Abstract

Un método para preparar sales de 5-nitrotetrazolato que comprende hacer reaccionar disoluciones acuosas de 5- aminotetrazol y un ácido como una primera corriente reaccionante (12), y un nitrito como una segunda corriente reaccionante (14) en un sistema de flujo continuo (10) a una temperatura elevada en un intervalo de aproximadamente 50°C a 100°C, caracterizado por que el sistema de flujo continuo comprende una zona calentada (18) que se mantiene a la temperatura elevada, comprendiendo la zona calentada (18) una zona de precalentamiento (20, 22) para cada corriente reaccionante (12, 14), una zona de mezcla (24) que combina la primera corriente reaccionante (12) y la segunda corriente reaccionante (14) en una mezcla reactiva, y una zona de reacción (28) que está configurada para retener la mezcla reaccionante en la zona calentada (18) hasta que se completa la reacción.
