Curves for fusel oil and ethyl alcohol concentrations in both oil and water phases and percentage of fusel oil recovery as a function of water dilution ratios were presented for three mixtures. The results indicate that dilution ratios of 2 to 2.7 would improve fusel oil recovery by decantation.2) Some practical recommendations for fusel oil decanter connections and operations were made. %U https://www.ajevonline.org/content/ajev/9/2/64.full.pdf
