| titleOfInvention | Production of 5-membered and 6-membered cyclic esters of polyols |
| abstract | Described herein are improved methods for the preparation of 5- and 6-membered cyclic mono and diesters of sugar alcohols and anhydrosugar alcohols by reaction with an organic acid RCOOH over a solid acidic substrate. The process is adaptable to a continuous process for simultaneously making and separating the cyclic esters from the sugar alcohols and anhydrosugar alcohols under mild conditions using the solid acid substrate as both the catalyst and a chromatographic bed for separation. The reactions are performed at mild temperatures of 70 DEG C to 100 DEG C and the formation of the cyclic esters is nearly quantitative. Also described is a method for making 5- and 6-membered cyclic mono and diesters of sugar alcohols and anhydrosugar alcohols using microwave irradiation in the presence of the organic acid. |
