摘要:
A method of deactivating an explosive composition provided in an explosive cartridge, which method comprises exposing the explosive composition to a deactivating agent that renders the explosive composition insensitive to detonation, wherein the deactivating agent is a chemical.
摘要:
The present invention relates generally to the destruction of chemical weapons. In particular, the present invention relates to methods for treating hydrolysates of chemical agents. In one embodiment, the present invention provides a method comprising oxidizing a hydrolysate of a chemical agent to produce an aqueous layer and an organic layer, the aqueous layer comprising an organophosphorus concentration and the organic layer comprising an organosulfur concentration, and separating the organic layer from the aqueous layer.
摘要:
A method of decomposing fluorine compounds, wherein a gas flow containing said fluorine compounds is brought into contact with a catalyst in the presence of steam at a temperature in the range of 200 to 800°C to decompose the fluorine compounds to hydrogen fluoride, wherein
said fluorine compounds comprise a compound of fluorine and carbon, a compound of fluorine, carbon and hydrogen, a compound of fluorine, carbon, hydrogen and oxygen, a compound of fluorine and nitrogen and/or a compound of fluorine and sulphur, and said catalyst contains aluminium oxide and at least one of the elements Ti, Fe, Sn, Co, Zr, Ce, Si and Pt; said Ti, Fe, Sn, Co, Zr, Ce and Si being in the form of an oxide or of a complex compound with Al.
摘要:
A method for disposing of waste generated during the manufacture, packaging and use of P4S10 by preparing an alkaline solution of said waste and biologically oxidising said solution.
摘要:
A method is provided for oxidising and/or hydrolysing halogenated organic compounds comprising contacting a mixture of the halogenated organic compound, excess oxygen, and-, optionally, water, with a carbonaceous catalyst under mild reaction conditions. The temperature of the reaction is typically below 400°C and the catalyst may be doped with acidic redox-active metal compounds.
摘要:
Es wird ein Verfahren zur Aufarbeitung von Rückständen beschrieben, welche bei der Destillation von Chlorsilanen anfallen, wenn diese durch Umsetzung von Rohsilicium mit Chlor oder Chlorwasserstoff hergestellt werden. Die Rückstände werden in wäßriger Phase mit einem Überschuß von mindestens 15 % an Calcium-Basen (CaO bzw. Ca(OH)₂) oder Calciumcarbonat behandelt. Hierbei werden die flüssigen Bestandteile in den Prozeß zurückgeführt, so daß kein Abwasser entsteht.
摘要:
A method of destructing a toxic chemical, comprising the steps of mixing said toxic chemical with a liquid phase formed by an aqueous mixture of water and an ionic liquid or molten salt which is miscible with water, said ionic liquid or molten salt comprising a tertiary amine group or quaternary ammonium group; and contacting said toxic chemical in said liquid phase with said ionic liquid or molten salt so as to decompose said toxic chemical. The ionic liquid or molten salt comprises a tertiary amine group or quaternary ammonium group. The dispersion or solution further contains at least one oxidizing agent and a donor of hydrogen bonds. Decontamination of contaminated surfaces and decomposition of toxic substances are achieved by using environmentally friendly, non-toxic solvents and reactants which yields reaction products which are substantially non-harmful or even non-toxic.
