Uburyo bwa bisphenol A sodium salt bukorwa bute?

Bisphenol A bpa Uburyo bw'umunyu wa sodiyumu: Intambwe ya mbere ni ugutegura umunyu wa sodiyumu: ingano runaka ya bisphenol A ishongeshwa mu gisubizo cya methanol y'amazi cya sodiyumu hifashishijwe hydroxide ya sodiyumu, azote ishyirwamo kugira ngo habeho umunyu, umuti uvangwa, hanyuma umusaruro wumuke kugira ngo haboneke umunyu wa sodiyumu wa Bisphenol A BPA. Intambwe ya kabiri irimo kongeramo phenoxide na epichlorohydrin byabonetse mu cyuma gitunganya imiterere ku gipimo runaka, kongeramo umunyu wa ammonium wa quaternary nk'umuti, no gukora reaction kuri 80 ~ 110°C. Nyuma y'irangizwa, gukaraba amazi no gutandukanya imiterere kugira ngo NaCl ikureho. Hanyuma, epichlorohydrin ikurwaho hakoreshejwe vacuum distillation kugira ngo haboneke umusaruro ukomoka ku bimera. Amaherezo, imiti ikomoka ku bimera ikoreshwa mu gukuramo no gukaraba amazi, umuti ukomoka ku bimera ugabanywamo imiterere kugira ngo haboneke imiterere, hanyuma imiterere ikomoka ku bimera yumuke kandi igakurwamo umwuka kugira ngo ikureho umuti ukomoka ku bimera, bityo igatanga epoxy resin nziza ya Bisphenol A BPA. Ariko, iyi nzira iragoye cyane, ifite ingorane mu gutandukanya catalyst, ukwezi kure, bityo ikaba ari imbogamizi mu nganda.
