    摘要： There are disclosed processes for destructing a toxic chemical including the steps of mixing the 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, the ionic liquid or molten salt comprising a tertiary amine group or quaternary ammonium group; and contacting the toxic chemical in the liquid phase with the ionic liquid or molten salt so as to decompose the toxic chemical.

    摘要： A method for dehalogenation detoxication of halogenated aromatic and/or cyclic compounds, based on the fact that at least one halogenated aromatic and/or cyclic compound is heated on a support matrix in a closed system at a temperature of 200 to 500° C. in the presence of copper in metallic form and/or in the form of copper compounds, a hydrogen donor, carbon and at least one additional reducing substance, capable of reducing cupric and cuprous ions to elemental copper at the above temperature.

    摘要： The subject invention provides a potentially economically viable method for the preparation of hydrogen peroxide (H2O2) in deep eutectic solvents (DES). H2O2 is then used for the destruction of small to large quantities of sulfur and nitrogen mustards and lewisite, their homologous/analogues, and similar chemical warfare agents at ambient conditions in DES without producing any toxic by-products. Furthermore, H2O2 has been used for the destruction of small to large quantities of halogenated hydrocarbons, their homologous/analogues, and similar hazardous chemicals at ambient conditions. H2O2 can be formed by either the electrochemical reduction of oxygen in DES in the presence of water or by dissolving Group 1 (alkali metals) or Group 2 (alkaline earth metals) superoxides, e.g. potassium superoxide, in DES in the presence of water, with/without chemicals used for the enhancement of the solubility of the metal superoxide in the DES, e.g. crown ethers.
