The effects of micelles of sodium dodecyl sulphate (SDS) on the rates of reactions of ionized phenyl salicylate (PS Γ ) with n-butylamine, piperidine and pyrrolidine were studied at 35 Β°C. Pseudo-first-order rate constants (k obs ) show a linear increase with increase in the total concentration of a

Pseudo first-order rate constants (kohl) for methanolysis of ionized phenyl salicylate (PS-) show a decrease of 3-5-fold with increase in CH,CN content from 2 to 60 or 70% (v/v) in mixed aqueous solvents containing 0.01 mol dm-3 LiOH and a constant content of CH30H. At 0.01 moldm-' KOH, the rate con
Nucleophilic second-order rate constants, k n ms , for the reactions of several primary and secondary amines with ionized phenyl salicylate (PS Οͺ ) show a nonlinear decrease with the increase in the content of CH 3 CN from 2 to Υ 50% v/v in mixed aqueous solvent. The values of k n ms remain almost un
The effects of mixed CH 3 CN 9 H 2 O solvents on rates of aminolysis of ionized phenyl salicylate, PS Οͺ , reveal a nonlinear decrease in the nucleophilic second-order rate constants, (for aminolysis) with increase in the content of CH 3 CN until it becomes Ο· 50%, ms k , n v/v.
