摘要： A low temperature molten ionic liquid composition comprising a mixture of a metal halide and an alkyl-containing amine hydrohalide salt is described which is useful as a catalyst and a solvent in alkylation, arylation and polymerization reactions or as an electrolyte for batteries. The metal halide is a covalently bonded metal halide which can contain a metal selected from the group comprised of aluminum, gallium, iron, copper, zinc, and indium, and is most preferably aluminum trichloride. The alkyl-containing amine hydrohalide salt may contain up to three alkyl groups, which are preferably lower alkyl, such as methyl and ethyl.

摘要： Process for preparing dry fast-setting, magnesium phosphate cementitious composition capable of setting to a hardened mass at ambient temperatures following the addition of water thereto is disclosed. In this process unfiltered superphosphoric acid is added to a mixture of a magnesium-containing compound, e.g. MgO, and an aggregate, e.g. silica, with cooling to form a dry powder. This dry powder can be stored without caking, and forms a fast-setting cement having commercially acceptable compressive strength in the presence of water.

摘要： A process for applying an aqueous mixture of a magnesium phosphate cementitious material to a base material in which the resulting bond between the materials is improved. In this method the base material is coated with a passivating agent capable of reducing the pH of the surface of the base material prior to applying the aqueous mixture of magnesium phosphate cementitious material. The base material can be a hydraulic cementitious material, e.g., Portland cement. The cementitious material is magnesium phosphate quick-setting cement. Preferred passivating agents can be aluminum acid phosphate, magnesium acid phosphate, aluminum sulfate, ammonium polyphosphate, phosphoric acid, an activator and mixtures thereof. The resulting laminated structure composed of the base material, the coating and the magnesium phosphate cementitious material is also disclosed.

摘要： A process for reforming a hydrocarbon which comprises treating the hydrocarbon, while at elevated temperature, with a transition metal catalyst while in the presence of an effective amount of gaseous oxygen to improve the selectivity of the catalyst to aromatic formation and reduce the hydrogenolysis activity of the catalyst. The transition metal may be tungsten, and the transition metal catalyst may be supported on an oxidic support, optionally with a ceramic passivation layer lying between the support and the transition metal catalyst. The amount of gaseous oxygen used may be from about 50 ppm to about 5000 ppm, based upon the weight of the hydrocarbon.
