The coupled reaction of methyl acetate and n‐hexane was carried out over a HZSM‐5 *** addition to a thermal coupling effect,systematic variations in the product distribution were also observed in the coupled *** bezene‐toluene‐xylene(BTX)selectivity was remarkably improved while the H2,CO,and CO2 selectivity *** deactivation of the catalyst was observed,caused by the extremely high reactivity of methyl acetate,which was alleviated after adding n‐*** results indicated that a coupling effect exists in this system.A detailed pathway for the coupled system is suggested based on the analysis of the surface species,carbonaceous species deposited on the catalyst,as well as the product selectivity *** good match between the"hydrogen deficiency"of methyl acetate and the"hydrogen richness"of n‐hexane is consistent with the observed coupling effect.

The target production were obtained by coupled reaction of 3-amino-5-nitro-2, 1- benzoisothiazole,as a diazo component,with some derivatives of anilline or some derivatives of naphthylamine sulfonic acid in proper condition. Their colors are from red to violet. They have excellent tight property. The chemical and physical test of production verified that they were some unique properties.
