摘要：
This invention relates to a process for the catalytic hydrogenation of alpha-hydroxy ketones to the corresponding alcohol in a heterogeneous liquid phase reaction medium which contains a carboxylic acid. The carboxylic acid may be a simple carboxylic acid or a hydroxy carboxylic acid.
The presence of the carboxylic acid improves both the yield of and selectivity to the alcohol product.
The presence of the carboxylic acid improves both the yield of and selectivity to the alcohol product.
