A re-examination of the nitrobenzene – 2,2,4-trimethyl pentane system in the consolute region and of the thermodynamical considerations concerning the value of ε′ at the consolute point

Abstract

Failure to find maxima in ε′and ε″for aniline–cyclohexane in the consolute region by Lubezky and McIntosh (8) led to re-examination of the system nitrobenzene–2,2,4-trimethyl pentane for which anomalous values of ε′and ε″ have been reported. Earlier results by Lubezky and McIntosh (6) could not be repeated. A re-examination of thermodynamical arguments was then undertaken and the conclusion reached that these do not predict anomalous values of ε′.
