Process for the removal of short chain fatty acids from aqueous glycerol solutions
摘要
<p>Short-chain (4-10C) fatty acids (I) are removed from aqueous glycerol solutions (II) by passing (II) through a pump feed tank into a filtration unit to give glycerol solution as permeate and a (I)-containing retentate which is returned to the feed tank, so that the solubility limit for (I) is exceeded, (I) separates from the water and is removed from the tank.</p>
