Kedu ka bisphenol A si emeghachi omume na phosgene iji kwadebe polycarbonate

bisfenol A bpa Mmeghachi omume na Phosgene — Nkwadebe nke Polycarbonate
Mmeghachi omume nke bisphenol A BPA na phosgene bụ nzọụkwụ dị mkpa na nkwadebe nke polycarbonate. N'ime mmeghachi omume a, atọm carbonyl carbon dị na phosgene nwere ike electrophilicity siri ike, atọm oxygen phenolic hydroxyl nke bisphenol A na-arụ ọrụ dị ka ebe etiti nucleophilic iji wakpo ya, na-emepụta ngwaahịa etiti. Mgbe ahụ, ngwaahịa etiti ahụ na-efunahụ otu molekul hydrogen chloride ma na-aga n'ihu na-emeghachi omume na molekul bisphenol A BPA na phosgene ndị ọzọ, na-eme ka polymer dị nwayọ nwayọ iji mepụta polycarbonate. A na-emekarị mmeghachi omume a na ihe mgbaze organic, a ga-agbakwunye ihe na-ejikọ acid iji nabata hydrogen chloride nke mmeghachi omume ahụ mepụtara iji kwalite mmeghachi omume ahụ ka ọ gaa n'ihu n'ụzọ dị mma. Ọnọdụ mmeghachi omume dị iche iche, dị ka ụdị ihe mgbaze mmeghachi omume, nhọrọ nke ihe na-ejikọ acid, na oge mmeghachi omume, niile ga-emetụta ogo na arụmọrụ nke polycarbonate. Dịka ọmụmaatụ, ịhọrọ ihe mgbaze organic kwesịrị ekwesị nwere ike ime ka mgbaze nke ndị na-emeghachi omume dịkwuo mma ma mee ka mmeghachi omume ahụ gaa n'ihu n'otu aka ahụ; ihe na-ejikọ acid kwesịrị ekwesị nwere ike ịmịkọrọ hydrogen chloride nke ọma, nọgide na-enwe acidity na alkalinity nke sistemụ mmeghachi omume, ma hụ na mmeghachi omume ahụ na-aga nke ọma.
