The fat acids of American tall oil

  • Published:
Oil & Soap

Summary

The composition of the fat acids of six samples of American tall oil has been determined. They are all quite similar in fat acid composition. The average values were: linoleic acid 48%; oleic acid 45%; saturated acids 7%. There is present approximately 11% of conjugated linoleic acid, probably formed by the action of alkali and heat during the cooking of the pulp from which the tall oil was formed.

Detailed fractional distillation of a sample of the methyl esters of the fat acids showed that the saturated acids are mostly palmitic, that there may be about 1% of palmitoleic, and that the conjugated linoleic acid present can be separated and concentrated by fractional distillation.
