Txoj Kev Siv Bisphenol A BPA Sulfuric Acid Ua Haujlwm Li Cas?
Bisphenol A bpa Txoj Kev Siv Sulfuric Acid
Phenol thiab acetone raug cov tshuaj tiv thaiv condensation hauv sulfuric acid nrog qhov concentration ntawm 72.5% -73.0% ntawm 35-45 ° C. Tom qab ntawd cov khoom raug ntxuav nrog dej, crystallized, sib cais los ntawm centrifugation, thiab ziab kom tau txais bisphenol A uas haum rau cov epoxy resins dav dav thiab cov nplaim taws retardants. Cov nqi siv ib tuj ntawm cov khoom yog kwv yees li 0.925 tons ntawm phenol, 0.285 tons ntawm acetone, thiab 0.500 tons ntawm sulfuric acid (98% purity).
Txoj kev Bisphenol A bpa no muaj cov khoom siv thiab cov txheej txheem yooj yim heev. Txawm li cas los xij, nws raug kev txom nyem los ntawm kev siv cov khoom siv raw ntau, ua rau cov nqi khoom nce siab. Nws kuj ua rau cov khoom siv xeb, cov kav dej, cov qhov dej, thiab qhov chaw tsim khoom, thaum tsim cov khib nyiab ntau heev. Ntxiv mus, qhov zoo ntawm cov khoom tsis ua tau raws li qhov yuav tsum tau ua rau kev tsim cov polycarbonate lossis cov khoom noj khoom haus epoxy resins.
