Nzira yemunyu we sodium bisphenol A inoshandiswa sei?

Bisphenol A bpa Nzira yemunyu weSodium: Danho rekutanga kugadzirira munyu wesodium: huwandu hwakati hwebisphenol A hunonyungudutswa mumushonga we sodium hydroxide une mvura, nitrogen inounzwa kuti iite munyu, munyu unonyungudutswa, uye chigadzirwa chinoomeswa kuti pave neBisphenol A BPA sodium salt. Danho rechipiri rinosanganisira kuwedzera phenoxide ne epichlorohydrin zvinowanikwa mu reactor pane imwe ratio, kuwedzera huwandu hwakati hwe quaternary ammonium salt se catalyst, uye kuita reaction pa80~110°C. Mushure me reaction, kugeza nemvura nekuparadzanisa layer zvinoitwa kubvisa NaCl. Zvadaro, epichlorohydrin inobviswa ne vacuum distillation kuti pave ne crude product. Pakupedzisira, organic solvents inoshandiswa pakuburitsa nekusuka mvura, reaction solution inopatsanurwa kuita layers kuti pave ne organic phase, uye organic phase inoomeswa uye inonyungudutswa kuti ibvise organic solvent, zvichipa Bisphenol A BPA-based epoxy resin yepamusoro. Zvisinei, maitiro aya akaoma zvakanyanya, ane matambudziko ekuparadzanisa catalyst, kutenderera kwenguva refu kwekugadzira, uye nekudaro kushandiswa kushoma kwemaindasitiri.
