The enthalpy of formation and absolute entropy of AlH3 at 298.15°K have been measured as −2.73±0.20 kcal/mole and 7.18±0.10 cal/(mole·°K), respectively. The derived Gibbs energy of formation at 298.15°K of 11.11±0.23 kcal/mole indicates AlH3 is unstable with respect to decomposition to the elements.

The thermodynamic tabulations previously published as NSRDS-NBS-37 are extended by 154 new and revised tables. The JANAF Thermochemical Tables cover the thermodynamic properties over a wide temperature range with single phase tables for the crystal, liquid, and ideal gas state. The properties given are heat capacity, entropy, Gibbs energy function, enthalpy, enthalpy of formation, Gibbs energy of formation, and the logarithm of the equilibrium constant for formation of each compound from the elements in their standard reference states. Each tabulation lists all pertinent input data and contains a critical evaluation of the literature upon which these values are based. Literature references are given.

At temperatures above 830°K, the thermally initiated reaction of CF3CN reversibly yields C2F6 and C2N2. Equilibrium constants were determined in the temperature range 865-925 °K and a reaction enthalpy of -

The thermal behaviors of latexes were studied by using MicroCal MC-2 Scanning Calorimeter which is a differential scanning micro-calorimeter capable of handling fluids under pressure. The MC-2 unit was found to be uniquely capable of measuring not only the glass transition temperatures (Tg's) of wet latexes, but also the extent of annealing (enthalpy relaxation) that has a profound impact on the deformability of latex particles and, in turn, the film formation of latexes. The effects of polar monomers, the neutralization of carboxylated latexes, and coalescing agents on the wet latex Tg's were also studied.
