  A catalytic process for preparing an α,β-ethylenically unsaturated carboxylic acid salt, comprising a) contacting an alkene and carbon dioxide with a carboxylation catalyst, an organic solvent, and an alkoxide having a secondary or tertiary carbon atom directly bound to an [O-] group, to obtain a crude reaction product comprising the α,β-ethylenically unsaturated carboxylic acid salt and an alcohol by-product which is the conjugate acid of the alkoxide, b) allowing the α,β-ethylenically unsaturated carboxylic acid salt to precipitate out from the crude reaction product; and c) subjecting at least part of the crude reaction product to a mechanical separation step while maintaining the alcohol by-product in liquid form to obtain a solid phase comprising the α,β-ethylenically unsaturated carboxylic acid salt and a liquid phase comprising the carboxylation catalyst, the organic solvent and the alcohol by-product. The process allows for easy separation of the α,β-ethylenically unsaturated carboxylic acid salt by a mechanical separation operation.

  一种制备α，β-乙烯基不饱和羧酸盐的催化过程，包括a）将烯烃和二氧化碳与羧化催化剂、有机溶剂和直接与[O-]基团相结合的二级或三级碳原子的烷氧基接触，以获得包含α，β-乙烯基不饱和羧酸盐和醇副产物的原始反应产物，该醇副产物是烷氧基的共轭酸，b）使α，β-乙烯基不饱和羧酸盐从原始反应产物中沉淀出来；c）在保持醇副产物处于液态的情况下，对至少部分原始反应产物进行机械分离步骤，以获得包含α，β-乙烯基不饱和羧酸盐的固相和包含羧化催化剂、有机溶剂和醇副产物的液相。该过程允许通过机械分离操作轻松分离α，β-乙烯基不饱和羧酸盐。
