Abstract Modified catalysts by ion exchange with HZSM-5 zeolite were used for the catalytic amination of isobutene. The effect of introduction B、Ga atom to the zeolite on the activity of catalyst were investigated by means of differential reaction. and the the influence of hybrid atom on the acidity of zeolite were examined by NH3-TPD technique.
Key words HZSM-5, Isobutene, Amination
