There is disclosed synthesis of CH.sub.3 OH from carbon monoxide and hydrogen using an extremely active homogeneous catalyst for methanol synthesis directly from synthesis gas. The catalyst operates preferably between 100.degree.-150.degree. C. and preferably at 100-150 psia synthesis gas to produce methanol. Use can be made of syngas mixtures which contain considerable quantities of other gases, such as nitrogen, methane or excess hydrogen. The catalyst is composed of two components: (a) a transition metal carbonyl complex and (b) an alkoxide component. In the simplest formulation, component (a) is a complex of nickel tetracarbonyl and component (b) is methoxide (CH.sub.3 O.sup.-), both being dissolved in a methanol solvent system. The presence of a co-solvent such as p-dioxane, THF, polyalcohols, ethers, hydrocarbons, and crown ethers accelerates the methanol synthesis reaction.
A method of producing methanol in a liquid those from synthesis gas comprising hydrogen and carbon monoxide which comprises contacting said synthesis gas with a homogeneous catalyst dissolved in methanol or methanol and a co-solvent, wherein said catalyst consists of a transition metal carbonyl complex, wherein the transition metal is selected from the group consisting of Cu, Ni, Pd, Co, Ru, Mo, Fe, and mixtures thereof, and an alkoxide.
