Production Of Oxygen-Containing Compound
PURPOSE: To improve the yield of the subject compound by allowing steam within a restricted concentration range to co-exist in raw material gases when carbon monoxide is reacted with hydrogen in the presence of a catalyst.
CONSTITUTION: For example, raw material gases containing carbon monoxide, hydrogen and 0.02-0.5 vol.% of steam and introduced into a fixed bed reactor filled with a catalyst containing rhodium and reacted with each other to provide the objective compound. Or, if circumstances require, the catalyst is suspended in a suitable solvent and introduced into the raw material gases to cause a liquid phase reaction to provide the objective compound. The reaction is carried out under a pressure of 0-300 kg/cm2 gauge, particularly 20-200 kg/cm2 gauge, within a temperature range of 150-450oC, preferably 200-350oC. The space rate of the raw material gases per catalyst volume is preferably a range of 103-5 x 104/hr converted into a measurement at 0oC and under 1 atmospheric pressure. The molar ratio of the carbon monoxide and hydrogen is 30:1-1:5, preferably 25:1-1:2
