Engtin nge bisphenol A sodium salt method hi hman a nih?

Bisphenol A BPA a ni sodium chi (sodium chi) a ni method: A hmasa ber chu sodium salt siam a ni: bisphenol A tlemte chu sodium hydroxide aqueous methanol solution-ah dahin, chi siamna atan nitrogen dahin, solvent chu distilled off a ni a, a product chu a vawt a, Bisphenol A BPA sodium salt hmuh a ni. Step hnihnaah chuan phenoxide leh epichlorohydrin hmuh chhuah chu reactor-ah ratio engemaw zat dahin, catalyst atan quaternary ammonium salt engemaw zat dahin, 80~110°C-ah reaction chu kalpui a ni. Reaction zawhah tui silfai leh layer separation tih a ni a, NaCl chu paih chhuah a ni. Tichuan, epichlorohydrin chu vacuum distillation hmangin lakchhuah a ni a, crude product chu a lo chhuak ta a ni. A tawp berah chuan organic solvent te chu extraction leh water washing atan hman a ni a, reaction solution chu layer hrang hrangah then a ni a, organic phase chu hmuh theih a ni a, organic phase chu dried leh distilled hmangin organic solvent chu paih chhuah a ni a, quality sang zawk Bisphenol A BPA-based epoxy resin siam a ni. Mahse, he process hi a buaithlak lutuk a, catalyst separation-ah harsatna a awm a, production cycle rei tak a awm a, chuvangin industrial application a tlem hle.
