Abstract
The essence of the process of synthesis of vinyl acetate from acetylene is the production of vinyl acetate from acetylene and acetic acid in the presence of zinc acetate catalyst in the vapor-gas phase in the static catalyst layer.Numerous studies on the synthesis of vinyl acetate in the vapor phase have been published, the process is carried out at atmospheric pressure in the range of 170-230 ° C, acetylene: acetic acid mole ratio in the presence of zinc acetate ingested on activated carbon. Replacement of zinc acetate with partial or complete cadmium acetate leads to an increase in catalyst activity. K2Cr2O7 (2% relative to catalyst mass) is used as a promotional additive.Sensitive elements were installed to measure the temperature at three points along the height of the reactor and catalyst layer to measure the exothermic reaction heat. In the experiments, the ratios of the initial components were changed within the limits that provide low conversion of the given component in a stoichiometrically low amount.
