Ino nzila ya bisphenol A sodium salt ibelesegwa biyeni?

Bisphenol A BPA munyo wa sodium nzila: Ntaamu yakusaanguna nkubamba munyo wa sodium: mweelwe umwi wa bisphenol A ulanyonyooka mumusamu wa methanol wamaanzi wa sodium hydroxide, nitrogen ilanjizigwa mukupanga munyo, munyo ulasofwaazyigwa, mpawo eecho chiyuminizyigwa kuti chijane munyo wa Bisphenol A BPA sodium. Ntaamu yabili ibikkilizya kubikka phenoxide antoomwe a epichlorohydrin mumuncini uubelesya mulilo amweelwe umwi, kuyungizya mweelwe umwi wa quaternary ammonium salt mbuli chintu chigwasya, mpawo kuchita mulimu ooyu a 80~110°C. Musule aakusanduka, kusanzya amaanzi akuandaanya zibeela zyachitika kuchitwa kuchitila kuti NaCl igwisyigwe. Mpawo, epichlorohydrin ilagwisigwa kwiinda mukubelesya nzila ya vacuum distillation kuti kujane chintu chitakwe busani. Kumamanino, zintu zipona zibelesyegwa kugwisya akusanzya amaanzi, musamu wakusanganya ulaandaanizyigwa muzibeela kutegwa ujane cibeela cabuumi, mpoonya cibeela cabuumi cilayuminizyigwa akusanzyigwa kutegwa kugwisigwe cibeela cabuumi, calo cipa kuti kube Bisphenol A BPA-based epoxy resin iili kabotu. Nokuba boobo, eeyi nzila njiyumu loko, kiijisi buyumuyumu bwakwaandaanya zintu zipa kuti zintu zibe kabotu, chiindi chilamfu chakupanga, aboobo tazibelesyegwi kapati mumafakitali.
