Title
Microencapsulated ruthenium catalyst for the hydroformylation of 1-hexene
Abstract

A ruthenium complex [Ru(CO)3Cl2]2 microencapsulated into poly(4-vinylpyridine) (P4VP) cross-linked with 25% divinylbenzene (DVB) was developed as a new catalyst for the hydroformylation of 1-hexene. The highest catalytic activity with the 93% total conversion, and with yields of 44% aldehydes and 26% alcohols was achieved at 423 K. Typically, the polymer capsules are used at temperatures below 373 K. The DVB cross-linked P4VP capsules were, however, thermally stable at 423 K and could be recycled at least four times with moderate loss of catalytic activity. The catalysts were characterized by SEM, ICP-MS, and FT-IR.
