Ɔkwan bɛn so na wɔde bisphenol A sodium nkyene kwan no di dwuma?

Bisphenol A BPA na ɛyɛ adwuma sodium nkyene a wɔde yɛ ɔkwan: Anamɔn a edi kan ne sodium nkyene a wɔyɛ: wɔde bisphenol A dodow bi gu sodium hydroxide a wɔde methanol afra mu nsu mu, wɔde nitrogen hyɛ mu ma nkyene a wɔde yɛ adwuma no, wɔma aduru no fi mu, na wɔma ade no we ma wonya Bisphenol A BPA sodium nkyene. Anamɔn a ɛtɔ so mmienu no hwehwɛ sɛ wɔde phenoxide ne epichlorohydrin a wɔanya no bɛka reactor mu wɔ ratio pɔtee bi mu, de quaternary ammonium nkyene dodoɔ bi aka ho sɛ catalyst, na wɔayɛ reaction no wɔ 80~110°C. Wɔ adeyɛ no akyi no, wɔyɛ nsu hohoro ne layer separation de yi NaCl fi hɔ. Afei, wɔde vacuum distillation yi epichlorohydrin na ama wɔanya ade a wɔmfa nhyehyɛ mu no. Awiei koraa no, wɔde organic solvents di dwuma de yiyi ne nsu hohoro, wɔtetew reaction solution no mu yɛ no ntoatoaso ma wonya organic phase no, na wɔma organic phase no we na wɔ distilled de yi organic solvent no, na ɛma wonya Bisphenol A BPA-based epoxy resin a ɛkorɔn. Nanso, saa adeyɛ yi yɛ nea ɛyɛ den dodo, na ɛyɛ den sɛ wɔbɛtetew nneɛma a ɛma nneɛma yɛ kɛse mu, ɛyɛ adwuma bere tenten, na enti ɛnyɛ nea wɔde di dwuma wɔ mfiridwuma mu.
