A study of the kinetics of vinyl acetate synthesis

Catalytic Reactions of Acetylene: A Feedstock for the Chemical Industry Revisited

“…Like many other reactions of acetylene, this reaction has not received much interest from the academic community during the last 50 years. Several kinetic studies have been published, and they suggest that with increasing temperature the rate-limiting step changes from acetylene adsorption at low temperature through an intermediate temperature window to acetic acid adsorption at high temperature . With a mixture of deuterated acetic acid (CD 3 COOH) and acetylene it was shown that undeuterated vinyl acetate is formed first and that the formation of deuterated vinyl acetate starts only after a period of time, indicating that acetate anions are first removed from the catalyst by reaction with acetylene and afterward regenerated by acetic acid from the gas phase …”

A Highly Active In Situ Zn(CH3COO)2-NC Catalyst for the Acetoxylation of Acetylene

“…Under certain reaction conditions, the conversion could reach 22.6%. In the area of software simulation and reaction mechanism research, many works have been devoted to areas such as specific reaction paths for acetylene acetoxylation, active sites, adsorption of raw materials, the influence of functional groups on the reaction on the carrier, and the simultaneous occurrence of side reactions. − …”

Parametric sensitivity in fixed‐bed reactors: Inter‐ and intraparticle resistance

“…That work studied vinyl acetate synthesis catalyzed by zinc acetate supported on activated carbon. A previous detailed kinetic study (El-Sawi et al, 1977) showed that this reaction follows firstorder kinetics, with dimensionless activation energy y = 20 at the wall temperatures examined in the sensitivity experiments.…”
