The miscibility of nitrobenzene with n-hexane and their deuterated forms over a broad concentration range has been determined. All themeasured systems present the phase diagrams with the upper critical solution temperature (UCST). It appears that deuterium substitution in CH bonds in either molecule leads to the remarkable upward shift of the UCST, increasing the domain of the limited miscibility. The phase diagrams were described by a scaling equation with a critical exponent beta close to the theoretically predicted value and practically independent of isotope substitution. The origin of the isotope effects on the miscibility in the systems studied was briefly discussed.
