bisphenol A bpa Reaksyun keng Phosgene — Pamagsadya keng Polycarbonate
Ing reaksyun ning bisphenol A BPA keng phosgene metung yang susi keng pamagsadya ning polycarbonate. Kening reaksiun, ing carbonyl carbon atom keng phosgene atin yang masikan a electrophilicity, ampo ing phenolic hydroxyl oxygen atom ning bisphenol A gagawan neng nucleophilic center para ataki ne, at gagawang intermediate product. Kaybat, ing intermediate product mawawala yang metung a molecule ning hydrogen chloride at patuloy yang makipagreact kareng aliwang bisphenol A BPA molecules ampo phosgene, bagya-bagya yang mag-polymerize para maging polycarbonate. Ing reaksyun ayni keraklan gagawan de keng organic a solvent, at kailangan yang idagdag ing acid-binding agent para asipsip ne ing hydrogen chloride a gewa ning reaksyun para isulong ing reaksyun para isundu ing positibong direksyun. Deng miyayaliwang kundisyun ning reaksyun, antimo ing uri ning solvent ning reaksyun, ing pamili ning acid-binding agent, ampo ing oras ning reaksyun, makaapektu la ngan keng kalidad ampo performance ning polycarbonate. Alimbawa, ing pamamili keng masanting a organic solvent malyari yang magpasanting keng solubility da reng reactants ampo gawang mas pare-pareu ing reaksyun; ing metung a masanting a acid-binding agent epektibung makasipsip keng hydrogen chloride, makapanatili keng acidity ampo alkalinity ning reaction system, ampo makasiguradung masalese ing pamagprogresu ning reaction.
