Abstract: Compounds, synthesis of, and methods for synthesizing metal alkoxide derivatives; and metal alkoxide derivatives for use as flame retardants are described. Group 13 metal alkoxides having flame retardant properties may be prepared by reacting the periodic table group 13 metalloid or metal trihydroxide with an alcohol.

Abstract: Stabilized alumoxane solutions are provided as well as a method for producing such solutions. The method generally involves the use of metallocene catalyst component(s) that when mixed with alumoxane solutions reduce the tendency for such solutions to form gels.

Abstract: Aluminoxanes are used as activators for the gas, solution or slurry phase polymerization of olefins in the presence of single site catalysts. Aluminoxanes contain residual aluminum alkyls which may poison the catalysts. The residual aluminum alkyls may be bound an/or removed from the aluminoxanes by treatment with carbohydrates such as cellulose, starch or sugar.

Abstract: Alumoxane, and especially methylalumoxane, which provide supported metallocene and/or transition metal catalyst compositions having increased activity are prepared by heating the alumoxane prior to placing it on the support.

Abstract: A aluminoxane product is prepared by reacting water which contains a stabilizing agent, such as a lithium halide, with a hydrocarbyl aluminum compound, such as trimethylaluminum, in an organic solvent.

Abstract: The invention concerns a method of preparing preferably highly concentrated aluminum triformate solutions containing alkali metals and/or alkaline earth metals, by the neutralization of an alkaline aluminate solution containing alkali metals and/or alkaline earth metals by adding formic acid, and subsequently heating the solid precipitated to give a clear, stable aluminum triformate solution. The invention also concerns highly concentrated aluminum triformate solutions containing alkali metals and/or alkaline earth metals and the use of such solutions to impregnate textiles, in disinfectant and cleaning agents, as a coagulant for paints, or as a setting agent in leather processing.

Abstract: Novel primary and secondary amino-aluminoxane derivatives are prepared by reacting an aluminoxane and a primary or secondary amine in an organic solvent, heating the reaction mixture to form a homogeneous solution and filtering the solution.

Abstract: Tertiary amine alanes are produced by reacting sodium aluminum hydride and magnesium dichloride. A tertiary amine is admixed to extract the tertiary amine alane. Stoichiometric ratios of sodium aluminum hydride to magnesium dichloride can be varied to effect the magnesium compound by-product produced.

Abstract: A process for preparing a submicron antiperspirant adduct. The process begins by dissolving a mixture of an aluminum-containing salt and a steric stabilizer in a solvent. The antiperspirant salt is then precipitated into the steric stabilizer. The resulting adduct of submicron size can be dispersed into a cosmetic carrier or otherwise processed.

The amine alane product can be reacted with a silicon halide to prepare silane.

Abstract: Amine alane decomposition is catalyzed by titanium. This effect of titanium can be suppressed by treating it with a passivating agent such as air, nitrous oxide, carbon monoxide and alkyl nitrites. Such agents may be used (1) to treat titanium-containing NaAlH.sub.4 preparations to be used in preparing amine alanes, or (2) to treat amine alanes containing titanium as an impurity, e.g. in finely divided form. Furthermore, the reaction of NaAlH.sub.4, amine, and a halide substance to produce an amine alane can be conducted in the presence of a passivating agent.

Abstract: A process is disclosed for reducing the solidification tendency of a normally solid lower aluminum alkoxide having 2 to 5 carbon atoms in the alkoxide radical. One embodiment comprises the steps of adding the aluminum alkoxide and a specific phosphorus compound to a common solvent, and forming a solution; and then extracting the common solvent to form a stabilized liquid. The phosphorus compound has an unblended structural formula ##STR1## wherein X, Y and Z are selected from (a) alkoxy groups containing from one to 12 carbon atoms; (b) alkyl groups containing from one to 14 carbon atoms; (c) aryloxy groups containing from 6 to 12 carbon atoms; (d) alkyl-substituted aryloxy groups wherein an alkyl group containing from one to 14 carbon atoms is substituted for a hydrogen atom; (e) alkyl-substituted aryloxy groups containing from 7 to 26 carbon atoms; and (f) aryl-substituted alkyl groups containing from 7 to 26 carbon atoms. Preferred processing conditions and products thereby obtained are also disclosed.
