SOLID-LIQUID EQUILIBRIA IN BINARY-MIXTURES OF ORGANIC-COMPOUNDS

Solid-liquid phase equilibria for the systems indane/nitrobenzene, ind ane/dodecane, acenaphthene/1,4-xylene, tetrachloromethane/2-dodecanone , tetrachloromethane/2-undecanone, 1,2-xylene/1,3-xylene, 1,4-xylene/1 ,3-xylene, and 1,2-xylene/1,4-xylene were measured visually using the synthetic method. The measured systems were calculated by means of the group contribution method UNIFAC and modified UNIFAC (Dortmund). If n ecessary, solid-solid transitions were taken into account in the calcu lations. The systems selected are of technical interest and can also b e used for checking and the further development of the group contribut ion method modified UNIFAC (Dortmund).
