Abstract
He이 CF4 및 CClF3에 무한희석된 상태하에서의 Henry's law constant와 partial molar volume을 Krichevsky Kasarnovsky식을 이용하여 상평형실험 data로부터 얻고 또한 이론적으로 계산하여 얻었다. 본 연구에서 취급한 계에서의 Henry's law constant는 지금까지 연구된 어떤 helium 이성분계에서 보다도 제일 큰 사실이 발견되었다. 무한희석된 상태하에서의Henry's law constant와 partial molar volume을 추정하기 위해 Snider와 Herrington이 제시한 유체에 대한 hard sphere model을 이용했다. 추정된 치와 실험치와는 시리험치의 55 %이내의 오차를 가지고 있었다.
The Henry's law constants and partial molar volumes at infinite dilution for helium in CF4 and CClF3 have been extracted from the experimental phase equilibrium data1) using the Krichevsky-Kasarnovsky equation3) and also theoretically predicted. It has been found that the Henry's law constants for the systems considered in this work are larger than those for any other helium binary systems investigated so far at a given reduced temperature. The hard sphere model of fluids as presented by Snider and Herrington2) has been used to predict the Henry's law constants and the partial molar volumes at infinite dilution. The predicted values agreed with the experimental values within at most 55 % of the experimental values.
