Txoj kev siv propionic acid thiab propionic acid ethanol carbonation yog dab tsi?
Propionic Acid thiab propanoic acid Ethanol Carbonylation Txoj Kev
Txoj kev no tau tsim los ntawm lub tuam txhab A. Hauv cov kua qaub nruab nrab ntawm 250–350 ° C thiab 10–30 MPa, siv cov tshuaj catalysts xws li boron trifluoride, carbon tetrachloride, tooj liab acetate, halides ntawm manganese, txhuas, nickel, cobalt, lossis hlau, thiab cov kua qaub ntawm chromium, molybdenum, lossis tungsten, ethanol reacts nrog carbon monoxide hauv theem kua los tsim cov propionic acid, nrog rau cov txiaj ntsig ntawm 90%. Txawm li cas los xij, vim muaj teeb meem tsis tau daws xws li tus nqi tshuaj tiv thaiv, cov txiaj ntsig, kev poob catalyst, thiab cov khoom siv xeb hauv qab qhov kub thiab siab, txoj kev no tsis tau txais kev pom zoo dav hauv kev lag luam propionic acid thiab propanoic acid.
