摘要：

The kinetics of the hydrolysis of picryl chloride were studied between pH 7.06 and 11.60 with different buffers at various concentrations. The reaction is strongly catalyzed by tertiary amines (IV-ethylmorpholine, 2, 4, 6-tri-methylpyridine, and Dabco) and also by carbonate and bicarbonate. A small increase in rate is also observed with phosphate trianion and borate. The catalysis seems to be of the nucleophilic type for N-ethylmorpholine, 2, 4, 6-trimethylpyridine, carbonate, and bicarbonate, but a mechanism involving general base-catalyzed addition of water is suggested for the other bases. © 1979, American Chemical Society.
