POLYBETAINE-STABILIZED, PALLADIUM-CONTAINING NANOPARTICLES, A PROCESS FOR PREPARING THEM AND ALSO CATALYSTS PREPARED FROM THEM FOR PRODUCING VINYL ACETATE

摘要

Polybetaine-stabilized, palladium-containing nanoparticles, a process for preparing them and also catalysts prepared from them for producing vinyl acetate The invention relates to soluble nanoparticles which comprise palladiumalone or palladium together with metals of subgroups Ib and VIIIb of the periodic table and which are embedded in protective colloids, wherein the protective colloids comprise at least one polymer having betaine groups, and to a process for preparing them. The soluble nanoparticles are suitable for the preparation of catalysts.
