Patent number: 4578223Abstract: 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.Type: GrantFiled: October 9, 1984Date of Patent: March 25, 1986Assignee: UOP Inc.Inventor: Michael T.

Patent number: 4524030Abstract: 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.Type: GrantFiled: October 7, 1983Date of Patent: June 18, 1985Assignee: UOP Inc.Inventors: Michael T. Cleary, Santi Kulprathipanja, Richard W. Neuzil
