Mannitol Hexanitrate
Mannitol hexanitrate is a powerful explosive. Physically, it is a powdery solid at normal temperature ranges, with density of 1.73 g/cm3. The chemical name is hexanitromannitol and it is also known as nitromannite, MHN, and nitromannitol, and by the trademarks Nitranitol and Mannitrin. It is more stable than nitroglycerin, and it is used in detonators. Mannitol hexanitrate is a secondary explosive formed by the nitration of mannitol, a sugar alcohol. The product is used in medicine as a vasodilator and as an explosive in blasting caps. Its sensitivity is high, particularly at high temperatures (> 75 °C) where it is slightly more sensitive than nitroglycerine. Nitromannite is a class B explosive. The production of pure MHN is not a trivial task, since most preparations will yield a mixture of MHN and lower esters (pentanitrate and lower). See also * Pentaerythritol tetranitrate (PETN) * Xylitol pentanitrate * Erythritol tetranitrate (ETN) * Ethylene glycol dinitra ...

National Historical Museum (Argentina)
The Argentine National Historical Museum ( es, Museo Histórico Nacional) is located in Buenos Aires, Argentina, and is a museum dedicated to the history of Argentina, exhibiting objects relating to the May Revolution and the Argentine War of Independence. History The institution was established as the ''Museo Histórico de la Capital'' (Historical Museum of the Capital) by Mayor Francisco Seeber on May 24, 1889. The museum resulted from a proposal by historian Adolfo Carranza, who was designated director of the museum upon its inauguration on February 15, 1891. The museum was initially located on government property located at 3951 Santa Fe Avenue (now occupied by the Buenos Aires Botanical Garden). It was relocated to its present location in the San Telmo ward after the land's purchase by the Municipality of Buenos Aires in 1897. The land later occupied by the Botanical Garden was thus transferred to the municipal government, and the museum to the national government. Th ...
