An oleic acid containing adduct is produced by reacting tall oil fatty acid (which contains pre-conjugated linoleic acid) with a dienophile at a temperature between 180.degree. C. and 300.degree. C. No catalyst or solvent is necessary for the reaction to occur. The adduct is subsequently distilled to yield a high-purity, light color oleic acid.

Process for making high-purity oleic acid

Solvent-borne alkyd resin compositions are disclosed comprising a 21-carbon dicarboxylic acid. Substitution of the dibasic carboxylic acid component of the composition with this 21-carbon dicarboxylic acid permits a reduction in the viscosity of the resin without decreasing the average molecular weight of the resin.

Sovlent-borne alkyd resin compositions

A 21-carbon aliphatic branched chain dicarboxylic acid is produced by reacting pre-conjugated fatty acid (which contains linoleic acid) with acrylic acid at a temperature between 180.degree. C. and 300.degree. C. No catalyst or solvent is necessary for the reaction to occur. The reaction product is subsequently distilled to yield high purity dicarboxylic acid.
