i-ethyl difluoroacetate CAS:454-31-9

I-Ethyl difluoroacetate (EDA) ibonakaliswa yisakhiwo sayo semolekyuli, equka iqela le-difluoromethyl (-CF2COOEt) elidityaniswe nenxalenye ye-ethyl ester. Esi sakhiwo sinika uzinzo olukhulu kunye nokusebenza kwakhona kwi-EDA, okwenza ukuba ifaneleke kwiindlela ezahlukeneyo zokuphendula kweekhemikhali kunye nokusetyenziswa. I-EDA ihlala ikhona njengolwelo olucacileyo, olungenambala olunendawo yokubila malunga ne-100°C kwaye ibonisa ukunyibilika okuhle kwizinyibilikisi ze-organic ezifana ne-acetone kunye ne-ethyl acetate. Uzinzo lwayo phantsi kweemeko ezahlukeneyo luvumela ukusetyenziswa kwayo ngempumelelo kuphando lwelabhoratri kunye neenkqubo zemizi-mveliso. Ukusetyenziswa kwe-Organic Synthesis: I-EDA isebenza njengebhloko ebalulekileyo yokwakha kwi-organic synthesis, ngakumbi ekungenisweni kwamaqela e-difluoromethyl kwiimolekyuli ze-organic. Olu buchule lubalulekile ekuphuhliseni amayeza, iikhemikhali zezolimo, kunye neekhemikhali ezikhethekileyo ezinemisebenzi yebhayoloji ephuculweyo kunye nokuzinza kweekhemikhali. I-Pharmaceutical Chemistry: Kwizicelo zamayeza, i-EDA isetyenziswa njengesandulela ekuhlanganisweni kwezithako zamayeza ezisebenzayo (ii-API) ngenxa yokukwazi kwayo ukunika iipropati ze-pharmacological ezinqwenelekayo. Idlala indima ebalulekileyo kwikhemistri yezonyango ngokuvumela ukuguqulwa kweemolekyuli zamayeza ukuphucula ukusebenza kakuhle nokunciphisa ukuthambekela kwe-metabolic. Iikhemikhali ezikhethekileyo: I-EDA ifumana ukusetyenziswa ekuvelisweni kweekhemikhali ezikhethekileyo ezifana nee-surfactants, ii-plasticizers, kunye ne-complex intermediates ezisetyenziswa ekuvelisweni kweekhemikhali zezolimo kunye neekhemikhali ezintle. Ukuguquguquka kwayo ekuguqulweni kweekhemikhali kuyenza ibe luncedo kwiifomyula apho kufuneka ulawulo oluchanekileyo kwisakhiwo semolekyuli kunye nokusebenza. Ukwenziwa kwe-Ethyl difluoroacetate kwenziwa nge-esterification reaction ye-difluoroacetic acid ene-ethanol. Le nkqubo ibandakanya ukujiya kwe-difluoroacetic acid ene-ethanol phantsi kweemeko ezilawulwayo ukuze kwenziwe i-EDA. Ukusabela kudla ngokuqhutywa zii-asidi okanye iziseko ukuze kube lula ukwakheka kwe-ester bond. Iindlela zokucoca ezifana ne-distillation okanye i-solvent extraction zisetyenziswa ukuze kufunyanwe i-EDA ngobunyulu obuphezulu obufanelekileyo kwizicelo zoshishino. Indlela ethe ngqo yokwenziwa kunye nokufumaneka kwezinto eziluhlaza kunegalelo ekusebenzeni kwayo kakuhle kweendleko kunye nokusetyenziswa ngokubanzi kuphando lwezemfundo kunye neenkqubo zoshishino. Ngamafutshane, i-ethyl difluoroacetate yikhompawundi eguquguqukayo enezicelo ezibalulekileyo kwi-organic synthesis, i-pharmaceutical chemistry, kunye nemveliso yeekhemikhali ezikhethekileyo. Iimpawu zayo ezikhethekileyo zeekhemikhali, kuquka ukuzinza, ukusabela ngokukhawuleza, kunye nokulula kokwenziwa kwezinto, zinegalelo ekubalulekeni kwayo ekuphuculeni ubuchwepheshe kumacandelo ahlukeneyo emizi-mveliso nakwiinkalo zesayensi.
