Binary Mixture Research Paper

2007
Ram Tawakya Singh and Praveen Kumar Thakur have studied three types of binary mixture compared with its theoretical values which is based on nomto’s relation, van deal and vangeel additive mixture relations. o-cresol + acetophenone, o-cresol + ethyl acetate and o-cresol + methyl ethyl ketone mixtures reported the maximum value of molecular interaction around 0.53, 0.69 and 0.47 mole fractions of o-cresol. In o-cresol-acetophenone percentage deviations of velocity and interaction deviations of Rao's constant, Wada's constant and molar volume are both positive and negative. In o-cresol-ethyl acetate percentage deviations of velocity and interaction term α are found to positive only, where as the percentage deviations of Rao's constant, Wada's constant and molar volume are found to be negative. In o-cresol-methyl ethyl ketone percentage deviations of velocity and molecular interaction term are found to be positive, that of molar volume negative and that of Rao's constant and Wada's constant both positive and negative [1]

Mainar, Juan I. Pardo, and Jose S. Urieta have determined and calculated the binary mixtures ß-pinene + 2-methyl-1- propanol at the temperatures (283.15, 298.15, 303.15, 313.15, and 323.15) K and ß-pinene + 2-methyl-2-propanol at the temperatures (303.15, 313.15, and 323.15) K. The excess molar enthalpies and excess molar volumes are positive on the whole composition range for the mixtures of the hydrocarbon ß-pinene with both alkanols at all temperatures. excess molar volumes for ß-pinene + 1-butanol and ß-pinene + 2-methyl-1-propanol are very similar, being slightly greater when the alkanol is branched. Mixture with 2-methyl-2-propanol, quite unusual behavior is observed in both speed of sound deviation and excess isentropic compressibility. This happened due to the 2-methyl- 2-propanol is less associated than
