Bisphenol a bpa Metotia o le Hydrochloric Acid
O auala e faʻaaogaina ai le hydrochloric acid poʻo le hydrogen chloride gas e fai ma catalysts e taʻua faʻatasi o le hydrochloric acid method. Mo se faʻataʻitaʻiga, o le faʻafefiloi o le phenol ma le acetone e faʻafefiloi ma le hydrogen chloride catalyst mago i le mamafa o le ea ma le 50–60°C mo le 8–9 itula. A tumau pea le vaega tele o le kasa hydrogen chloride i luga atu o le 96%, o le oloa autu o le bisphenol A bpa, faʻatasi ai ma oloa e aofia ai ona isomers, trihydroxy, poʻo monohydroxy derivatives.
O le bisphenol A bpa e maua mai i lenei metotia e mafai ona faʻaaogaina o se mea mata mo le gaosiga o le epoxy resin. E manaʻomia nisi faʻamamāga pe afai o le a faʻaaogaina mo le polycarbonate. O le faiga a Hooker, mo se faʻataʻitaʻiga, e faʻamamāina ai le bisphenol A e faʻaaoga ai le vacuum distillation ma le extractive crystallization. O le fua faatatau o le faʻaaogaina i le tone o le bisphenol A bpa e tusa ma le 0.855 tone o le phenol, 0.269 tone o le acetone, 0.216 tone o le hydrogen chloride, ma le 0.011 tone o le benzene solvent.
O lenei metotia ua leva ona faʻavaeina ma e mafai ona faʻaaogaina i ni auala gaosiga faʻaputu pe faʻaauau pea.
