| titleOfInvention | Method for producing 1-methyl-3-nitroguanidine |
| abstract | The invention relates to a method for producing 1-methyl-3-nitroguanidine, comprising the following steps: a) reacting chlorine cyanide or bromine cyanide with methylamine in the presence of an inert organic solvent at temperatures of -30 to 0 DEG C; then b) allowing the methylcyanamide formed in step a) to react directly with amoniumnitrate in a temperature range of 80 to 180 DEG C and a pressure range of between 1 and 50 bar, without further reprocessing; and c) dehydrating the methylguanidine nitrate formed in step b) after removing the solvent at temperatures of -20 to 60 DEG C; and d) finally, isolating the 1-methyl-3-nitroguanidine formed in step c). The inventive method provides a particularly environmently friendly and technically simple means of producing 1-methyl-3-nitroguanidine in yields of at least 85 % and with more than 98 % purity, from economical starting materials. |
