Glycoside preparation directly from aqueous saccharide solutions or syrups

摘要

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.
