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 phosphorus modified alumina matrix, the precursor of the molecular sieve comprising silicalite powder dispersed in an alumina hydrosol commingled with a phosphorus containing compound, the phosphorus to aluminum molar ratio in the molecular sieve being from 1:1 to 1:100. The fatty acid is selectively retained. The fatty acid is recovered from the molecular sieve by displacement with a displacement material comprising an organic acid.
