Abstract: A chromatographic process able to separate para-xylene from C.sub.8 isomers and C.sub.9 aromatics. In the process, the para-xylene-containing feed mixture is contacted with an X or Y zeolite adsorbent having Group IA or IIA cations, e.g., barium and/or potassium at exchangeable cationic sites. The para-xylene is selectively adsorbed onto the adsorbent. The feed is then removed from the adsorbent and the para-xylene recovered by desorption with diethyltoluene. The C.sub.9 's and the other xylene isomers in the raffinate, can be separated from this heavy desorbent by fractionation of the raffinate and the desorbent recycled to the process. The preferred desorbents are 2,3-diethyltoluene, 2,5-diethyltoluene and 2,6-diethyltoluene.

Abstract: Industrial grade chloroform is purified to remove traces of cis-1,2-dichloroethylene, bromochloromethane, and amylenes by a two-step process. The chloroform is first treated by contacting with aqueous sulfuric acid to remove amylenes and thereafter passed over a zeolite having an average pore size of 3 to 6 Angstroms and a Si/Al atomic ratio in the range of about 1.6/1 to 3/1, preferably calcium chabazite, to remove cis-1,2-dichloroethylene and bromochloromethane.
