Abstract
A number of nitrogenous derivatives of cyclized acids derived from C‐18, triene‐containing fatty acid sources, were prepared. Mixed amides (mp 33C), nitriles (fp 蜢25C), and amines (fp 蜢34C), prepared from the hydrogenated cyclic acids, have uniquely low mp for fat‐derived substances of their mol wt. Compatibility with synthetic resins and solubility in organic solvents of the mixed amides are high compared to common fatty‐amide mixtures. The nitriles and morpholides are compatible with polyvinyl chloride and may have potential as plasticizers for it. The hydrogenated cyclic fatty acid amines have an approximate fp of 蜢34C. The diethanolamides, ethenoxylated amides, and quaternary amines were prepared and their surface‐active properties compared with similar fat‐derived substances.
