Versuchsvorschrift

Sodium hydroxide 8 g was added to a suspension of 13.3 g L-aspartic acid in 72 ml water and 48 ml acetone to form a solution of disodium L-aspartate. This solution was held at 0°C, and the solution of palmitic acid-sulfuric acid mixed acid anhydride and a solution of 12 g sodium hydroxide in 30 ml water was added dropwise simultaneously with stirring. This solution was stirred for 1 hour at 0°C.
