Vapor‐liquid equilibria and heat of mixing: n‐octane–ethylbenzene–cellosolve system

Vapor‐liquid equilibria of the systems n –octane–Cellosolve, ethylbenzene‐Cellosolve, and n –octane–ethylbenzene‐Cellosolve were determined at 760 mm. Hg. The activity coefficient data of Yang and Van Winkle ( 23 ) for the system n –octane–ethylbenzene and the data of this work on other systems were expressed by Wohl's three‐suffix Margules equations. The ternary data are predicted satisfactorily from the binary constants and no noticeable ternary effects seem to exist for this ternary system.
