89 results about "Nitrogen mustard" patented technology

Nitrogen mustards are cytotoxic chemotherapy agents derived from mustard gas. Although their common use is medicinal, in principle these compounds can also be deployed as chemical warfare agents. Nitrogen mustards are nonspecific DNA alkylating agents. Nitrogen mustard gas was stockpiled by several nations during the Second World War, but it was never used in combat. As with all types of mustard gas, nitrogen mustards are powerful and persistent blister agents and the main examples (HN1, HN2, HN3, see below) are therefore classified as Schedule 1 substances within the Chemical Weapons Convention. Production and use is therefore strongly restricted.

Method for the preparation of reactive compositions containing hydrogen peroxide

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.
