标 题 :Process for low pressure synthesis of ethylene glycol from synthesis gas
发明人：KNIFTON JOHN F; DURANLEAU ROGER G
权利人:TEXACO INC
摘要:This invention relates to the manufacture of ethylene glcyol and more particularly to a low pressure process for making ethylene glycol comprising reacting synthesis gas, i.e. a mixture of carbon monoxide and hydrogen, plus formaldehyde in the presence of a homogeneous liquid catalyst containing an effective amount of cobalt-containing compound and a silicon or germanium-containing promoter and a solvent at a temperature of at least 50 DEG C. and a pressure of at least 500 psi wherein said ethylene glycol product separates as a separate liquid phase from the solvent.

标题:Production of ethanol from methanol and synthesis gas
发明人：LIN JIANG-JEN; KNIFTON JOHN F
权利人:TEXACO INC
摘要:Ethanol is formed by contacting a mixture of carbon monoxide, hydrogen and methanol with a catalyst comprising a cobalt-containing compound and a germanium-containing compound, such as dicobalt octacarbonyl and triphenylgermanium hydride in the presence of an inert, oxygenated hydrocarbon solvent at a temperature of about 50 DEG to about 350 DEG C. and at a pressure of about 500 psig or greater.
