A procedure for the preparation of o-tolualdehyde from o-toluanilide by the Sonn-Miiller method has been published in Organic Syntheses. In addition to the alternative methods of preparation listed there, o-tolualdehyde has been prepared from o-xylyl bromide and hexamethylenetetramine, by the Stephen reduction of o-tolunitrile, and by the procedure of the present preparation. ...

Isomerization of xylenes is always coupled with separation processes. In most cases, p-xylene is removed from the reaction mixture by crystallization or selective adsorption. The recovered o-/m-xylene mixture, in turn, is usually recycled for reequilibration. Because of cost of separation, the highly selective carbonylation of toluene to p-tolualdehyde gained significance. Subsequent reduction gives p-xylene. [Pg.194]
