each adsorbed on one centre. The surface reaction is the rate-
limiting step. The kinetic data for the esterification of acetic
acid with isoamyl alcohol would be useful for the simula-
tion and design of a reactive distillation column for removing
acetic acid from aqueous streams. We are currently engaged
in further studies on esterification of acetic acid with isoamyl
alcohol in an RDC bearing in mind the recovery of acetic
acid from aqueous streams.
