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 under pressure. Optionally the resulting product is purified. Very high purities are achieved, without necessitating the use of organic solvents in the process.
