Abstract
A process for synthesizing the alkali metal salts of dinitromethane by effecting the saponification of methyl cyanodinitroacetate previously prepared by the nitration of methyl cyanooximinoacetate.
Claims4
A process for preparing the alkali metal salts of dinitromethane which comprises the steps of
- (A) effecting the nitration of methyl cyanooximinoacetate to produce methyl cyanodinitroacetate;
- (B) effecting the hydrolysis of the resulting cyanodinitroacetate to produce dinitroacetonitrile;
- (C) effecting the neutralization of said dinitroacetonitrile with an alkali metal hydroxide to produce the corresponding alkali metal salt of cyanodinitromethide;
- and
- (D) effecting the saponification of said cyanodinitromethide salt with an aqueous solution of an alkali metal hydroxide at a temperature and for a time period sufficient to produce the corresponding alkali metal salt of dinitromethane.
