i-bisphenol A i-bpa Ukusabela nge-Phosgene — Ukulungiswa kwe-Polycarbonate
Ukusabela kwe-bisphenol A BPA ne-phosgene kuyisinyathelo esibalulekile ekulungiseleleni i-polycarbonate. Kulokhu kusabela, i-athomu ye-carbonyl carbon ku-phosgene ine-electrophilicity enamandla, kanti i-phenolic hydroxyl oxygen atom ye-bisphenol A isebenza njengesikhungo se-nucleophilic ukuyihlasela, yakha umkhiqizo ophakathi. Ngemuva kwalokho, umkhiqizo ophakathi ulahlekelwa yi-molecule eyodwa ye-hydrogen chloride futhi uyaqhubeka nokusabela namanye ama-molecule e-bisphenol A BPA kanye ne-phosgene, kancane kancane i-polymerize ukwakha i-polycarbonate. Lokhu kusabela kuvame ukwenziwa ku-solvent ephilayo, futhi i-ejenti ebopha i-acid idinga ukungezwa ukuze imunce i-hydrogen chloride ekhiqizwa ukusabela ukuze kukhuthazwe ukusabela ukuthi kuqhubeke ngendlela enhle. Izimo ezahlukene zokusabela, njengohlobo lwe-solvent yokusabela, ukukhethwa kwe-ejenti ebopha i-acid, kanye nesikhathi sokusabela, konke kuzothinta ikhwalithi nokusebenza kwe-polycarbonate. Isibonelo, ukukhetha i-solvent ephilayo efanele kungathuthukisa ukuncibilika kwama-reactants futhi kwenze ukusabela kuqhubeke ngendlela efanayo; I-ejenti efanelekile yokubopha i-asidi ingamunca ngempumelelo i-hydrogen chloride, igcine i-asidi kanye ne-alkalinity yesistimu yokusabela, futhi iqinisekise intuthuko ebushelelezi yokusabela.
