Usually we get recemic mixture of alpha , beta & gama ionone, when we synthesize the beta-ionone in any method (cyclization).
Is there any easy method to seperate beta-ionone from the mixture of products?
Ar,
you may find an answer to your Q in the following :
--- Fumio Toda1, Koichi Tanaka and Takaji Fujiwara, Isolation of Conformational Isomers of α- and β-Ionones by Inclusion Complex Formation, Angewandte Chemie International Edition in English, Volume 29, Issue 6, pages 662–664, June 1990.
Or site and references cited therein

Good luck

It's not mine
As the difference in boiling points are about 38 C (alpha 237-238 C, beta 275-276 C), one can easily separate the alpha from the beta by fractional distillation.
Do the recrystallisation if your compound is solid beta will get solid and alfa goes in to Mls
