CATALYTIC ACETYLATION OF ACETYLENE IN VAPOR PHASE

H.M. Nasimov, N.I. Fayzullayev


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
