Production of Butyl Acetate by Catalytic Distillation:  Process Design Studies

Abstract

A simulation-based design method is employed to figure out the promising reactive distillation process configuration for the production of butyl acetate. The intrinsic kinetics developed for the esterification and the unwanted side reaction etherification over the Amberlyst-15 catalyst 1 are utilized to evaluate the steady-state performance of different reactive distillation processes. A steady-state column model is developed and compared with experimental data from the literature. 2,3 With this model, three different column configurations are investigated for the production of butyl acetate with the goal of eliminating the formation of byproduct dibutyl ether and achieving a high purity of the desired product butyl acetate. The following column configurations are explored: (a) a column with a nonreactive rectifying section and a reactive stripping section; (b) a column with a nonreactive rectifying section, a nonreactive stripping section, and a reactive middle section; and (c) a conventional distillation column with a cocurrent pump-around reactor. Configuration c is compared with the side reactor configuration, where the pump-around reactor is coupled to the column in a countercurrent fashion.

Design and Control of the Butyl Acetate Process

“…But the opposite effect is displayed in the butanol/butyl acetate system, as shown in Figure 8. 3. In this study, the butanol column separating butanol and butyl acetate operates at 4 atm.…”

New processes for recovery of acetic acid from waste water

“…The above-validated phase split routine is combined with a heterogeneously catalyzed continuous reactive distillation column model from Gangadwala et al (2004) to design the acetic acid recovery process. In this section we present a few possible column configurations for the recovery process.…”

Formulation and physicochemical properties of promising avermectin microemulsion with biodegradable surfactant and oil

“…BuAc can dissolve many kinds of pesticides such as organophosphate, pyrethroid and carbamate, besides, application of BuAc in pesticide emulsifiable concentrate has been already published. [16,17] The main purpose of this study was to prepare a microemulsion formulation, with biodegradable surfactants (APG and LAS) and oil (BuAc), as a potential delivery system for oil-soluble pesticides. The model active ingredient used in this study is avermectin (CAS NO.…”
