โœฆ Synopsis

A rapid method is presented for the determination of vapor pressure/molecular weight correlations for homologous hydrocarbon mixtures. By comparing droplet evaporation data to discretizad theoretical continuum mass flux rates which employ two parameter expouential vapor prassure/molecular weight correlations, best fit pressure correlation parameters are determined. The present technique is applied to the multicomponent oil mixture, 100 pale oil, which is modeled as a fifteen component system. Postulating the mixture is tbermodynamlcally ideal, best fit pressure correlations are determined which result in less than 5% error between theory and experiment. It is shown the hydrocarbon vapor pressure calculated from the derived pressure corralation is in satisfactory agreement with pressures calculated from distillation data and the Clausius Clapayron relation.

Mercury vapor pressure over clinically used amalgams, as well as the individual phases composing dental amalgam, has been determined from weight loss data using Langmuir's time averaged weight loss technique. The results show that the Hg vapor pressure of 38.2 X 10-6 torr over the pure y1 (AgPHgl) p

In this work, we determined the number average molecular weight of some polyethylene glycols (PEGs) using vapor pressure osmometry. In general, this technique works with a plot of Dr p /c p versus c p (concentration) and the molecular weight is determined by the calibration constant obtained from th
