The hydrolysis of some tailor‐made Schiff bases having flexible spacers between aldimine groups and alkoxy groups at ortho ( o ) or para ( p ) position in the benzene ring has been investigated in microemulsion media. The kinetic data of acid‐catalyzed hydrolysis in anionic (sodium lauryl sulphate: NaLS) and cationic (cetyltrimethyl ammoniumbromide: CTAB) microemulsion media have been explained considering the localization of the Schiff bases at various probable pockets of the microemulsion droplet. The results are in conformity to the solubilization studies of the reported Schiff bases in microemulsions (Dash et al., Spectrochim Acta 1996, 52A, 349). The change in reactivity due to change in the spacer length and position of the alkoxy group in the Schiff bases has been rationalized on the basis of localization sites of the reaction center at different polarity pockets of the reaction media. © 2001 John Wiley & Sons, Inc.
