TL;DR: The Langmuir method was used to determine the vapor pressures and heats of sublimation of several high melting organic explosives as mentioned in this paper, including cyclotrimethylene trinitramine (RDX), 48.0C; cyclotetramethylene tetranitramine, beta polymorph, 121.9C; 2,4,6- trinitroaniline (TNA), 44.8C; 1,3,5-triamino-2,4-6-trinitrobenzene (TATB), 131.6
Abstract: : The Langmuir method was used to determine the vapor pressures and heats of sublimation of several high melting organic explosives. The temperatures at which each compound would have a vapor pressure of 10 to the minus seven torr are: (1) cyclotrimethylene trinitramine (RDX), 48.0C; (2) cyclotetramethylene tetranitramine, beta polymorph, 121.9C; (3) 2,4,6- trinitroaniline (TNA), 44.0C; (4) 1,3-diamino-2,4,6-trinitrobenzene, form I polymorph, (DATB-I), 79.8C; (5) 1,3,5-triamino-2,4,6-trinitrobenzene (TATB), 131.4C; (6) 2,2',4,4',6,6'-hexanitrostilbene (HNS), 170.6C. Within a series those compounds which form the strongest intermolecular hydrogen-bonds have the highest heats of sublimation.

TL;DR: In this article, the solubility of cupric oxide, CuO, has been measured in pure water of pH 7.5 over the temperature range 50" to 550°C.
Abstract: THE DISSOLUTION, transport, and deposition of metallic oxides is an important factor in the operation of the high-pressure water circuit of modern power station boiler units. As feedwater purity improves, the relative importance of the metallic oxide impurities, which result largely from the corrosion of the water circuit containment itself, increases. A major parameter in each of the processes quoted above is the solubility of the oxide species in the high-temperature, high-pressure aqueous environment, but there is little data available for the systems of greatest practical significance, Fe304-H20, CuO-H20, and Cu20-H20. Sweeton et al. (8, 9) have studied the subcritical solubility of magnetite, Fe3O4, as a function of chloride ion concentration, while a small area of the supercritical solubility diagram for the system Fe304-H20 has been explored by Martynova (6). The measurements made by Pocock and Stewart (7) in the systems Cu-H20, Cu20-H20, and CuO-H20 were over a restricted range of pressure and temperature, and the results showed considerable scatter. In the present work, the solubility of cupric oxide, CuO, has been measured in pure water of pH 7.5 over the temperature range 50" to 550°C. and along a series of isobars between 3500 and 6000 p.s.i.g.
TL;DR: The extent of hydration of three primary alcohols in aqueous solution was determined by means of the difference between the fluidities measured at various concentrations and calculated by the Kendall equation as mentioned in this paper.
Abstract: The extent of hydration of three primary alcohols in aqueous solution was determined by means of the difference between the fluidities measured at various concentrations and calculated by the Kendall equation. These differences went through a single, pronounced maximum for each of the three binary systems, at compositions corresponding approximately to molar water-alcohol ratios of 3 to 2, 4 to 1, and 5 to 1 for methanol, ethanol, and 1 -propanol, respectively. These are the compositions
