The invention relates to a method for producing α/β-unsaturated dicarboxylic acids and the corresponding saturated dicarboxylic acids, whereby the corresponding cycloalkene and acrylic acid are reacted with a ruthenium catalyst by way of a metathesis reaction at high substrate concentrations until the reaction takes place in substance, the resulting dicarboxylic acid being precipitated.
该发明涉及一种生产α/β-不饱和二羧酸和相应的饱和二羧酸的方法,其中通过一种交换反应,在高底物浓度下,将相应的环烯烃和丙烯酸与钌催化剂反应,直到反应在物质中发生,生成的二羧酸被沉淀。
