Abstract
1. A study was made of the transformations of m-xylene in presence of aluminum halides and also in presence of Sn, Ti, Sb, and Zn chlorides and their equimolecular mixtures with aluminum chloride. 2. It was shown that in presence of AlCl3 or AlBr3 m-xylene undergoes isomerization with formation of 18–20% by weight of p-xylene. This yield is 75.6–85.2% of the equilibrium value. 3. It was found that addition of SbCl3 or SnC4 to aluminum chloride results in suppression of the drastic effects of aluminum chloride alone with almost complete elimination of side reactions of demethylation and methylation.
