo hababka warshadaha. Marka la soo koobo, ethyl 2-methyl-4,4,4-trifluoroacetoacetate waa isku-dhisyo badan oo leh codsiyo muhiim ah oo ku saabsan isku-darka dabiiciga ah, kiimikada dawooyinka, iyo soo saarista kiimikooyinka gaarka ah. Sifooyinka kiimikada ee gaarka ah, oo ay ku jiraan xasilloonida, falcelinta, iyo fududaynta isku-darka, waxay u dhigaan inay tahay ciyaaryahan muhiim ah oo ku saabsan horumarinta teknoolojiyada qaybaha kala duwan ee warshadaha iyo cilmiga sayniska.
