Interfacial Convection

The interfacial behaviour of two unstable binary liquid-liquid systems was investigated under normal gravitational conditions and under the microgravity conditions achieved in the NASA KC-135 parabolic flights to decouple gravitational instabilities from Marangoni instabilities. Results indicate that under normal gravitational conditions interfacial convection was observed in both systems. Under microgravity thermal Marangoni disturbances were strong enough to produce interfacial instabilities in one of the systems. Results are interpreted in terms of interactions between Marangoni and gravitational instabilities.

Miscibility Gaps

The miscibility gaps below 0 °C in the binary liquid systems of methylacetate with 14 alkanes having a number of carbon atoms nC between 5 and 9 have been measured. It has been shown how the coordinates of the critical solution points on the (Td, Nalkane) plane are parabolic functions of nC for the n-alkanes. Moreover, according to MALESINSKA, a generalized demixing curve has been drawn on the (Td/Tmax, z) plane.

Improved Accuracy

A calorimeter has been designed for measuring the heats of mixing of binary liquid systems, which eliminates the need to correct for changes in the composition of the vapour phase on mixing. Improved accuracy has thus been obtained. Heats of mixing have been measured for the three binary systems formed from the three components carbon tetrachloride, chloroform and methylene chloride, and also for the systems benzene + carbon tetrachloride and benzene + ethylene dichloride. Reports that the last system is ideal have been disproved.

Miscibility Gaps

The miscibility gaps (which can be represented through a unique generalized curve on the Td/Tmax vs. z plane) in the binary liquid systems of nitromethane with 13 (C5 —C9)-alkanes have been measured. Moreover, it has been shown that for the title systems and for those of MeOAc or MeOH with alkanes the temperatures Tmax obey a simple additive rule, at least as a first approximation.

Excess Parameters

Molecular interaction studies using ultrasonic technique in the binary liquid mixtures of cyclohexanone witho-cresol andp-cresol have been carried out at 303 K. Using the measured values of ultrasonic velocity, density and viscosity, acoustical parameters and their excess values are evaluated. From the properties of these excess parameters the nature and strength of the interactions in these binary systems are discussed.
