| Dimer Acid |
 |
UNIDYME M-35 is dimerized fatty acid produced by selective reaction of high-quality tall oil fatty acid distillates mainly composed of C36 dicarboxylic and C54 tricarboxylic acids.
The carboxyl groups and double-bond unsaturation of UNIDYME M-35 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. |
