Hydrogenation of carbon dioxide in the presence of rhodium catalysts

摘要

The results of CO_2 hydrogenation in the presence of the Wilkinson complexes,viz.,RhCl_3 and acacRh(CO)_2,at room temperature and excess PPh_3 are presented.The influence of different ions on the catalytic properties of the Rh complexes was studied.Methanol and methyl formate are formed along with formic acid in the presence of an inorganic salt.Ions that are the most active in the formation of formic acid are the least active in methanol formation.
