摘要：

A process is provided for making isohexides such as isosorbide with reduced color and/or improved color stability on storage, wherein ionic species in the crude dehydration product mixture are chromatographically substantially separated from the remainder of the crude product mixture, then the remainder is refined to yield a finished product for further use or sale.
