Abstract
The invention provides a homogenous catalyst for the production of methanol from purified synthesis gas at low temperature and low pressure which includes a transition metal capable of forming transition metal complexes with coordinating ligands and an alkoxide, the catalyst dissolved in a methanol solvent system, provided the transition metal complex is not transition metal carbonyl. The coordinating ligands can be selected from the group consisting of N-donor ligands, P-donor ligands, O-donor ligands, C-donor ligands, halogens and mixtures thereof.

A homogeneous catalyst for the production of methanol from purified synthesis gas at low temperature and low pressure which comprises a transition metal capable of forming a transition metal complex with coordinating ligands, and an alkoxide, said catalyst dissolved in a methanol solvent system, provided said transition metal complex is not transition metal carbonyl.
A homogenous catalyst for the production of methanol from synthesis gas at low temperature and low pressure, said catalyst produced by reacting a transition metal complex having coordinating ligands selected from the group consisting of N-donor ligands, P-donor ligands, O-donor ligands, C-donor ligands, halogens and mixtures thereof or precursors thereof with an alkoxide in a methanol solvent system over a temperature range and pressure range over a period of time effective to form said catalyst, provided at least one C-donor ligand is not carbonyl.
A method of producing methanol from purified synthesis gas, said method comprising contacting said synthesis gas with a homogenous catalyst dissolved in a methanol solvent system at low temperature and low pressure, said catalyst including a transition metal complex with coordinating ligands provided said complex is not transition metal carbonyl.
A method for decomposition of a metal alkyl carbonate to carbon dioxide and the precursor metal alkoxide comprising contacting said metal alkyl carbonate with a homogenous metal carbonyl catalyst dissolved in a methanol solvent system, wherein the metal of said metal carbonyl catalyst is selected from metals of the groups consisting of Group 6, Group 7, Group 8, Group 9 and mixtures thereof.
