摘要:
The invention relates to a method for producing 1,2-dodeca-2,10-diene diacid and 1,12-dodecanoic acid whereby cyclooctene 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 unsaturated dicarboxylic acid being precipitated and being hydrated in a second reaction step.
