  • Method of preparing salts of dinitromethane
    Patent number: 6340780
    Abstract: A method of preparing dinitromethane salts usable as intermediate products add starting material for production of explosives and propellants. Substituted 1,2-diazoles, 1,2,4 -triazoles or 1,3-diazines, such as barbituric acid, are nitrated to obtain a gem-dinitro group on a carbon atom in the heterocyclic ring. The product is hydrolysed to split off dinitromethane which is neutralised with a neutralising agent to obtain a corresponding salt of dinitromethane.
