ABSTRACT:
This invention comprises a process for separating a saturated fatty acid from a feed mixture comprising saturated and unsaturated fatty acids, which process comprises contacting the mixture at separation conditions with a molecular sieve comprising a crystalline silica, thereby selectively retaining the saturated fatty acid. The saturated fatty acid is recovered from the molecular sieve by displacement at displacement conditions with a displacement fluid comprising a diluent soluble in the feed mixture and having a polarity index of at least 3.5. Amorphous silica is a preferred binder for the molecular sieve.
