The vapor-liquid equilibrium data are necessary for the design of the distillation columns which separate the mixture mesitylene – ABE components resulting from the liquid-liquid extraction of butanol from the ABE using 1,3,5-trimethylbenzene as so

Vapor–liquid equilibrium data was determined by using a static method for the binary mixtures of dipropylene glycol (4-oxa-2,6-heptanediol) with benzene, toluene, ethylbenzene, o-xylene, m-xylene, and p-xylene at temperatures within 293.15 K–481.
