Abstract: The kinetic study showed that the water content has an important effect on the hydrolysis rate of phthalimidyl benzene sulphonyl chloride(Phisyl-Cl). The PH of the reaction medium should be higher than 8.0 and 9.0 for derivatization with primary and secondary amines respectively. The hydrolysis of Phisyl-Cl is inhibited by adding solid NaHCO3 instead of its saturated solution to the medium to promote derivatization.

Key words: phthalimidylbenzene sulphonyl chloride, amine, derivatizing reagent, derivatization
