Falcelinta ka dhaxaysa bisphenol A iyo phosgene waa tallaabo muhiim ah oo lagu diyaarinayo polycarbonate.

bisfenol A bpa Falcelinta Phosgene — Diyaarinta Polycarbonate
Falcelinta bisphenol A BPA oo leh phosgene waa tallaabo muhiim ah oo lagu diyaarinayo polycarbonate. Falcelintan, atamka kaarboonyl ee ku jira phosgene wuxuu leeyahay elektrofilitik xooggan, atamka oksijiinta phenolic hydroxyl ee bisphenol A wuxuu u dhaqmaa sidii xarun nukliyeelik ah si uu u weeraro, isagoo samaynaya badeeco dhexdhexaad ah. Kadib, badeecada dhexdhexaadka ah waxay lumisaa hal molecule oo ah hydrogen chloride waxayna sii waddaa inay la falgasho molecules kale oo bisphenol A BPA ah iyo phosgene, iyadoo si tartiib tartiib ah u polymeraysa si ay u samayso polycarbonate. Falcelintan waxaa badanaa lagu sameeyaa dareere dabiici ah, waxaana loo baahan yahay in lagu daro wakiil aashito ku xidhan si uu u nuugo hydrogen chloride-ka uu soo saaro falgalka si kor loogu qaado falgalka si uu ugu socdo jihada togan. Xaaladaha falgalka ee kala duwan, sida nooca dareeraha falgalka, xulashada wakiilka ku xidhan aashitada, iyo waqtiga falgalka, dhammaantood waxay saameyn doonaan tayada iyo waxqabadka polycarbonate. Tusaale ahaan, doorashada dareere dabiici ah oo ku habboon waxay hagaajin kartaa milmida falgalayaasha waxayna ka dhigi kartaa falgalku inuu si isku mid ah u socdo; Wakiilka ku habboon ee aashitada ku xidha ayaa si wax ku ool ah u nuugi kara haydarojiin kloriid, ilaalin kara aashitada iyo alkalinity-ga nidaamka falgalka, wuxuuna hubin karaa horumarka siman ee falgalka.
