Txoj Kev Siv Bisphenol a bpa Hydrochloric Acid yog dab tsi?
Bisphenol a bpa Txoj Kev Hydrochloric Acid
Cov txheej txheem siv hydrochloric acid lossis hydrogen chloride roj ua cov catalysts raug hu ua hydrochloric acid method. Piv txwv li, ib qho sib tov ntawm phenol thiab acetone raug tshuaj nrog cov tshuaj hydrogen chloride qhuav ntawm qhov siab ntawm huab cua thiab 50–60 ° C rau 8–9 teev. Thaum qhov ntim ntawm cov pa hydrogen chloride tseem nyob siab tshaj 96%, cov khoom tseem ceeb yog bisphenol A bpa, nrog rau cov khoom lag luam suav nrog nws cov isomers, trihydroxy, lossis monohydroxy derivatives.
Cov bisphenol A bpa uas tau los ntawm txoj kev no siv tau ua cov khoom siv raw rau kev tsim cov epoxy resin. Yuav tsum tau ua kom huv ntxiv yog tias yuav siv rau polycarbonate. Piv txwv li, cov txheej txheem Hooker ua kom huv bisphenol A siv cov tshuab nqus tsev thiab cov khoom siv rho tawm. Cov nqi siv ib tuj ntawm bisphenol A bpa yog kwv yees li 0.855 tons ntawm phenol, 0.269 tons ntawm acetone, 0.216 tons ntawm hydrogen chloride, thiab 0.011 tons ntawm benzene solvent.
Txoj kev no tau tsim zoo thiab tuaj yeem ua haujlwm hauv ob qho tib si batch lossis tas mus li.
