Abstract
A method of making of 1,2,5,6-hexanetetrol (“tetrol”). The method includes the steps of contacting a reaction solution containing water as well as levoglucosenone, dihydrolevoglucosenone, and/or levoglucosanol, with a catalyst containing metal and acid functionalities, at temperature of from about 100° C. to about 175° C., and a hydrogen partial pressure of from about 1 bar to about 50 bar (about 0.1 MPa to about 5 MPa), and for a time wherein at least a portion of the reactant is converted into 1,2,5,6-hexanetetrol.

A method of making of 1,2,5,6-hexanetetrol, the method comprising:
- contacting a solution comprising levoglucosenone, dihydrolevoglucosenone, or levoglucosanol, or mixtures thereof and water, with a catalyst containing metal sites and acid sites, at temperature of from about 100° C. to about 175° C., and a hydrogen partial pressure of from about 1 bar to about 50 bar (about 0.1 MPa to about 5 MPa), and for a time wherein at least a portion of the levoglucosenone, dihydrolevoglucosenone, or levoglucosanol, or mixtures thereof is converted into 1,2,5,6-hexanetetrol.
