CATALYTIC ACETYLATION OF ACETYLENE IN VAPOR PHASE

Annotatsiya

The acetylating reaction of acetylene in the presence of nanocatalysts (ZnO)x * (CdO)y * ZrO2)z has been studied. By changing partial pressure of initial substances in a wide interval of parameters’ change the objective laws were studied. On the basis of experimental and literature data stage scheme of reaction mechanism and various options of kinetic equations of acetylating reaction of acetylene have been offered and evaluated their adequacy. On the basis of adequate kinetic equation optimum conditions of synthesis of vinyl acetate from acetylene were chosen: T = 180-2200C, Vcat = 100 ml; C2H2 : CH3COOH = 4:1; = 280 h-1 cat. According to experimental data technological scheme of vinyl acetate preparation by catalyst acetylating of acetylene was offered
