Introduction and market application of dimeric acid

The binary carboxylic acid generated by the reaction of two or more C18 unsaturated fatty acids is called dimeric acid. Dimeric acid is a kind of chemical with special physical and chemical properties, which is widely used in industry. It plays an increasingly important role in the production of printing ink, coatings, adhesives, lubricants and surfactants. Commercial dimeric acid is a mixture mainly composed of C36 dicarboxylic acid, which contains some trimer C54 and higher oligomer, and also contains a small amount of saturated, unsaturated and isomerized monomer acid C18. The early commercial dimeric acids were made from a variety of unsaturated fatty acids (such as flaxseed oil, soybean oil, cottonseed oil fatty acids) or their methyl esters by thermal dimerization. The research conducted by the Northern Research Institute of the Department of Agriculture in Peoria, Illinois, laid a foundation for this process. In 1948, American Emert Company began to produce dimeric acid on a large scale by thermal polymerization. Soon, clay catalyzed dimerization replaced thermal dimerization to produce dimeric acid with better quality, and tall oil fatty acid was used as raw material; Since then, the clay catalytic process has been continuously improved, and other catalytic processes have emerged one after another.
