Abstract
An object of the invention is to provide a production method that can produce glycol from polyhydric alcohol with high selectivity and in a satisfactory yield. The object is achieved by using a silver catalyst in a reaction for synthesizing hydroxyketone from polyhydric alcohol having adjacent hydroxyl groups, and a hydrogenation catalyst in a reaction for synthesizing glycol from hydroxyketone.
