Description :
The kinetics of iodiation of salicylic acid inhibited by micelle h
as been investigated in aqueous
iodine and in the presence of cationic surfactant cetyltrimethyl ammonium bromide (CTAB) at 50

C. The
reaction followed first order kinetics with respect to salicylic acid and iodine. Increase in CTAB
concentration decreases
the specific reaction rate values. The specific reaction rate of iodination of
salicylic acid, in absence of CTAB is found to be 2.57×10

C. The iodinating species in micelle
media have been discussed in detail. The possible schematic
representation of interaction of reactants in
micelle have been shown.
