DOCUMENT TYPE: Patent CA Section: 45 (Industrial Organic Chemicals, Leather, Fats, and Waxes) Section cross-reference(s): 25 Toluene [108-88-3] and/or o-chlorotoluene [95-49-8] is chlorinated with Cl in the presence of a zeolite catalyst to give dichlorotoluene (I) [29797-40-8], I is photochem. chlorinated to give dichlorobenzyl chloride (II) [38721-71-0], and II is subjected to a Friedel-Crafts reaction with I in the presence of a zeolite catalyst to give tetrachlorodiarylmethanes having good dielec. properties (esp. dipole moments). The zeolite is a decationized faujasite X or Y which gives good selectivity to dichlorides in the 1st step of the prepn. No special treatment is necessary to remove or destroy the zeolite catalysts.

DOCUMENT TYPE: Conference CA Section: 45 (Industrial Organic Chemicals, Leather, Fats, and Waxes) The sepn. of a mixt. of o-chlorotoluene [95-49-8] and p-chlorotoluene [106-43-4] was performed through adsorption on 13X zeolites using PhMe [108-88-3] desorbent. A math. model of adsorber dynamics was developed. The influence of desorbent characteristics on the sepn. process efficiency was also investigated.
