"PROCESS FOR SEPARATING FATTY ACIDS" ABSTRACT This invention comprises a process for separating oleic acid from a feed mixture comprising an oleic acid and linoleic acid, which process comprises contacting the mixture at separation condition with a molecular sieve comprising silicalite, thereby selectively retaining the oleic acid. The oleic acid may be recovered from the molecular sieve by displacement with a displacement fluid. The feed mixture may also contain rosin acids in which case a first molecular sieve comprising silicalite is used to separate the fatty acids from the rosin acids. It is preferred that the displacement fluid comprise a liquid having a minimum polarity index and that the molecular sieve comprise silicalite dispersed in a silica matrix.
