A process for the selective production of methanol comprising contacting a mixture of hydrogen and carbon monoxide with a catalytic amount, sufficient to catalyze the reaction, of lanthanum rhodate having a perovskite structure, wherein the hydrogen to carbon monoxide mole ratio is from 20:1 to 1:20 and the reaction is carried out at a pressure of from 100 psig to 15000 psig and a temperature of from 150.degree. C. to 450.degree. C.
