UNSATURATED DICARBOXYLIC ACIDS FROM UNSATURATED CYCLIC HYDROCARBONS AND ACRYLIC ACID BY WAY OF METATHESIS, THE USE THEREOF OF AS MONOMERS FOR POLYAMIDES, POLYESTERS AND POLYURETHANES, AND SUBSEQUENT REACTION TO DIOLS AND DIAMINES

摘要

The invention relates to a method for producing α,ß-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.
