摘要： A process is described for continuous production of anhydrosugar alcohol by continuous introducing of sugar alcohols and/or monoanhydrosugar alcohols into a reaction vessel and dehydration in the presence of an acid catalyst and solvent in which the resultant reaction product is soluble. Water and the solvent having the dissolved reaction product are each cointinuously removed from the reaction vessel. The reaction product is separated from the removed solvent and the product is optionally purified to a purity of 99.0% the solvent is recycled in the reaction vessel.
