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 a crystalline silica, thereby selectively retaining the fatty acid. The fatty acid is recovered from the molecular sieve by displacement with a displacement fluid comprising an ester containing less than six carbon atoms per molecule. Once the rosin acid is removed from the feed mixture, the process is also effective in separating the fatty acids from each other, using the same molecular sieve and displacement fluid.
