Elastic Constants of Plastic Crystals by Schaefer-Bergmann Scattering: Crystalline Cyclohexane and Deuteromethane
The Schaefer-Bergmann technique for sound velocity measurement has been adapted for use with solidified liquids and gases. The advantages of this method for measuring elastic constants of plastic crystals are discussed. A method for determining both the elastic constants and the spacial orientation …

The Preparation of: 1. 1-(p-Methoxyphenyl)-2,6-dicarbethoxy-5-amino-cyclohexenone-3. 2. 1-(p-Methoxyphenyl)-2,6-dicarbethoxy-4-cinnamoyl-cyclohexane-dione-3,5. 3. diidodo derivative of 1-(p-Hydroxyphenyl)-2,6-dicarbethoxy-cyclohexane-dione-3,5.
For this type of reaction to tabs place, the methylene group requires the activating influence of an adjacent CC, -CN, or -NO2 grouping. A heterocyclic, or an aromatic group, or a conjugated system have the same effect.

Adsorption of binary vapor mixtures into solids
The adsorption isotherms for ethanol-cyclohexane, ethanol-benzene, and benzene-cyclohexane vapor mixtures on Cab-O-Sil and on Graphon at 20, 30, and 40°C were measured at constant total pressure. The adsorption isotherms for the pure components were also obtained. The ethanol/Graphon isotherms were …
