2-(Trifluoromethoxy)benzoic acid (CAS# 1979-29-9) Intshayelelo
I-TFMPA yikristale engenambala, enyibilikayo kwizinyibilikisi eziphilayo ezifana ne-benzene kunye ne-ethanol. Ineasidi eyomeleleyo kunye ne-oxidation, kwaye iyachukumiseka emanzini.
Sebenzisa:
I-TFMPA isetyenziswa ngokubanzi njenge-acid catalyst, i-oxidant kunye ne-catalyst ye-esterification kwi-organic synthesis. Inokukhuthaza ukuqhubela phambili kokusabela kweekhemikhali kunye nokuphucula ukukhetha kunye nesivuno sokuphendula.
Indlela:
Ulungiselelo lwe-TFMPA ludla ngokuqhutywa kukusabela kwamanyathelo amaninzi. Enye indlela eqhelekileyo yokulungisa kukusabela i-trifluoromethane nge-chloromethylbenzene ukuvelisa i-2-chloromethyl-3-(trifluoromethoxy) benzene (CF3CH2OH) kunye ne-reaction substrate. Emva koko, i-react substrate iphendulwa nge-agent oxidizing ukufumana i-TFMPA.
Ulwazi ngoKhuseleko:
Ukusebenza ngokukhuselekileyo kwe-TFMPA kufuneka kulandele imigaqo yokhuseleko yelabhoratri. Ngenxa ye-acidity kunye ne-oxidation, kufuneka igweme ukudibanisa nezinto ezinokutsha, i-solvents eziphilayo kunye neegesi ezivuthayo. Izixhobo ezifanelekileyo zokuzikhusela ezinje ngeglavu zelebhu, iiglasi kunye neempahla zaselebhu kufuneka zinxitywe ngexesha lokusebenza. Kwangaxeshanye, kufuneka iqhutywe kwindawo enomoya kakuhle ukukhusela ukuqokelelana kweegesi eziyingozi.
