Abstract

Liquid-Liquid-and Vapor-Liquid-Equilibria in binary and ternary systems consisting of n-heptane, ethylbenzene and sulfolane were investigated experimentally at 312.57 and 332.45 K in three different types of apparatus using analytical or synthetic methods, static or dynamic operation and measuring temperatures or differential temperatures, pressures or differential pressures. Densities in binary mixtures consisting of n-heptane-ethyl-benzene, sulfolane—ethylbenzene were measured with an oscillating U-tube densimeter as a function of concentration at 293.25 and 303.6 K.
