- W2365057811 abstract "The synthesis of ethylidene diacetate and its thermocracking reaction to vinyl acetate are two key steps in preparation of vinyl acetate from C_1 compound (methanol and syngas). Zinc chloride and (anhydrous) benzene sulfuric acid showed good catalytic activity for these two reactions. And the whole (reaction) system's mechanism is proposed using the organic intermediate theory. Through analyzing the (reaction) mechanism under the action of electrophile proton (H~+), it is proposed that the rate controlling step in ethylidene diacetate's thermocracking reaction is the breaking of alkoxy in ethylidene diacetate molecule. The rate of reaction introduced from reaction mechanism model is proportional to the concentration of ethylidene diacetate. And the reaction kinetics experiment is conducted on a tubular reactor equipped with multi-sampling tap equipment. The reaction rate is also proportional to the concentration of ethylidene (diacetate.) The kinetics equation is as the following:-dC_(EDA)dt=7.008×10~(10)exp-97 169RTC~(1.008)_(EDA)C~(0.502)_(VAc)1-J_cK_c.So, the mechanism rate model is agreed with the kinetics experiment." @default.
