摘要：

A process for preparing materials derived from sugar alcohols such that the dehydration products exhibit better accountability and improved color to water-clear or near water-white appearance is described. In particular, the process involves employing a reducing Brnsted acid (e.g., phosphonic acid) for the catalysis of sugar alcohols to their corresponding dehydrated-cyclized products.
