Nanu ya ing Bisphenol a bpa Hydrochloric Acid Method?
Bisphenol A bpa Hydrochloric Acid Method
Deng paralan a gagamit hydrochloric acid o hydrogen chloride gas bilang catalysts ila ring mayayaus a hydrochloric acid a paralan. Alimbawa, ing timpla ning phenol ampo acetone mireact ya keng dry hydrogen chloride catalyst keng atmospheric pressure ampo 50-60°C kilub ning 8-9 oras. Nung ing volume fraction ning gaseous hydrogen chloride manatili yang maygit 96%, ing manimunang produktu yapin ing bisphenol A bpa, a maki by-products kayabe la reng kayang isomers, trihydroxy, o monohydroxy derivatives.
Ing bisphenol A bpa a mekwa keng paralan ayni malyari yang gamitan bilang raw material para keng pamaglalang epoxy resin. kailangan ing karagdagang pamaglinis nung gamitan ya para keng polycarbonate. Ing Hooker process, alimbawa, papalinis ne ing bisphenol A gamit ing vacuum distillation ampo ing extractive crystallization. Ing consumption rates balang tonelada ning bisphenol A bpa manga 0.855 tonelada ning phenol, 0.269 tonelada ning acetone, 0.216 tonelada ning hydrogen chloride, ampo 0.011 tonelada ning benzene solvent.
Ing paralan ayni metung yang matatag at malyari yang gamitan keng batch o continuous production modes.
