Abstract

La présente invention concerne une solution génératrice de gaz destinée à sensibiliser une émulsion de manière à obtenir une composition explosive qui contient une émulsion gazée et qui possède une phase aqueuse discontinue. Cette phase aqueuse comprend des sels non organiques libérant de l'oxygène, une phase organique continue non miscible dans l'eau ainsi qu'un émulsifiant. L'émulsifiant comprend une tête polaire possédant un fragment fonctionnel vulnérable aux attaques provenant d'une espèce chimique de type nitroso. La solution génératrice de gaz comprend également une solution se composant d'un nitrite non organique, d'une espèce chimique de type ammonium et, éventuellement, d'un accélérateur.
