Influence of ph on the decomposition of N-chlorodiethanolamine

Abstract The kinetics of the decomposition of N-chlorodiethanolamine in water were studied over the range PH 6.55-12.01. Its coefficient of absorption in water at various pH and its protonation constant are reported, and the mechanism of its formation and decomposition is discussed. Comparison of the stabilities of various N-chloramines shows that the OH group of N-chloroalcoholamines makes them less stable than other N-chloramines and that the mechanism by which they react differs from that of aliphatic N-chloramines.

STUDIES ON THE STABILITY OF N-CHLORO-AMINOACIDS. DECOMPOSITION OF N-CHLORO-L-SERINE

Abstract Over the range pH 6–9 the rate of decomposition of N‐chloro‐L‐serine is independent of ionic strength, pH, and its own concentration. The average rate constant at 25°C is 0.0178 min−1 (a mean half life of 39 minutes).
