    • Abstract


      Water-soluble meta sulphophenyldiphenylphosphine complex of rhodium preparedin situ catalyses the homogeneous hydrogenation of fumaric, maleic and crotonic acids in water and 1:1 water-methanol mixture as solvents. Fumaric acid gives a higher rate of hydrogenation than maleic acid. Rate of hydrogenation also increases on changing the solvent from pure water to 1:1 mixture of methanol and water. Rate law for the reaction has been proposed.
