Conductivity sodium aluminum chloride

This cell reaction necessitates a sodium-ion-conductive electrolyte. At present, the best and most stable sodium ion conductor is j8"-alumina. This electrolyte has sufficiently high sodium ion conductivity at temperatures of about 300 °C. The S"-alumina electrolyte is normally designed as a tube, closed at one end, with a negative electrode on the outside and the positive electrode on the inside of the tube. The positive electrode, which consists of nickel chloride, nickel, and salt, throughout the reaction is incorporated in a nickel powder matrix and has a nickel current collector. The positive electrode is solid, as is the ceramic electrolyte therefore the soHd electrode must be made to work together with the soHd electrolyte, so that cell reactions can proceed. This is achieved by using a second electrolyte, sodium aluminum chloride, which is molten at the operating... 

Organophosphorus compounds find wide use in the chemical industry as catalysts, intermediates, complexes, and end-use products. Arylphosphines and phosphine oxides are often produced by the reaction of a preformed Grignard reagent with a halophosphine or phosphine oxide. Yields are reduced by the production of unwanted side-reaction products such as biaryls. These unwanted products are reduced when the reaction is conducted under Barbier conditions. When alkyl and aryl halides are reacted with magnesium metal, a trihalophosphine or phosphine oxide, a metal halide or amine catalyst, in THE benzene mixtures, at reflux, good yields of phosphines or phosphine oxides are obtained [74]. For example, triphenylphosphine can be prepared in a 97.2% yield from the reaction of bromobenzene, trichlorophosphine, magnesium metal, aluminum chloride, and sodium chloride in THF-benzene at 70 80 C. 

ALLILE (CLORURO di) (Italian) (107-05-1) Forms explosive mixture with air (flash point -20°F/-29°C). Violent polymerization and explosion may occur from elevated temperatures, light, acid catalysts, ferric chloride, aluminum chloride, Lewis acids, or Ziegler catalysts, finely divided metals. Violent reaction with oxidizers, alkyl aluminum chlorides. Incompatible with strong acids, oleum, amines, aluminum chloride, boron trifluoride, chloro-sulfonic acid, ethylene diamine, ethyleneimine, ferric chloride, sodium hydroxide. Slow decomposition with moisture. Attacks some coatings, plastics, and rubber. Corrosive to steel. Flow or agitation of substance may generate electrostatic charges due to low conductivity. 

BUTENE OXIDE (106-88-7) Forms explosive mixture with air (flash point -7°F/-22°C). Unless inhibited, violent polymerization can be caused by elevated temperatures, sunlight, acids, aluminum chlorides, bases, iron, tin, potassium, sodium, sodium hydroxide, or certain salts. Reacts violently with oxidizers, alcohols. Reacts with hydroxides, metal chlorides, oxides. Flow or agitation of substance may generate electrostatic charges due to low conductivity. Storage tanks and other equipment should be absolutely dry and free from air, ammonia, acetylene, hydrogen sulfide, rust, and other contaminants.
