摘要： Described are methods for preparing salts of 5-nitrotetrazolate that include reacting aqueous solutions of 5-aminotetrazole, an acid, and sodium nitrite in a continuous flow system at an elevated temperature. The method shows the advantages over the methods based on cuprous salts as being less expensive, copper-free and safe at a large scale.
