An apparatus for the accurate determination of liquid-vapour equilibria is described. Data obtained with it for the system carbon tetrachloride-cyclohexane at 70 �C. and the thermodynamic functions derived from these are shown to agree with the corresponding values determined by Scatchard, Wood, and Mochel(1). Equilibrium data of the system water-acetic acid have been measured at 760 mm. Hg, particular attention being given to high acetic acid concentrations. These results are compared with published values and the excess chemical potentials of the components have been calculated.

The optical rotation of various concentrations of L-valine and L-leucine, dissolved in glacial acetic acid, or 5 or 6 M HCl, was measured with a photoelectric polarimeter at the nominal wavelengths 589, 578, 546, 436, and 365 nm and temperatures of 20, 25, and 30 °C. The specific rotation for any one wavelength, solute, and solvent could be defined by the equation [α]λT = A(1 + D(T − 25)) + BC, where T is temperature in °C, C is concentration in grams of solute per 100 ml of solution, and A, B, and D are constants. The best fit values of the constants were determined by computer calculation and are listed. Constants are also given for calculating a specific rotation based on grams of solute per 100 g of solution.
