Ten organic sulfur compounds, ethanethiol, 2-methyl-2-propanethiol, 1-pentanethiol, 2-thiabutane, 3-thiapentane, thiacyclobutane, thiacyclopentane, 2,3-dithiabutane, 3,4-dithiahexane and thiophene, were purified to at least 99.9 mole percent purity. The stability of the compounds under storage and distillation conditions was investigated. In addition to the boiling point and freezing point, the following properties were measured at 20, 25 and 30/sup 0/: density, viscosity, surface tension and refractive index for the r, C, D, e, v, F and g lines. Derived functions including refractivity intercept, specific dispersion, molecular refraction, parachor and molar volume were calculated and are discussed briefly. Mass, infrared and ultraviolet spectra were determined permitting some correlation of the effect of sulfur groupings on spectra.
