Abstract
A process for separating oleic acid from linoleic acid contained in a feed mixture comprising said acids, characterized in that the feed mixture is contacted at separation conditions with a molecular sieve substantially free from hydroxyl groups and comprising silicalite in a silica matrix, thereby selectively retaining the oleic acid, the linoleic acid is removed from the oleic-acid-containing molecular sieve, and thereafter the oleic acid is recovered from the molecular sieve by displacement with a displacement fluid at displacement conditions. (18pp) EPAB- EP-134357 B A process for separating oleic acid from linoleic acid contained in a feed mixture comprising said acids, characterized in that the feed mixture is contacted at separation conditions with a molecular sieve substantially free from hydroxyl groups and comprising silicalite in a silica matrix, thereby selectively retaining the oleic acid, the linoleic acid is removed from the oleic-acid-containing molecular sieve, and thereafter the oleic acid is recovered from the molecular sieve by displacement with a displacement fluid at displacement conditions.
