"PROCESS FOR SEPARATING SATURATED FATTY ACIDS" ABSTRACT OF THE DISCLOSURE A process for separating a first saturated fatty acid from a second saturated fatty acid contained in a feed mixture comprising the acids, the chain length of the first being at least two carbon atoms greater than that of the second. The process comprises contacting the feed mixture at adsorption conditions comprising a crystalline silica having a silica to alumina mole ratio of at least 12, thereby selectively adsorbing the first saturated fatty acid. The remainder of the feed mixture is then removed from the adsorbent, and the first acid recovered from the adsorbent by desorption at desorption conditions with a desorbent liquid soluble in the feed mixture and having a polarity index of at least 3.5.
