Abstract: An aqueous water repellent composition comprising the reaction product of one or more of a carboxylic acid or anhydride containing from 3 to 22 carbon atoms and a polyfunctional aromatic or aliphatic amine or substituted amine containing from 2 to 25 carbon atoms and a water soluble metal complex crosslinking agent containing one or more metals selected from Groups Ia, IIa, IIla, IVa and the first and second rows of transition metals from the Periodic Table of Elements. The composition may contain wax and is dispersed in water to form a water repellent system.

Abstract: A preservative element, for timber or masonry in the form of a shaped element containing an organic boron compound, especially a boro-organic ester. Preferably the element also contains inorganic boron salts or acids, with or without the addition of other inorganic compounds having fungicidal and/or insecticidal properties.

Abstract: A promoter for improving the adhesion of rubber to metals is obtained by reacting an alkaline earth borate such as calcium borate with a cobalt or nickel carboxylate. Preferred carboxylates contain 3-24 carbon atoms.

Abstract: A process for the direct recovery of tin, as an organo hydrocarbyl tin compound, from reduced but unrefined tin ores and ore slags is described, wherein the ore is reacted directly with a hydrocarbyl halide to form an organo hydrocarbyl tin compound which can then easily be removed and separated from the tin-depleted ore residue.

Abstract: Oxo-aluminum complexes prepared by reacting a substituted aluminum alkoxide with a molar deficiency of water or carboxylic acid. The complexes are useful in surface coating compositions based on synthetic resins such as alkyd resins.

Abstract: A process is disclosed for the direct production of organotin halides, particularly triorganotin halides by the reaction of elemental tin and an organotin halide in the presence of a reagent amount of an `onium compound of the general formula Cat.sup.+ X.sup.-. Cat.sup.+ X.sup.- may represent a quaternary ammonium or phosphonium group or a ternary sulphonium group, or may also represent a complex of an alkali metal or alkaline earth metal with a polyoxygen compound. High yields of triorganotin halide product are obtained in contrast to results of reactions wherein Cat.sup.+ X.sup.- is present in only catalytic amounts.

Abstract: The apparatus of this invention comprises an electrolysis cell with an electrolyte system having at least two phases, one of which is aqueous while another is aqueous immiscible, and wherein the inter-facial current passage is ionic rather than electronic.

Abstract: A method and apparatus are described for electrolyzing a tin-containing electrolyte using an electrolysis system having at least two immiscible electrolyte phases and wherein the electric current is passed between electrodes respectively disposed solely in one of the electrolytes. More than two electrolytes may be used.

Abstract: An electrolysis system and method are disclosed having at least two electrolyte phases, one of which is aqueous and another of which is aqueous-immiscible wherein the inter-facial current passage is ionic rather than electronic. Electrode contact with such electrolytes is limited to a single electrolyte for each electrode. The system can be used for the production of elemental metals from compounds containing the same, for the purification of impure metals, and for the conducting of electrolytic redox reactions with water-immiscible species.

Abstract: Fungicidal compositions comprising at least one organometallic compound of aluminum and/or boron, at least one divalent metal and at least one carboxylic acid group. The compositions are useful in preserving timber.

Abstract: Method for preparing storage-stable air-drying compositions containing a combination of an aluminum alkoxide with a labile monofunctional reactant such as an alkanol, alkoxyalkanol, keto ester, water, hydrogen peroxide, organic hydroperoxide or mixtures thereof.

Abstract: Compounds comprising three atoms of a divalent metal linked through oxygen atoms to an atom selected from the group consisting of a boron atom, a phosphorus atom and a phosphorus atom bonded to an oxo oxygen, and an aliphatic monocarboxylic acid radical attached to each divalent metal atom, at least one of said aliphatic monocarboxylic acid radicals having from 7 to 9 carbon atoms, and at least one other of said aliphatic monocarboxylic acid radicals having 10 or 11 carbon atoms, and the polymerization products thereof, are useful as rubber compound adhesion promoters and are more easily handled than the previously known compounds and polymers used for this purpose.

Abstract: Metal complexes prepared by the reaction of less than one mole of an alkanolamine with at least one mole of a metal alkoxide and a polyhydric alcohol. The complexes are useful for imparting thixotropy to systems containing protective organic colloids.
