PROCESS FOR THE PRODUCTION OF PSEUDOCUMENE OR DURENE

摘要

A process for producing pseudocumene or durene is described, comprising methylating xylene by the use as a catalyst of a crystalline borosilicate. The specific crystalline silicate catalyst increases the conversion of xylene and the selectivity of pseudo-cumene or durene. The process of the invention can be performed either in one step or in two steps. The two-step reaction provides various industrial advantages, such as a high degree of utilization of the methylating agent and a great increase in the selectivity of the product.
