Abstract: The present invention relates to a method for dehydrating polyols such as sorbitol, mannitol, xylitol, and arabinitol and, more specifically, to a method for dehydrating polyols capable of achieving a high dehydration conversion rate, high selectivity, and high yields by using a sulfated solid catalyst. The method for dehydrating the polyol according to the present invention is a very economical method since the sulfated solid catalyst is reusable by recovering after used in the dehydration reaction of the polyols.
