Abstract

1503642 Catalytic reactions HOECHST AG 2 July 1975 [6 July 1974] 27838/75 Heading B1F In the process for carrying out heterogeneous catalytic reactions continuously in liquid phase as disclosed in specification 1363245. the catalyst is a palladium catalyst deposited on a silica carrier which is obtained by contacting a mixture of pulverulent silica carrier and in homogeneous silica particles with upward flowing water to free the carrier from the silica particles. The expression "inhomogeneous silica particles" is defined as meaning silica particles having a porosity which differs substantially from that of the other particles in the mixture. Such particles consist mainly of the fines present in the mixture. The silica carrier has a particle size of 20-300 microns and the catalyst may be produced by impregnating the carrier with a palladium salt which is subsequently reduced to metallic palladium in accordance with the process described in Specification 1403293.
