Abstract
There is provided is a method for making a higher purity alcohol comprising: a) contacting an impure alcohol composition comprising: (i) an alcohol compound; and (ii) from about 50 ppm to about 5 weight percent, based on the weight of the impure alcohol composition, of at least one hydrogenable contaminant having an unsaturated bond, with hydrogen in a hydrogenation reactor and in the presence of a hydrogenation catalyst to produce a reaction mixture comprising the alcohol compound and a hydrogenated contaminant product wherein at least 10 mole % of the at least one hydrogenable contaminant in the reaction mixture is converted; and b) separating the alcohol compound from at least a portion of the reaction mixture to produce an enriched alcohol composition having a lower concentration of the hydrogenated contaminant product. There is also provided an alcohol composition having less than about 500 ppm of at least one hydrogenable contaminant.
