processo para a produção de um dianidroaçúcar

An enhanced process for the production of a dianhydrosugar, such as isosorbide, from the corresponding sugar alcohol is described. The sugar alcohol is combined with an acid catalyst and reacted at elevated temperatures and at atmospheric pressure, eliminating the need for a vacuum. High selectivity...

Zusammenfassung:An enhanced process for the production of a dianhydrosugar, such as isosorbide, from the corresponding sugar alcohol is described. The sugar alcohol is combined with an acid catalyst and reacted at elevated temperatures and at atmospheric pressure, eliminating the need for a vacuum. High selectivity and yields are achieved.
