Abstract: PP-42 Окислительное метилирование бензола метаном на цеолите ZSM-5 в присутствии закиси азота Conversion of the CH4-C6H6-N2O feed on a series of H-Na-ZSM-5 catalysts leads to complex mixture of C1-C2-substituted alkylaromatics (toluene, xylenes, trimethylbenzenes, derivatives of indene, naphtalene and diphenylmethane) and hydroxylated hydrocarbons (phenol and cresols ). It was shown that acidity of the surface favored the progress of reaction of oxidative methylation and did not change the rate of hydroxylation. Composition of the product obtained under the same condition on H-Na-ZSM-5 using different feeds (CH3OH, CH4-N2O, C6H6-N2O, CH3OH-C6H6) is compared with that for CH4-C6H6-N2O feed, and reaction routes for hydroxylation and methylation processes are discussed.
