Abstract
A method of separating 1,4 cineole from a mixture containing 1,4 and 1,8 cineoles wherein the mixture is contacted with a zeolite having a constraint index of from 0.2 to 12 and having port sizes of approximately 6.7-7.0 angstroms. This causes the 1,4 cineole to be sorbed into the zeolite while the 1,8 cineole is excluded. The zeolite is then separated from the 1,8 cineole so that the 1,4 cineole may be desorbed from the zeolite. This desorbtion may be accomplished by heating the zeolite to a temperature above the boiling point of the cineole or by liquid phase displacement.
