Kev Tsim Kho Tshuab Ntawm Acetate

Tam sim no, lub ntsiab catalyst rau butyl acetate industrial ntau lawm yog sulfuric acid. Nws yog tsim los ntawm esterification ntawm acetic acid thiab butanol nyob rau hauv lub xub ntiag ntawm sulfuric acid catalyst. acetic acid, butanol thiab sulfuric acid yog rhuab nyob rau hauv lub reactor mus rau 89 degree C. Tom qab cov tshuaj tiv thaiv, lub vapor uas muaj butyl acetate, butanol thiab dej raug tshem tawm thiab condensed, thiab lub sab sauv txheej yog pub rau hauv ib tug pej thuam nrog ib tug reboiler nyob rau hauv nws. Cov cawv uas tsis muaj tshuaj tiv thaiv tau tshwm sim thiab kis mus rau lub reactor. Lub crude ester sib tov yog tom qab ntawd distilled zaum ob los cais butyl acetate los ntawm lwm yam khoom los ntawm cov khoom.
