ABSTRACT:
Octene-1 is difficult to separate from several of its isomers by conventional distillation or rectification because of the closeness of their boiling points. Octene-1 can be readily separated from its close boiling isomers by azeotropic or extractive distillation. Effective agents are: for azeotropic distillation, t-amyl methyl ether; for extractive distillation, isophorone.
