“…However, increasing deviations are observed with increasing temperatures above 270 K, with some exceeding 10 % at the highest temperatures (approaching the critical point). This discrepancy is also reflected in their measured critical temperature, a value that is lower by more than 3 K than that of Robinson and Senturk (1979a). The older data of Pearson et al (1932) also demonstrate a large deviation in the saturated liquid density from the data of Partington and Neville, as shown in Figure 6.…”

In a preceding project, functional forms for "short" Helmholtz energy equations of state for typical nonpolar and weakly polar fluids and for typical polar fluids were developed using simultaneous optimization. In this work, the coefficients of these short forms for the equations of state have been fitted for the fluids acetone, carbon monoxide, carbonyl sulfide, decane, hydrogen sulfide, 2-methylbutane (isopentane), 2,2-dimethylpropane (neopentane), 2-methylpentane (isohexane), krypton, nitrous oxide, nonane, sulfur dioxide, toluene, xenon, hexafluoroethane (R-116), 1,1-dichloro-1-fluoroethane (R-141b), 1-chloro-1,1-difluoroethane (R-142b), octafluoropropane (R-218), 1,1,1,3,3-pentafluoropropane (R-245fa), and fluoromethane (R-41). The 12 coefficients of the equations of state were fitted to substance specific data sets. The results show that simultaneously optimized functional forms can be applied to other fluids out of the same class of fluids for which they were optimized without significant loss of accuracy. The high numerical stability of the functional forms resulted in successful fits for fluids that previously could not be described by accurate empirical equations of state. For R-41, it is shown that the accuracies can be increased further by fitting the temperature exponents in addition to the coefficients of the equation of state, provided that highly accurate experimental data are available. Typical uncertainties of properties calculated using the new equations are 0.2 % in density, 1 % to 2 % in heat capacity and liquid-phase speed of sound, and 0.2 % in vapor pressure. Where data are available, uncertainties in vapor-phase sound speeds are generally less than 0.1 %.

“…The vapor pressure measurements of Kemp and Giauque (1937) and Robinson and Senturk (1979a) appear to be inconsistent by about 1 %. However, there is a temperature difference of 40 K between the upper limit of the Kemp and Giauque data and the lower limit of the Robinson and Senturk data.…”

Sulfur is a component of many industrially useful compounds, particularly process intermediates. Other sulfur compounds are important because of air pollution considerations, coming from natural sources (COS, SO 2 , H 2 S) as well as manmade. Carbon sulfides, carbonyl sulfide, thiophosgene, trichloromethanesulfenyl chloride, hydrogen sulfide, hydrogen polysulfides (sulfanes) and their salts, sulfur halides and oxyhalides, sulfur nitrides, sulfur oxides, sulfur oxygen acids and their salts, thiocyanic acid and its salts, methanesulfonyl chloride, and methanesulfonic acid are all discussed, along with properties, manufacture, shipment and storage, economic aspects, analytical methods, grades and specifications, health and safety, and uses in making agricultural pesticides, pharmaceuticals, food chemicals, oil additives, plastics and plastic additives, and refining catalysts. Elemental sulfur, sulfuric acid, sulfur trioxide, carbon disulfide, thiosulfates and sulfur removal from natural gas are discussed in separate articles in this Encyclopedia .
