Abstract
A method for gassing an emulsion explosives to sensitize the explosive to detonation and/or for density modification is described. The method comprises reacting a compound having an enol group, or a deprotonated enolate form of the enol group, with a nitrosating agent to generate nitric oxide to gas the explosive. The compound reacted with the nitrosating agent can be a lactone such as ascorbic acid. Dinitrogen trioxide is particularly useful as the nitrosating agent.
