摘要：
Effects of alkali metal halides promoter on the oxidative methylation of toluene with methane over KY zeolite catalysts were systematically studied. In terms of the catalytic activity for the oxidative methylation of toluene with methane over those catalysts, the following order was observed: NaBr/KY>KBr/KY>NaCl/KY. The C-8 products containing much styrene were gained over alkali metal bromide promoted KY zeolite catalysts. The acidity and basicity of these catalysts were studied by using NH3-TPD and formic acid-TPD. (C) 1999 Elsevier Science B.V. All rights reserved.
