Pehea e hana ai ka bisphenol A me ka phosgene e hoʻomākaukau i ka polycarbonate

bisphenol A bpa Ka Hana ʻana me Phosgene — Ka Hoʻomākaukau ʻana o ka Polycarbonate
ʻO ka hana ʻana o ka bisphenol A BPA me ka phosgene kahi hana koʻikoʻi i ka hoʻomākaukau ʻana o ka polycarbonate. Ma kēia hana, he electrophilicity ikaika ka ʻātoma carbonyl carbon i loko o ka phosgene, a ʻo ka ʻātoma oxygen phenolic hydroxyl o ka bisphenol A e hana ma ke ʻano he kikowaena nucleophilic e hoʻouka iā ia, e hana ana i kahi huahana waena. A laila, nalowale ka huahana waena i hoʻokahi molekala o ka hydrogen chloride a hoʻomau i ka hana ʻana me nā molekala bisphenol A BPA ʻē aʻe a me ka phosgene, e polymerizing mālie ana e hana i ka polycarbonate. Hoʻokō pinepine ʻia kēia hana i loko o kahi mea hoʻoheheʻe organik, a pono e hoʻohui ʻia kahi mea hoʻopaʻa waikawa e omo i ka hydrogen chloride i hana ʻia e ka hana e hoʻolaha i ka hana e holomua i ke ala maikaʻi. ʻO nā kūlana hana like ʻole, e like me ke ʻano o ka mea hoʻoheheʻe hopena, ke koho ʻana o ka mea hoʻopaʻa waikawa, a me ka manawa hana, e hoʻopilikia i ka maikaʻi a me ka hana o ka polycarbonate. No ka laʻana, ʻo ke koho ʻana i kahi mea hoʻoheheʻe organik kūpono hiki ke hoʻomaikaʻi i ka solubility o nā reactants a hoʻomau i ka hana like; hiki i kahi mea hoʻopaʻa waikawa kūpono ke omo pono i ka hydrogen chloride, mālama i ka acidity a me ka alkalinity o ka ʻōnaehana hopena, a hōʻoia i ka holomua mālie o ka hopena.
