Abstract: Catalyst for carrying out heterogeneous catalytic chemical reactions. The catalyst is a composite comprising a solid carrier and at least one sulfonic acid with at least two sulfonic groups per molecule. The catalyst is prepared by impregnating a solid carrier with at least one sulfonic acid of the kind specified and the resulting product is dried and baked and, if desired, steamed in an inert gas stream. Examples of catalytic reactions that are successfully carried out with such a catalyst are the production of alcohols by hydration of olefins and the production of ethers by dehydration of alcohols.

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 DEG 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 DEG C and baking the so dried product at 170 DEG to 330 DEG . 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.
