Studies on a New Catalyst for Synthesisof Vinyl Acetate via the Acetylene MethodI The Catalyst Impregnation, Evaluation and Kinetics Studies

AbstrcatIn the study of the catalyst impregnation using the Yangyuan active carbon, the factors affecting the supporting amount of zinc acetate on the active carbon have been correlated. The optimal supported amount of zinc acetate has been obtained by the experiments of the reaction kinetics of acetylene and acetic acid on the catalyst. The new catalyst used and BPL catalysts were investigated in a nongradient reactor. The synthesis of vinyl acetate was experimentally dominated by the acetylene adsorption. Based on the evaluation of the catalyst, the kinetic models of the two catalysts were established.
