Yintoni iBisphenol a bpa Hydrochloric Acid Method?
IBisphenol a i-bpa Indlela yeHydrochloric Acid
Iindlela ezisebenzisa i-hydrochloric acid okanye i-hydrogen chloride gas njengee-catalysts zibizwa ngokuba yindlela ye-hydrochloric acid. Umzekelo, umxube we-phenol kunye ne-acetone uphendulwa nge-hydrogen chloride catalyst eyomileyo kuxinzelelo lomoya kunye ne-50-60°C kangangeeyure ezi-8-9. Xa iqhekeza levolumu ye-hydrogen chloride yegesi lihlala lingaphezulu kwe-96%, imveliso ephambili yi-bisphenol A bpa, enemveliso eziquka ii-isomers zayo, i-trihydroxy, okanye i-monohydroxy derivatives.
I-bisphenol A bpa efunyenwe ngale ndlela ingasetyenziswa njengezinto eziluhlaza ukuvelisa i-epoxy resin. Kufuneka ukucoca ngakumbi ukuba iza kusetyenziselwa i-polycarbonate. Umzekelo, inkqubo yeHooker ihlaziya i-bisphenol A isebenzisa i-vacuum distillation kunye ne-extractive crystallization. Amanani okusetyenziswa ngetoni nganye ye-bisphenol A bpa amalunga neetoni ezingama-0.855 ze-phenol, iitoni ezingama-0.269 ze-acetone, iitoni ezingama-0.216 ze-hydrogen chloride, kunye neetoni ezingama-0.011 ze-benzene solvent.
Le ndlela imiselwe kakuhle kwaye ingasetyenziswa ngeendlela zemveliso eziqhubekekayo okanye ezibanzi.
