Abstract
Abstract A method is disclosed for preparing new N-nitro-N-lower alkyl glucamine pentanitrates. These new compounds possess explosive characteristics similar to pentaerythritol tetranitrate (PETN) and may be similarly employed in explosive devices such as primers, boosters and explosive initiators.
