ABSTRACT:
This invention comprises a process for separating a fatty acid from a mixture comprising a fatty acid and a rosin acid, which process comprises contacting the mixture at separation conditions with a molecular sieve comprising silicalite, thereby selectively retaining the fatty acid. The fatty acid is recovered from the molecular sieve by displacement with a displacement fluid comprising an aqueous solution of a ketone from the group comprising acetone, methyl-ethylketone, or di-ethylketone.
