Synthesis of n-butyl acetate system using a reactive distillation from a agro-industrial waste.

Abstract

This work understands a study in the potential use of the oil of Fusel, an agro-industrial waste, of which the alcohol obtains n-butílico for the production acetate of n-butilo in a system ecoeficiente combined reaction-separation to pilot scale, using a catalyst such as ion exchange resin (Purolite C-100). The experiments were performed at constant pressure (P = 0,936 atm) and different conditions of input. The final composition of the ester reached by the system operating at different conditions of input demonstrated the many advantages of this process over the conventional technique for the synthesis of organic compounds with higher purity. The simulation of the column is made in Aspen Plus based on the experimental information provided, with the purpose of reproducing the data. The most important findings a 46% alcohol and that the best condition of operation in reactive distillation column found consisted of an excess of acetic acid (2:1 molar ratio) reaching a final composition of butyl acetate equal to 99 % and considerably lower energy.
