Abstract: A process for preparing alkyl polysaccharides comprising introducing a mixture of a hydrous saccharide in a first portion of fatty alcohol, introducing a second portion of fatty alcohol, agitating the mixture, allowing it to crystallize, reducing water content, contacting the reduced water content dispersion containing solid particles with an effective amount of acid catalyst and reacting the aliphatic alcohol with the saccharide source to form an alkylpolyglycoside.

Abstract: Glycoside-containing polyester products having improved color characteristics are provided by a polyester preparation process in which a polyol reactant containing at least a minor proportion of a glycoside reactant is reacted with a lower alkyl ester of a polybasic acid. The color characteristics of such products are notably improved relative to that which is obtained when said reaction is instead conducted using the corresponding polybasic acid or anhydride in place of the indicated lower alkyl ester thereof.The color improvement benefits of the present invention are particularly pronounced and dramatic when the polybasic acid component of the desired polyester product comprises an aromatic polybasic acid and when a lower alkyl ester of said aromatic polybasic acid is employed in the reaction in place of the aromatic acid itself.
