ABSTRACT:
An integrated continuous process is disclosed for the manufacture of high purity, polymer grade dianhydro sugar alcohols, such as isosorbide, by the dehydration of corresponding sugar alcohols. The water vapors evolved during the dehydration are used to separate product dianhydro sugar alcohols from the high boiling byproducts in the reaction mass. The product is recovered from the vapor stream as high purity crystals. The high boiling reaction byproducts are recycled.
