Indlela ye-bisphenol A yeluswayi lwe-sodium isebenta njani?

I-Bisphenoli i-BPA luswayi lwe-sodium indlela: Sinyatselo sekucala kulungiselela luswayi lwe sodium: linani lelitsite le bisphenol A lincibilikiswa esixazululweni se methanol lesemantini se sodium hydroxide, initrogen yetfulwa kwentela kuphendvula lokwakha luswayi, lesincibilikisi siyahlungwa, bese lomkhicito womiswa kutfola i Bisphenol A BPA. Sinyatselo sesibili sifaka ekhatsi kwengeta le phenoxide letfoliwe kanye ne epichlorohydrin ibe yi reactor ngesilinganiso lesitsite, kwengeta linani lelitsite le luswayi lwe ammonium ye quaternary njengesikhutsato, kanye nekuchuba le reactor ku 80~110°C. Ngemuva kwekuphendvula, kugeza ngemanti kanye nekuhlukaniswa kwelucwencwe kwentiwa kususa iNaCl. Ngemuva kwaloko, i-epichlorohydrin isuswa ngekuvutsiwa kwemshini wekuvubela kwentela kutfola lomkhicito longakahlutwa. Ekugcineni, tintfo letiphilako tisetjentiselwa kukhipha kanye nekugeza ngemanti, lesisombululo sekuphendvula sihlukaniswe sibe tincenye kwentela kutfola sigaba setilwane, bese lesigaba setilwane siyasomiswa bese siyahlungwa kwentela kususa letintfo letiphilako, kukhicita iBisphenol A BPA-based epoxy resin lesezingeni leliphakeme. Nomakunjalo, lenchubo iyinkimbinkimbi kakhulu, ngebumatima ekuhlukanisweni kwe catalyst, umjikeleto wekukhicita lomudze, ngaleyondlela kusetjentiswa kwetimboni lokulinganiselwe.
