Yini i-Bisphenol a bpa Hydrochloric Acid Method?
I-Bisphenol A bpa Indlela ye-Hydrochloric Acid
Iindlela ezisebenzisa i-hydrochloric acid nofana i-hydrogen chloride gas njenge-catalysts zibizwa ngokuthi yi-hydrochloric acid method. Ukwenza isibonelo, ingxube ye-phenol ne-acetone ihlanganiswa ne-hydrogen chloride catalyst eyomileko nge-atmospheric pressure kanye nama-50-60°C ama-awa ayi-8-9. Lokha i-volumu fraction ye-gaseous hydrogen chloride ihlala ingaphezu kwama-96%, umkhiqizo omkhulu yi-bisphenol A bpa, enemikhiqizo ehlukileko efaka hlangana ama-isomer wayo, i-trihydroxy, nofana i-monohydroxy derivatives.
I-bisphenol A bpa etholwe ngalendlela ingasetjenziswa njengesisetjenziswa sokwenza i-epoxy resin. Ukuhlanzwa okungeziweko kuyatlhogeka nangabe kuzokusetjenziselwa i-polycarbonate. Ikambiso ye-Hooker, ngokwesibonelo, ihlanza i-bisphenol A ngokusebenzisa ukuvundiswa kwe-vacuum nokukhipha amakristalu. Amazinga wokusetjenziswa ngethani le-bisphenol A bpa angaba mathani ama-0.855 we-phenol, amathani ama-0.269 we-acetone, amathani ama-0.216 we-hydrogen chloride, kanye namathani ama-0.011 we-benzene solvent.
Indlela le isungulwe kuhle begodu ingasetjenziswa ngeendlela zokukhiqiza eziqoqiweko nofana eziragela phambili.
