ABSTRACT:
The present invention is directed to compositions of specific carboxylic acid, fatty acid or oil derivatives containing nitrile groups and methods of their preparation. The preparation involves a hydrocyanation reaction. A method of hydrgenating the nitrile containing carboxylic acid acids obtained by above hydrocyanation to produce amine containing carbixylic acids is also disclosed in this invention.
