Reaction Conditions

Reaction Steps

99 g (1.40 mol) of chlorine are introduced with stirring at about 0 to 5° C. into a solution of 100 g of acrylic acid amide in 1000 ml of chloroform. After stirring for 3 hours at about 20° C., 270 g (2.13 mol) of oxalyl chloride are added dropwise with continued stirring. The solution is then boiled under reflux until the evolution of gas is complete. Fractional distillation of the reaction solution gives 172 g (72 % of the theoretical amount) of 2,3-dichloropropionyl isocyanate boiling at 38 to 41° C./1.0 Torr.
