UNIDYME T-18 dimer acid is dimerized fatty acid produced by selective reaction of high
quality, tall oil fatty acid distillates.
It is mainly composed of very hydrophobic C36 dicarboxylic acids and C54 tricarboxylic acids. The carboxylic groups and double-bond unsaturation of UNIDYME T-18 undergo many chemical reactions to form a wide variety of chemical intermediates.
The most common reactions of the carboxyl group are amidation, esterification, reduction, saponification, ethoxylation, and acid chloride formation.
The common reactions on the double bond are epoxidation, hydrogenation, sulfation, sulfonation, sulfurization and halogenation. |
