Document Type and Number:
Japanese Patent JP3208152
Kind Code:
B2
Abstract:
PURPOSE:To produce a novel sugar ester excellent in emulsifiability, foamability, water solubility. etc., and useful as an emulsifier, colloid-protecting agent, etc., by reacting a saccharide with an alkenyl succinic anhydride in the presence of an alkali catalyst. CONSTITUTION:A saccharide such as glucose is reacted with an alkenyl succinic anhydride such as octenyl succinic anhydride in the presence of an alkali catalyst such as NaOH to produce the objective alkenyl succinic anhydride. Concretely, the reaction is carried out by the steps of dissolving the saccharide in water, in a mixture of the water with an alcohol, etc.; adding the alkenyl succinic anhydride to the solution; further adding the alkali catalyst to the solution; and subsequently stirring the solution preferably at a pH of 6-8.
