Abstract

Experimental observations on the use of a batch pulsed baffled reactor are reported in this paper. The irreversible reaction between sodium hydroxide and ethyl acetate, NaOH+CH₃COOC₂H₅→CH₃COONa+C₂H₅OH, is followed as a model example in both a pulsed baffled and a stirred tank reactor. Reaction species were pre-mixed with carboxymethylcellulose (CMC) sodium salt in order to increase the viscosity of the solution and make the fluid mixing within the vessel a critical parameter. The results show that reaction kinetics are similar for both devices and air entrainment problems are limited to the stirred tank reactor. Power density considerations show that the pulsed baffled reactor is more energy efficient than the stirred tank reactor.
