Abstract

Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von Nitroguanidin, bei dem in einer ersten Stufe Guanidinnitrat oder Guanidincarbonat mit Hoko-Salpetersäure (> 85 %) dehydratisiert wird und das sich bildende Nitroguanidinnitrat in einer zweiten Stufe mit Wasser zu Nitroguanidin und Salpetersäure hydrolisiert wird wobei die Konzentration der sich bei der Hydrolyse bildenden Salpetersäure 25 % nicht übersteigen darf.
