“…The frequency assignment used in the calculations of these tables agrees closely with one previously given [24,25]. The value of 700 em-I, there assigned to the OOH angle frequency, was based on earlier papers on methyl alcohol.…”

Thermodynamic functions including free energy, enthalpy, entropy, and specific heat, are given for the compounds butadiene, benzene, cyclonexane, etnane, etnylene, etnyl alcohol and water and for the elements carbon (graphite), hydrogen and oxygen. From these are calculated and tabulated values of equilibrium constants for reactions of interest in connection with the production of 1,3-butadiene for synthetic rubber. Comparisons are made between table values and available experimental data on equilibrium constants, gaseous specific heats and entropies. The cracking of hydrocarbons is discussed and the importance of reaction rates in determining the amounts of reaction products is noted.

Values of equilibrium composition for the hydration of ethylene to form ethanol have been calculated for a series of elevated pressures and temperatures by using equilibrium data available from previous low-pressure studies. To obtain satisfactory agreement between these values and those measured experimentally, it is essential (I! to take into account the formation of ethyl ether and (2) to use available vapor-liquid equilibrium data for the binary ethanol-water system at elevated temperatures, instead of the standard "mixture rules" often employed.Thermochemical data and low-pressure equilibrium data for both the ethylene hydratiod and ether formation reactions are critically reviewed. Experimentally measured values for the equilibrium concentrations of ethanol and ether in the liquid phase at 221°C. and 273 atm., with dilute sulfuric acid used as catalyst in a lined rocking-bomb reactor, are presented.

“…In addition, there are three O-C-C bending vibrations, which were assumed to have the same frequencies as ethanol. 29 The barrier heights for the hindered rotations at each end and the middle of each n-butyl group were taken from Herzberg 30 and Morrison and Boyd, 31 respectively. The hindered rotations of the three end methyl groups were assumed to be rotations of symmetrical tops connected to a rigid frame.…”
