Chemistry, Physics and Technology of Surface| Резюме: | Na- and K-forms of zeolite X have been determined to be the most selective in toluene with methanol alkylation toward styrene. It has been shown that KX, RbX і CsX impregnated with cesium nitrate as opposed to the sample NaX leads to improvement in the aim reaction selectivity. The selectivity changing is explained by altering the ratio of catalyst acid and base characteristics. It is concluded that catalyst' basic function in the reaction studied is defined by additional cesium compounds, while the nature of ion-exchange cations determines primarily the acid is component of activity. |
