Abstract
Catalytic oxidation of 1-butene l for a., 6etic acid was studied over vanadium oxide catalysts supported on silica in the presence of steam at temperature range of 200N300C.Binary and ternary oxide catalyst systems containing SnO2, WO3 and TiOdii as the second or the thild componenntt exhibited selective formation of acetic acid, w, hile both activisy and selectivity wer6 poor in the absence of these promoters. The selectivity to qcetic acid -was dependent mainly on the reaction temperature and the catalyst compositig. n, but ip. depepde. pt of the Conversiori of butene. Over the catalyst of V-Sn-W (1: 1: 0.5) oxide on silica, acetic acid was produced with se1 vity, of 50-55% and 45-50%at 225. C and 250, respectively,
