Title:
POLYMER-SUPPORTED 4-(N-BENZYL-N-METHYLAMINO)PYRIDINE CATALYST AND PROCESS FOR SAME
Document Type and Number:
WIPO Patent Application WO1990003368
Kind Code:
A3
Abstract:
A cross-linked polymer-supported 4-(N-benzyl-N-methylamino) pyridine material and process for its preparation in high yield and having effective physical and catalytic properties. The polymer-supported catalyst is characterizd by the suspension copolymerization of an organic phase containing the corresponding vinyl-substituted pyridine monomer, a styrene monomer, and a suitable cross-linking agent and free radical-generating catalyst in the presence of an aqueous phase containing a cellulose ether derivative as the stabilizing agent. The catalyst is further characterized by its yield in excess of 90% by weight and by its predominant and generally spherical and smooth bead form and substantially uniform size that is efficiently hard and durable and possesses sufficient catalytic activity for effective use in acylation, alkylation or other related reactions.
