1,3-Difluoroacetone CAS:453-14-5

1,3-Difluoroacetone (DFA) ke motsoako o feto-fetohang o nang le thepa e ikhethang ea lik'hemik'hale e etsang hore e be ea bohlokoa lits'ebetsong tse fapaneng tsa indasteri. Thepa ea 1,3-Difluoroacetone e khetholloa ka sebopeho sa eona sa limolek'hule, se kenyeletsang sehlopha sa ketone (-C(=O)-) se nkeloang sebaka ke liathomo tse peli tsa fluorine. Tšobotsi ena ea sebopeho e fana ka karabelo e hlokomelehang le botsitso ho motsoako, e susumetsa ts'ebeliso ea eona tlhahisong ea lintho tse phelang le liketsong tsa lik'hemik'hale. Hangata DFA e teng e le mokelikeli o feto-fetohang o nang le ntlha e belang e ka bang 80°C 'me e bontša ho qhibiliha ho itekanetseng li-solvents tsa polar joalo ka metsi le acetone. Ho tsitsa ha eona ea lik'hemik'hale tlas'a maemo a bonolo ho e etsa hore e lokele ho sebelisoa e le motheo oa kaho tlhahisong ea limolek'hule tse rarahaneng tsa lintho tse phelang. E Sebelisa Ts'ebetso ea Organic: E 'ngoe ea lits'ebetso tsa mantlha tsa 1,3-difluoroacetone e ho tlhahiso ea lintho tse phelang, moo e sebetsang e le karolo ea bohlokoa ea bohareng kapa selelekela. Sehlopha sa eona sa ketone se arabelang se lumella ho kenngoa ha liathomo tsa fluorine ka har'a limolek'hule tsa lintho tse phelang, ho nolofalletsa tlhahiso ea meriana, lik'hemik'hale tsa temo le lik'hemik'hale tse ikhethang tse nang le ts'ebetso e lakatsehang ea fluorine. Sesebediswa sa Khemikhale: DFA e sebediswa e le sesebediswa sa dikhemikhale ditsamaisong tse fapaneng tsa laboratori le tsa indasteri, ho kenyeletswa le phetoho ya dimolekule le tlhahiso ya metswako e nang le fluorine. Bokgoni ba yona ba ho feta diphetohong tsa nucleophilic le dikarabelo tsa ho kolobisa bo atolosa tshebediso ya yona diphetohong tse fapaneng tsa dikhemikhale. Saense ya Thepa: Saenseng ya thepa, DFA e fumana ditshebediso ntshetsopeleng ya thepa e ikgethang le dikobo. Ho arabela ha yona le bokgoni ba yona ba ho susumetsa thepa ya bokahodimo ho etsa hore e lokele ho fetola bokahodimo ba thepa ho ntlafatsa ho tshwarella, ho hanyetsa dikhemikhale le tshebetso tlasa maemo a itseng a tikoloho. Synthesis 1,3-Difluoroacetone e ka etswa ka ho fluorina acetone tlasa maemo a laolwang ho sebediswa di-agent tse fluorinating tse kang hydrogen fluoride (HF) kapa elemental fluorine (F2). Ts'ebetso ya fluorination e nkela diathomo tsa haeterojene sebaka ka acetone ka diathomo tsa fluorine, e leng se hlahisang 1,3-difluoroacetone e le sehlahiswa se seholo. Mekhoa ya ho hlwekisa hangata e kenyelletsa ho ntsha distillation kapa ho ntsha solvent ho fumana DFA e hlwekileng haholo e loketseng ditshebediso tsa indasteri le tsa laboratori. Ka bokhutšoanyane, 1,3-difluoroacetone ke motsoako o feto-fetohang o nang le ts'ebeliso ea bohlokoa ho tsoakoeng ha lintho tse phelang, ts'ebetso ea lik'hemik'hale, le saense ea thepa. Thepa ea eona e ikhethang e le ketone e nang le fluorine e nolofalletsa mesebetsi e fapaneng, e tšehetsa tsoelo-pele makaleng a fapaneng a indasteri le ho kenya letsoho nts'etsopele ea lik'hemik'hale le thepa e ikhethang.
