bisphenol A bpa Kugadzirisa nePhosgene — Kugadzirira Polycarbonate
Kuita kwebisphenol A BPA nephosgene idanho guru mukugadzirira polycarbonate. Mukuita uku, atomu yecarbonyl carbon iri muphosgene ine electrophilicity yakasimba, uye phenolic hydroxyl oxygen atomu yebisphenol A inoshanda senzvimbo ye nucleophilic kurwisa, ichigadzira chigadzirwa chepakati. Zvadaro, chigadzirwa chepakati chinorasikirwa nemorekuru imwe yehydrogen chloride uye chinoramba chichipindura nemamwe mamorekuru ebisphenol A BPA nephosgene, zvichipomesa zvishoma nezvishoma kuti zvigadzire polycarbonate. Kuita uku kunowanzoitwa mu organic solvent, uye acid-binding agent inofanira kuwedzerwa kuti itore hydrogen chloride inogadzirwa ne reaction kuti isimudzire reaction kuti ienderere mberi nenzira yakanaka. Mamiriro akasiyana e reaction, akadai serudzi rwe reaction solvent, kusarudzwa kweacid-binding agent, uye nguva ye reaction, zvese zvinokanganisa kunaka nekushanda kwepolycarbonate. Semuenzaniso, kusarudza organic solvent yakakodzera kunogona kuvandudza kunyungudika kwe reactants uye kuita kuti reaction ienderere mberi zvakaenzana; chinhu chakakodzera chinosunga acid chinogona kupinza hydrogen chloride zvinobudirira, kuchengetedza acidity uye alkalinity ye reaction system, uye kuona kuti reaction inofamba zvakanaka.
