Abstract
The present invention relates to a method for preparing mannitol which includes performing the hydrogenation of fructose in the presence of a Cu-based nanocomposite catalyst, for example, a nanocomposite catalyst of CuO(x)/SiO2(100-x) (wherein x is a real number from 20 to 90), using butanol as a solvent.
