Abstract
A survey of the literature gave no reference to the n-Propanol Glycol system while the n-Propanol-Benzene system had been previously studied. Experimental data were found to agree closely with those existing in literature for the n-Propanol-Benzene binary system.
A ternary miscibility diagram at fixed temperature was found to give first-type of miscibility curve, i.e. n-Propanol was completely miscible in all proportions with Benzene and Ethylene Glycol, while Benzene and Ethylene Glycol were found to be partially miscible. The plait-point was determined by drawing tie-lines and using the Sherwood method as well as by the loga rithmic method of Hand. Both correlate well.
Binary miscibility at various temperatures was determined between Benzene and Ethylene Glycol.
An experimental determination of the vapor-liquid equilibria was done by using a modified Othmer still and a standard Cottrell type still. Two binary systems, n-Propanol (C3H8O)-Ethylene Glycol (C2H6O) and n-Propanol-Benzene (C6H6) were studied under isobaric conditions.
The modified Othmer still was found to give excellent data for n-Propanol-Benzene binary systems but difficulty was encountered during the equilibrium of n-Propanol-Ethylene Glycol binary system. It was observed that too great a hold-up of the condensate caused difficulty; hence a modification is being proposed which is quite similar to Cottrell's stop-cock construction.
The Margules binary equations were found best to correlate the present experimental data.
