Excess molar volumes of 2-methylethylbenzene with benzene,methylbenzene or ethylbenzene at various temperatures

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.List of Symbols p_i characteristic pressure of pure component - reduced temperature of pure component - V^E excess molar volume - V_i^* characteristic volume of pure component - reduced volume of mixture - reduced volume of pure component i - X₁₂ interaction parameter in Flory's theory - site fraction of component 2 - segment fraction of component 2
