Solubility of glycine, leucine, and tyrosine in liquid ammonia.
Tank liquid ammonia (Ohio Chemical and Manufacturing Company) was distilled from sodium shavings into a tube of about 120 cc. volume. This was equipped with a thermocouple well, inlet and outlet side arms protected with calcium chloride and phosphorus pentoxide drying towers, and a standard taper cap containing a mercury seal stirrer. A current of dry nitrogen could be passed through the tube, ...
متن کاملSolution Phenomena in Liquid Ammonia
An extended discussion of solution phenomena in anhydrous liquid ammonia is presented. The solvent properties of ammonia for various classes of compounds is discussed in terms of its hydrogen bonding ability, moderate dielectric constant, elatively high basicity, and high dipole moment. In general, ammonia is a better solvent than water for covalent molecules, but a poor solvent for ionic speci...
متن کاملp-Si, and n-Ti02 in Liquid Ammonia
The behavior of several nand p-type semiconductors in liquid ammonia with 0.1 M KI as supporting electrolyte was investigated. The flat-band potentials were estimated from Schottky-Mott plots, and the current-potential curves with several redox couples (e.g., benzophenone, naphthalene, nitrobenzene) in the dark and under illumination were obtained. Photoinjection of solvated electrons at p-GaAs...
