ABSTRACT:
A process is provided for the preparation of anhydrosugar alcohols. The process involves heating a sugar alcohol or a monoanhydrosugar alcohol starting material in the presence of an acid catalyst, and subsequent purification of the anhydrosugar alcohol. Very high purities are achieved, without the use of organic solvents in the process.
