Cymenes. 1. Modern state of processes for producing cymenes

Abstract

The article analyzes methods for the preparation of cymenes based on using petrochemical raw materials: toluene and propylene/isopropanol. It is concluded that at present advanced technologies for the production of individual cymenes are absent, and the heterogeneous catalytic processes require significant improvement.
