Analysis of factors affecting yield of 2-propylheptanol production
2-propylheptanol is an important deep-processing product of C4 component in coal-based methanol to olefin plant,and its product yield and output volume are directly related to the economic benefits of the enterprise.The production process of 2-propylheptanol in China Energy Baotou Coal Chemical Co.,Ltd.was introduced.Also,the influence of the following factors on the yields and output volumes of intermediate products valeraldehyde,2-propylheptanal and final product 2-propylheptanol was analyzed,including the composition of mixed C4 components,the partial pressure of CO and catalyst concentration in the process of carbonyl synthesis of valeraldehyde;the reaction temperature,residence time and alkali concentration in the condensation process,and the reaction temperature and hydrogen mass in the hydrogenation process.Through the above analysis and targeted optimization and adjustment of operating parameters,the yield and output volume of 2-propylheptanol could be continuously improved.
