Paragraph 0027-0038, (2019/12/02)
The invention provides a method for preparing succinate by double carbonylation of acetylene. Acetylene, carbon monoxide and an alcohol compound are used as raw materials and subjected to the double carbonylation reaction in a solvent under the catalysis of a catalyst, and the succinate compound is obtained. The catalyst is composed of a palladium compound, a lithium halide/acid auxiliary agent and a nitrogen-oxygen ligand, wherein the nitrogen-oxygen ligand is one or more of 2-hydroxypyridine, 3-hydroxypyridine and 2-picolinic acid, and the dosage of the catalyst is 0.0001-1.0% of the total weight of the reaction system; in the reaction system, the molar ratio of acetylene to the alcohol compound is 1:(2-16), and the molar ratio of the alcohol compound to the solvent is 1:(7-35). According to the method, the succinate compounds can be produced by a one-pot method, wherein the process is simple, and the investment cost of an industrial device is low; the reaction conditions in the production process are mild, the catalytic activity of the catalyst is high, the stability is high, the service life is long, the yield can reach 90% or above, and the higher technical competitive advantage is achieved.
