SHARP DISTILLATION FOR QUATERNARY SYSTEMS

open access: yesТонкие химические технологии, 2018
Conditions of sharp distillation were considered for zeotropic quaternary system (two pairs of components are characterized by relative volatility close to 1) and systems with one (with minimum or maximum boiling point) and two (with minimum and maximum ...
