Abstract: This invention comprises a process for separating 2,4-toluene diisocyanate from a feed mixture with 2,6-toluene diisocyanate. The process comprises contacting the mixture at adsorption conditions with an adsorbent comprising a Y-type zeolite cation exchanged with a cation in the group Na, Ca, Li or Mg, thereby selectively adsorbing the 2,4-toluene diisocyanate. The remainder of the feed mixture is removed from the adsorbent and the adsorbed toluene diisocyanate isomer is recovered by desorption at desorption conditions with a desorbent material comprising toluene.

Abstract: Methods have been found to prepare fused silica capillary gas chromatographic columns where the stationary phase is a molecular sieve affixed to the silica capillary wall without the aid of an organic binder by modifying the interior surface of the silica prior to contact with the molecular sieve. These totally inorganic columns greatly expand the application and range of gas chromatographic separations and allow the use of non-traditional carrier gases, even air, while not degrading the separation of components. The columns are films of small molecular sieve particles affixed to a silica surface modified by such treatments as hydrogen peroxide, alumina deposition, or silica deposition followed by fixation at 80.degree.-160.degree.

Abstract: In the process flow scheme for chromatographically separating para-xylene from C.sub.8 isomers containing substantial amounts of C.sub.9 aromatic hydrocarbon impurities with BaX or KY zeolite adsorbent and heavy desorbents, e.g., tetralin and diethyltoluene, a bottoms stream from the extract fractionation column containing desorbent is recycled to the separation unit and a sidecut stream, containing C.sub.9 aromatic hydrocarbon impurities and a minor amount of the desorbent from the raffinate stream, is directed to the raffinate fractionation column, thereby removing C.sub.9 aromatic hydrocarbons from the desorbent before recycling the desorbent to the separation unit, and preventing C.sub.9 aromatics from building up in the desorbent input. A fractionator for the extract column bottoms stream is eliminated, lowering capital costs, and energy requirements for the raffinate column are reduced.

Abstract: A chromatographic process able to separate paraxylene 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 while maintaining the water content of the adsorbent at about 4.2-6% (LOI). The para-xylene components are selectively adsorbed onto the adsorbent. The non-adsorbed feed is then removed from the adsorbent and the para-xylene recovered by desorption with tetralin or alkyl derivatives of tetralin. 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.

Abstract: A chromatographic process able to separate para-ethyltoluene from feed mixtures of C.sub.8 and/or C.sub.9 aromatic hydrocarbons. In the process, the para-ethyltoluene-containing feed mixture is contacted with a Y zeolite adsorbent having potassium at exchangeable cationic sites. The para-ethyltoluene is selectively adsorbed onto the adsorbent. The non-adsorbed components of the feed are then removed from the adsorbent and the para-ethyltoluene recovered by desorption with tetralin or alkyl or dialkyl derivatives of tetralin or alkyl derivatives of naphthalene. The other C.sub.9 's and the xylene isomers in the raffinate and p-ethyltoluene in the extract can be separated from the heavy desorbent by fractionation of the raffinate or extract and the desorbent recycled to the process.
