Isingeniso

I-1,1-Dichloro-2,2-difluoroethylene, eyaziwa nangokuthi i-CF2ClCF2Cl, iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sobunjalo bayo, ukusetshenziswa, indlela yokulungiselela kanye nolwazi lokuphepha:

 

Ikhwalithi:

I-1,1-Dichloro-2,2-difluoroethylene iwuketshezi olungenambala olunephunga elingavamile. Iminyene futhi ayincibiliki emanzini, kodwa ingancibilika kuzincibilikisi eziningi eziphilayo.

 

Sebenzisa:

I-1,1-Dichloro-2,2-difluoroethylene inezinhlobonhlobo zokusetshenziswa embonini yamakhemikhali. Kuyi-solvent ebalulekile esetshenziswa kakhulu ukuncibilikisa noma ukuhlambulula izinhlanganisela eziningi ze-organic. Ibuye isetshenziswe njengesiqandisi nesiqandisi, futhi isetshenziselwa ukwenza ama-fluoroelastomers, ama-fluoroplastics, amafutha okugcoba, nezinto ezibonakalayo, phakathi kokunye. Embonini ye-elekthronikhi, iphinde isetshenziswe njengempahla eluhlaza yokuhlanza ama-ejenti nezinto zokwakha ezinomshini ophezulu we-dielectric.

 

Indlela:

Ukulungiswa kwe-1,1-dichloro-2,2-difluoroethylene kuvame ukutholakala ngokusabela i-1,1,2-trifluoro-2,2-dichloroethane nge-copper fluoride. Ukusabela kwenziwa emazingeni okushisa aphezulu futhi phambi kwe-catalyst.

 

Ulwazi Lokuphepha:

I-1,1-Dichloro-2,2-difluoroethylene iyisithako esiyingozi, futhi ukuchayeka noma ukuhogela umhwamuko wayo kungabangela ukucasuka kwamehlo, ukuphefumula kanye nesikhumba. Ukuchayeka ekugxilweni okuphezulu kungase kubangele nomonakalo ohlelweni lwezinzwa olumaphakathi namaphaphu. Izinyathelo zokuphepha ezidingekayo kufanele zithathwe ngesikhathi sokusetshenziswa, njengokugqoka izinto zokuzivikela ezifanele, ukuqinisekisa ukuthi kungena umoya omuhle, njll. Inhlanganisela kufanele igcinwe kahle futhi ilahlwe ukuze kugwenywe ukungcoliswa kwemvelo.
