PROCESS FOR SEPARATING A CARBOXYLIC ACID OF 1-8 CARBON ATOMS FROM A MIXTURE THEREOF WITH WATER AND/OR ONE OR MORE OTHER OXYGENATED ALIPHATIC COMPOUNDS

摘要

This invention relates to a process for separating carboxylic acids from a mixture thereof with water or one or more other oxygenated aliphatic compounds by adsorption over a zeolite or silicalite followed by desorption. The zeolite used preferably has a silica to alumina ratio greater than 50:1.
