The invention relates to a process for producing an alcohol including hydrogenating an aldehyde using a hydrogenation catalyst and subjecting the resultant product to distillation/purification, wherein the resultant hydrogenation product is subjected to distillation/purification in the absence of the hydrogenation catalyst or in the presence of the hydrogenation catalyst in such an amount that does not cause a dehydrogenation reaction.

Process for producing alcohol

A process for producing a purified alcohol giving satisfactory results in a sulfuric acid coloring test is provided. A process for producing a purified alcohol which includes the following steps:

Process for production of purified alcohols

It is an object of the present invention to obtain a highly pure alcohol by reducing the aldehyde concentration in the product alcohol efficiently and inexpensively. The invention relates to a process for producing an alcohol including hydrogenating an aldehyde and subjecting the resultant product to distillation/purification, wherein a total amount of oxygen introduced into the distillation/purification step is 0.0034 mol/s or less of oxygen per 1 kg/s of the product alcohol.
