  • N. S. Dhar


Excess molar volumes of benzene or methylbenzene + 2-methylethylbenzene at 25, 35 and 45°C and of ethylbenzene + 2-methylethylbenzene at 25°C have been determined from density measurements using a vibrating tube densimeter. Experimental V m E values have been compared with calculated values based on the Flory theory.

Key Words

Excess molar volume alkylbenzenes orientational order Flory
