    摘要: The present invention relates to a preparation method for alcohol by reacting carboxylic acid, alcohol, and hydrogen using hydrogenation catalysts. More specifically, the invention relates to a method for preparing alcohol by performing esterification and hydrocracking in a one-step process using hydrogenation catalysts instead of a two-step process. According to the invention, alcohol is prepared from carboxylic acid through esterification and hydrogenation in a one-step process using hydrogenation catalysts. Therefore, production costs and by-product treatment costs can be reduced in comparison to a two-step process. In addition, the invention is effective and economical since it can produce alcohol at relatively high yield by a simple process. Further, the invention allows high yield at relatively lower pressure when compared to alcohol production from carboxylic acid through hydrogenation without esterification and solves the problems of leaching by catalysts.
