Abstract
Catalyst for carrying out heterogeneous catalytic chemical reactions. The catalyst is a composite comprising a solid carrier and at least one member of the group of carboxymethane sulfonic acid and products resulting from the thermal treatment thereof at a temperature not exceeding 350.degree.C. The catalyst is prepared by impregnating the carrier carboxymethane sulfonic acid or a precursor or precursors thereof, drying the impregnated carrier at a temperature not exceeding 170.degree.C and baking the so dried product at 170.degree. to 330.degree.. Examples of catalytic reactions that are successfully carried out with such a catalyst are production of alcohols by hydration of olefins, production of esters from acids and olefins, production of esters from alcohols and alkylation of aromatic hydrocarbons.
