Isebenza njani indlela yetyuwa ye-bisphenol A sodium?

IBisphenol A i-bpa Indlela yetyuwa yesodiyam: Inyathelo lokuqala kukulungiselela ityuwa yesodiyam: isixa esithile se-bisphenol A siyanyibilika kwisisombululo se-methanol esimanzi se-sodium hydroxide, kungeniswa i-nitrogen kwimpendulo yokwenza ityuwa, isinyibilikisi siyanyibilika, kwaye imveliso yomiswa ukuze kufunyanwe ityuwa yesodiyam yeBisphenol A BPA. Inyathelo lesibini libandakanya ukongeza i-phenoxide kunye ne-epichlorohydrin efunyenweyo kwi-reactor kwisilinganiso esithile, kongezwa isixa esithile setyuwa ye-quaternary ammonium njenge-catalyst, kwaye kuqhutywe impendulo kwi-80 ~ 110°C. Emva kwempendulo, ukuhlamba ngamanzi kunye nokwahlula-hlula kwamaleya kwenziwa ukuze kususwe i-NaCl. Emva koko, i-epichlorohydrin isuswa nge-vacuum distillation ukuze kufunyanwe imveliso eluhlaza. Ekugqibeleni, izinyibilikisi ze-organic zisetyenziselwa ukukhupha kunye nokuhlamba ngamanzi, isisombululo sempendulo sahlulwe sibe ngamaleya ukuze kufunyanwe isigaba se-organic, kwaye isigaba se-organic somiswa kwaye sinyibilikiswe ukuze kususwe isinyibilikisi se-organic, nto leyo evelisa i-epoxy resin ekumgangatho ophezulu yeBisphenol A BPA. Nangona kunjalo, le nkqubo inzima kakhulu, inobunzima ekuhlukaniseni i-catalyst, umjikelo wemveliso omde, kwaye ngaloo ndlela ukusetyenziswa kwayo kuncinci kwimizi-mveliso.
