The invention relates to a method for producing 1-methyl-3-nitroguanidine. According to said method, nitroguanidine is reacted with methylamine and/or a methylammonium salt in an aqueous solution, at temperatures of 30 to 60° C. and at a pH value of 9.5 to 12.3. In this way, yields of 1-methyl-3-nitroguanidine of at least 80% and degrees of purity >99% can be obtained in a particularly environmentally friendly and technically simple way.
这项发明涉及一种生产1-甲基-3-硝基胍的方法。根据该方法,硝基胍与甲胺和/或甲铵盐在水溶液中反应,在30至60°C的温度和9.5至12.3的pH值下。通过这种方式,可以以至少80%的产率和>99%的纯度获得1-甲基-3-硝基胍,这是一种特别环保和技术简单的方法。
