Abstract  

A novel rhodium-containing diphenylphosphinate copolymer of styrene ad divinylbenzene (used as catalyst for methanol carbonylation) was prepared and studied by means of thermoanalytical methods. Simultaneous TG-DTA experiments were run to assess the effect of the grafting procedure on the thermal behaviour. Additional information concerning the structural modifications observed was obtained by infrared spectroscopy. On the basis of the collected evidences the cited catalysts were found to be stable up to 250C in the presence of nitrogen and thereafter progressive degradation took place. Such high thermal stability is consistent with the experimental conditions used (T=230C, PCO+H2 = 210 bar) for the recently reported methanol carbonylation promoted by iodomethane which leads to a mixture of C2-C6 carboxylic acids.
