“…It was established that the best extraction properties are shown by an aqueous solution of NMP, by propylene carbonate, and by mixed methyl and ethyl carbamates whereas furfural, morpholine, and DEG have relatively poor extraction properties in dearomatizing the kerosene cut. However, the use of such comparatively highly selective and high-boiling extractives such as sulfolane, DEG, TEG and propylene carbonate proposed for dearomatization of kerosene 82,83 and diesel 84 fractions is complicated by the impossibility of regenerating them by fractionation, which is due to the formation of azeotropic mixtures with components of the feedstock.…”
