Abstract: A continuous process for making alkyl aldosides from polysaccharides and more particularly mixed alkyl glycosides from starch by direct alcoholysis. A polysaccharide, such as starch, is slurried in an alcohol and passed through a heated, confined zone under pressure in the presence of an acid catalyst to form a mixed alkyl aldoside. The alcohols which may be used include methanol, ethanol, propanol and butanol, their isomers and mixtures thereof. Higher alkyl glycosides are surfactants and, in some instances, it is advantageous to use higher alcohols, such as decyl and dodecyl alcohols, to obtain particular surfactant properties in the resulting alkyl glycosides. Mixed alkyl glycosides are useful in detergent applications, and as backbone polymers in polyurethane foams.

Abstract: An improved method for the production of polyether polyol compositions is disclosed wherein a polyhydric initiator is oxyalkylated with alkylene epoxides at lower temperatures in the presence of an aqueous ammonia solution. The polyether polyol compositions produced have desirable hydroxyl numbers and low viscosities and are particularly useful in the production of excellent rigid polyurethane foams. In addition to catalyzing the reaction, the nitrogen containing moiety itself undergoes oxyalkylation during the process such that the polyether polyol compositions produced contain, admixed therewith, various alkoxyalkanol amines. The alkoxyalkanol amines having reactive hydroxyl groups and acting as a mild catalyst for the polyolisocyanate reaction need not be removed from the polyether polyol composition. In addition, the alkoxyalkanol amines increase the blending compatibility of the polyether polyol compositions.
