Reports of experimental determinations of solubility for 30 ternary systems of C4–C10 alcohols with hydrocarbons and water are exhaustively compiled and critically evaluated. Reports of experimental determination of solubility that appeared in the primary literature prior to the middle of 2012 are included. For seven systems, sufficient data (two or more independent desterminations) for critical evaluation are available. All data are expressed as mass percent and mole fraction as well as the originally reported units. In addition to the standard evaluation criteria used throughout the Solubility Data Series, two additional criteria were used for each of the evaluated systems. These systems include two binary miscibility gaps in the alcohol + water and hydrocarbon + water subsystems. The binary tie lines were compared with the recommended values published previously and with values obtained with a predictive NRTL model.
IUPAC-NIST Solubility Data Series. 102. Solubility of Nonsteroidal Anti-inflammatory Drugs (NSAIDs) in Neat Organic Solvents and Organic Solvent Mixtures43(2014); http://dx.doi.org/10.1063/1.4869683View Description Hide Description
Solubility data are compiled and reviewed for 33 nonsteroidal anti-inflammatory drugs dissolved in neat organic solvents and in well-defined binary and ternary organic solvents. The compiled solubility data were retrieved primarily from the chemical and pharmaceutical literature covering the period from 1980 to the beginning of 2014.
Reference Correlation of the Viscosity of n-Heptane from the Triple Point to 600 K and up to 248 MPa43(2014); http://dx.doi.org/10.1063/1.4875930View Description Hide Description
This paper contains a new wide-ranging correlation for the viscosity of n-heptane based on critically evaluated experimental data. The correlation is valid from the triple point (182.55 K) to 600 K, and at pressures up to 248 MPa. The estimated uncertainty at a 95% confidence level is 3.5% over the whole range (with the exception of the near-critical region). Along the saturated liquid curve, the estimated uncertainty is 1% below 292 K, 0.6% in the region from 292 to 346 K, rising to 2% between 346 and 363 K, and 0.3% for the low-density gas at temperatures from 317 to 600 K and pressures to 0.3 MPa.

Accurate correlations are given for the temperature dependence of the surface tension of 37 fluids included in NIST's REFPROP program. The surface tension of these fluids was not included in the most recent version of this program, V9.12. A set of data was constructed for each of these fluids by including principally the values given in the DIPPR, DETHERM, and TDE databases and Wohlfarth and Wohlfarth's book. For some fluids, other available sources of data were added in order to obtain adequate sets. The correlation expression used is the same as used for other fluids in REFPROP. For 31 fluids it was enough to use two adjustable coefficients, whereas four coefficients were needed for the other 6 fluids. For 19 fluids, the mean average percentage deviation was below 1%, and for another 16 it ranged from 1% to 2%.
