低压下甲醇气相羰基化合成醋酸催化剂国外正在大力探索,然而对反应动力学的研究却极少,仅见1972年K.K.Robinson等报导过一篇铑络合物/活性炭催化剂上甲醇羰基化的反应动力学研究结果,他们的结论是低压下甲醇气相羰基化的反应与均相反应类似,郎反应速度与碘甲烷浓度的一次方成正比,而与甲醇和一氧化碳浓度无关。 我们在常压下甲醇气相羰基化催化剂探索的基础上,进行了反应规律的考察,本文总结的是在RC5-7催化剂上常压下甲醇气相羰基化的反应动力学初步研究结果。
Under low pressure gas phase carbonylation of methanol synthesis of acetic acid catalyst is vigorously explored abroad, however, the kinetics of reaction research is rare, only KKRobinson et al reported in 1972 a rhodium complex / activated carbon catalyst methanol carbonylation reaction kinetics As a result, they concluded that the gas phase carbonylation of methanol at low pressure is similar to the homogeneous reaction, with the Lang reaction rate proportional to the first-order of methyl iodide concentration, regardless of methanol and carbon monoxide concentrations. Based on the exploration of methanol vapor-phase carbonylation catalyst at atmospheric pressure, we investigated the reaction law. This paper summarizes the preliminary kinetic kinetics of gas-phase carbonylation of methanol over RC5-7 catalyst under atmospheric pressure.
