실험 절차

A 100 ml round bottom flask equipped with a condenser, addition funnel, thermometer and mechanical stirrer was charged with D-glucono-1,5-lactone (5.4 g, 0.03 mole) and methanol (7 g). The suspension was heated to 40° C. over 15 minutes and the heating mantle removed. Soya-aminopropylamine (10.0 g, 0.03 mole) was added dropwise over 15 minutes with rapid stirring. The reaction mixture was cooled and placed in a refrigerator at 0° C. overnight. The white product was filtered, washed with cold isopropanol (3×100 ml) and dried under vacuum at 35° C. giving 14.1 g (92% yield) of soyaaminopropyl D-gluconamide with a melting point of 97°-100° C.
