Title:
シクロオクテンとアクリル酸との開環交差メタセシス(ROCM)による、ドデカ-2,10-ジエン-1,12-ジカルボン酸又は1,12-ドデカンジカルボン酸の製造方法
Document Type and Number:
Japanese Patent JP2011521920
Kind Code:
A
Abstract:
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.
