Abstract:
A method for producing anhydrosugar alcohol according to the present invention can increase the yield of anhydrosugar alcohol even in the absence of a catalyst or in the presence of a small amount of a transition metal salt catalyst by controlling the temperature of a high-temperature reaction, which converts sugar alcohol to anhydrosugar alcohol, in two steps, that is, a first low-temperature reaction step and a second high-temperature reaction step.
