ABSTRACT:
A method for lowering the reducing sugar content of glycoside compositions by adding 1 to 10 wt. % of an orthoformic ester or an acetal of a low-boiling ketone is described. Reducing sugar contents can be lowered from 1 to 3 wt. % to 0.05 to 0.3 wt. % using compounds such as trimethyl orthoformate, triethyl orthoformate and 2,2-dimethoxypropane. Glycoside compositions particularly useful in this method are those formed by the catalytic reaction of starch hydrolysates with low molecular weight polyols. Such glycoside compositions are useful to make high molecular weight polyols having low color suitable for incorporation into polyurethane foams.
