[origin: WO0146129A2] The invention relates to a method for producing nitroguanidine. According to the inventive method, guanidine nitrate or guanidine carbonate a dehydrated in a first step with high concentration nitric acid (> 85 %). The nitroguanidine nitrate formed is hydrolyzed in a second step with water to give nitroguanidine and nitric acid. The concentration of the nitric acid produced in the hydrolysis must not exceed 25 %.
