Abstract
Glycoside products are successfully prepared directly from aqueous saccharide solutions or syrups, and with acceptably low levels of undesired homopolymerized saccharide by-products, by dissolving same in the desired alcohol reactant or in an alcohol reactant plus glycoside product mixture and contacting the resulting homogeneous aqueous saccharide solution and alcohol-containing reaction medium with an acid catalyst in a fashion such that no separate or distinct, substantially alcohol reactant-free aqueous saccharide solution-containing phase is permitted to come into contact with said acid catalyst material under conditions conductive to homopolymerization of said saccharide reactant.
