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 in a silica matrix the precursor of the molecular sieve comprising silicalite powder dispersed in colloidal amorphous silica, the precursor having been gelled and then treated in a manner to substantially eliminate hydroxyl groups from the molecular sieve, thereby selectively retaining the fatty acid. The fatty acid is recovered from the molecular sieve by displacement with a displacement material comprising an organic acid.
