Samples of benzene-d6 and cyclohexane-d12 of up to 99.3 and 98.8% deuteration, respectively, have been prepared by stepwise equilibration of benzene with sulfuric acid-d2, followed by reduction with deuterium over nickel catalyst for conversion to the cyclohexane-d12. Density and refractive index of these materials at 20, 40 and 60° have been measured, and molar volumes and refractions calculated. The physical properties are compared with those of the protium isomers. A relation between the density-temperature coefficients and the molecular weights of the isotope pairs is noted, and some possible implications suggested. 1954, American Chemical Society.
