ethyl difluoroacetate CAS: 454-31-9

Ethyl difluoroacetate (EDA) yog tus cwj pwm los ntawm nws cov qauv molecular, muaj ib pawg difluoromethyl (-CF2COOEt) txuas nrog ib qho ethyl ester moiety. Cov qauv no muab kev ruaj khov thiab kev ua haujlwm tseem ceeb rau EDA, ua rau nws haum rau ntau yam kev tshuaj lom neeg thiab kev siv. EDA feem ntau muaj nyob rau hauv cov kua ntshiab, tsis muaj xim nrog lub ntsiab lus kub ib puag ncig 100 ° C thiab ua kom pom kev yaj zoo hauv cov kuab tshuaj organic xws li acetone thiab ethyl acetate. Nws qhov kev ruaj khov nyob rau hauv ntau yam mob tso cai rau nws siv tau zoo hauv kev tshawb fawb hauv chaw kuaj mob thiab cov txheej txheem kev lag luam. Siv Organic Synthesis: EDA ua haujlwm ua lub hauv paus tseem ceeb hauv kev tsim cov organic synthesis, tshwj xeeb tshaj yog hauv kev qhia txog difluoromethyl pawg rau hauv cov organic molecules. Lub peev xwm no yog qhov tseem ceeb rau kev tsim cov tshuaj, agrochemicals, thiab cov tshuaj tshwj xeeb nrog kev ua haujlwm ntawm lub cev thiab kev ruaj khov tshuaj. Tshuaj Chemistry: Hauv kev siv tshuaj, EDA yog siv ua ntej hauv kev tsim cov khoom xyaw tshuaj (APIs) vim nws muaj peev xwm muab cov khoom siv tshuaj zoo. Nws ua lub luag haujlwm tseem ceeb hauv kev kho mob los ntawm kev ua kom muaj kev hloov pauv ntawm cov tshuaj molecules kom txhim kho kev ua haujlwm thiab txo qhov kev cuam tshuam ntawm cov metabolism. Cov Tshuaj Tshwj Xeeb: EDA pom daim ntawv thov hauv kev tsim cov tshuaj tshwj xeeb xws li surfactants, plasticizers, thiab cov intermediates nyuaj siv hauv kev tsim cov agrochemicals thiab cov tshuaj zoo. Nws qhov kev hloov pauv hauv kev hloov pauv tshuaj ua rau nws muaj txiaj ntsig zoo hauv cov qauv uas xav tau kev tswj hwm meej ntawm cov qauv molecular thiab kev ua haujlwm. Kev Tsim Khoom Ethyl difluoroacetate yog tsim los ntawm kev sib xyaw esterification ntawm difluoroacetic acid nrog ethanol. Cov txheej txheem no cuam tshuam nrog kev sib xyaw ntawm difluoroacetic acid nrog ethanol nyob rau hauv cov xwm txheej tswj hwm los tsim EDA. Cov tshuaj tiv thaiv feem ntau yog catalyzed los ntawm cov kua qaub lossis cov hauv paus los pab txhawb kev tsim ester bond. Cov txheej txheem purification xws li distillation lossis solvent extraction siv los tau txais EDA hauv kev huv si siab haum rau kev siv hauv kev lag luam. Txoj kev yooj yim synthesis thiab kev muaj cov khoom siv raw pab txhawb rau nws cov nqi-zoo thiab kev siv dav hauv kev tshawb fawb kev kawm thiab cov txheej txheem kev lag luam. Hauv kev xaus, ethyl difluoroacetate yog ib qho tshuaj sib xyaw ua ke nrog cov ntawv thov tseem ceeb hauv kev tsim cov organic, tshuaj lom neeg, thiab kev tsim cov tshuaj tshwj xeeb. Nws cov khoom siv tshuaj lom neeg tshwj xeeb, suav nrog kev ruaj khov, kev ua haujlwm, thiab yooj yim ntawm kev sib xyaw, pab txhawb nws qhov tseem ceeb hauv kev txhim kho cov thev naus laus zis thoob plaws ntau yam kev lag luam thiab kev qhuab qhia txog kev tshawb fawb.
