ABSTRACT:
Linoleic acid cannot be separated from linolenic acid by distillation or rectification because of the closeness of their boiling points. Linoleic acid is readily separated from linolenic acid by azeotropic distillation. Effective agents are nonane, dimethyl formamide, 2-nitropropane and pentyl propionate.
