Abstract
A method for synthesizing the alkali metal salts of dinitromethane by effecting the direct nitration of methyl malonate followed by the step of saponifying the nitrated reaction product.
Claims5
A method for synthesizing the alkali metal salts of dinitromethane which comprises the steps of
- (A) effecting a reaction between methyl malonate and a nitrating agent to produce methyl dinitroacetate;
- and
- (B) reacting the resulting methyl dinitroacetate reaction product with an aqueous solution of an alkali metal hydroxide at a temperature of from about 65.degree. C. to 85.degree. C. for a period of time sufficient to produce an alkali salt of dinitromethane.
