Abstract

Water-ethyl acetate-ethanol is widely used as “green” extractant system. We show that two different types of phase separation can be induced upon centrifugation in this ternary system using ethanol as a co-solvent of water and ethyl acetate (EA): centrifuge-induced criticality and centrifuge-induced emulsification. The expected composition profiles of samples after ...
