    Xana ndlela ya bisphenol A ya munyu wa sodium yi tirhisiwa njhani?

    2. 2.025-10-27

    Bisphenol A BPA munyu wa sodium ndlela: Goza rosungula i ku lulamisiwa ka munyu wa sodium: nhlayo yokarhi ya bisphenol A yi pfanganisiwa eka aqueous methanol solution ya sodium hydroxide, nitrogen yi nghenisiwa eka ku endla munyu, solvent yi distilled off, naswona xiendliwa xi omisiwa kuva ku kumiwa Bisphenol A BPA sodium salt. Goza ravumbirhi ri katsa ku chela phenoxide leyi kumiweke na epichlorohydrin eka reactor hi ratio yokarhi, ku chela nhlayo yokarhi ya quaternary ammonium salt tani hi catalyst, naku fambisa reaction eka 80~110°C. Endzhaku ka reaction, ku hlantswiwa hi mati xikan’we naku hambanyisa layer swiendliwa kuva ku susiwa NaCl. Kutani, epichlorohydrin yi susiwa hi vacuum distillation kuva ku kumiwa xitirhisiwa lexi nga si swekiwaka. Eku heteleleni, ti organic solvents titirhisiwa eka ku humesiwa naku hlantswiwa hi mati, reaction solution yi hambanisiwa hi ti layers kuva yikuma organic phase, naswona organic phase yi omisiwa naku distilled kuva yi susa organic solvent, leswi humesaka khwalithi yale henhla ya Bisphenol A BPA-based epoxy resin. Hambiswiritano, endlelo leri ri rharhanganile ngopfu, laha kungana swiphiqo eka ku hambanyisa ti catalyst, xirhendzevutani xo leha xa vuhumelerisi, naswona xisweswo ku tirhisiwa ka ti indasitiri lokunga ringanelangiki.
