| Abstract: | A series of Pd Au KAc/SiO 2 catalysts were prepared by equal volume impregnation method, and were used in synthesis of vinyl acetate through vapor phase acetoxylation of ethylene. The advantageous reaction conditions were found as follows: reaction temperature 140142 ℃, concentrations of O 2 and HAc in feed gas are 5%6%, 11%13% respectively. The influences of various conditions on the catalytic performance, such as pressure, space velocity, distribution of active components, promotor and abnormally shaped catalysts were studied also. |
