Abstract
Process for hydrogenolysis of an alkali metal or an alkaline earth metal salt of formic acid so as to produce methanol and a metal hydroxide corresponding to the formic acid salt wherein a catalyst of cobalt, rhenium, ruthenium, palladium, platinum or mixtures thereof is used.
Claims11
A process for hydrogenolysis of an alkali metal or alkaline earth metal salt of formic acid, which process comprises:
- in a reaction zone contacting a liquid phase solution of said salt of formic acid with hydrogen in contact with a catalyst having a catalytically active surface consisting essentially of metallic cobalt, rhenium, ruthenium, palladium, or platinum or mixtures thereof, said reaction zone being maintained at elevated temperatures and pressures sufficient to cause reaction of said salt of formic acid with said hydrogen to form methanol and a hydroxide of said alkali metal or alkaline earth metal, and withdrawing the reaction products from said reaction zone and separating said hydroxide therefrom.
A process for hydrogenolysis of an alkali metal or alkaline earth metal salt of formic acid, which process comprises:
- in a reaction zone contacting a liquid phase solution of said salt of formic acid with hydrogen in contact with a catalyst having a catalytically active surface consisting essentially of metallic cobalt, rhenium, ruthenium, palladium, or platinum or mixtures thereof, said reaction zone being maintained at a temperature within the range of 175.degree. to 275.degree.C and a pressure within the range of 125 to 400 atmospheres absolute, said temperatures and pressure being at least that sufficient to cause reaction of said salt with said hydrogen to form methanol and a hydroxide of said alkali metal or alkaline earth metal, and withdrawing the reaction products from said reaction zone and separating said hydroxide therefrom.
