| Resumo: |
Methodologies for reuse of organic solvent is a much discussed topic, given the growing search for sustainable processes. In this context, the present work aims to consolidate a methodology for the recovery of hexane mixed with ethyl acetate, which is frequently used in chemistry laboratories, by means of alkaline hydrolysis using sodium and potassium hydroxides. Refractometry and density analyzes were performed to plot a linear relationship between the properties and thus to evaluate the mixture samples. The closest values for recovery of Hexane to NaOH were at 0.9610 mol.L-1 and for KOH at 0.7297 mol.L-1. The results show that the methodology used addresses the expectations of the work. |
