After successful synthesis of hexabenzylhexaazaisowurtzitane (HBIW) on a laboratory scale (0.25 L reactor), it was performed on a multilaboratory scale (10 L reactor) and subsequently in an experimental installation in which a 300 L reactor was built. Seven syntheses were carried out in the unit on a pilot scale to produce 250 kg of HBIW. The pilot-scale syntheses ran with a yield comparable to those observed for the processes conducted on a large-laboratory scale. Some modifications were suggested that allowed for reduction of the HBIW weight unit by approximately 50%.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
