Bisphenol a bpa Hydrochloric Acid Lam cu zeidah a si?
Bisphenol A bpa Hydrochloric Acid Lam
Hydrochloric acid asiloah hydrogen chloride gas kha catalysts ah hmannak lam hna cu a dihlak in hydrochloric acid lam tiah auhmi an si. Tahchunhnak ah, phenol le acetone cawhmi cu a ro cangmi hydrogen chloride catalyst he thli hneknak le 50-60°C ah suimilam 8-9 chung an cawh. Gaseous hydrogen chloride volume fraction cu 96% cung ah a um tikah, a bik in chuahmi cu bisphenol A bpa a si, a chuahmi thilri hna cu a isomers, trihydroxy, asiloah monohydroxy derivatives hna he an i tel.
Hi lam in hmuhmi bisphenol A bpa cu epoxy resin sernak caah thilri ah hman khawh a si. Polycarbonate caah hman ding a si ahcun thianh chap a hau. Tahchunhnak ah, Hooker kalning nih bisphenol A cu vacuum distillation le extractive crystallization hmangin a thianh. Bisphenol A bpa ton khat ah hmanmi zat cu 0.855 tons of phenol, 0.269 tons of acetone, 0.216 tons of hydrogen chloride, le 0.011 tons of benzene solvent an si.
Hi lam hi a ttha tein dirhmi a si i batch asiloah pehzulh tein chuah khawhnak phun in hman khawh a si.
