Quebrachitol pentanitrate

Both esters, and specially hexanitroinositol, were suggested by Crater [71] for use in explosives practice instead of tetryl for filling detonators and boosters. In explosive strength, sensitiveness to mechanical shock, and stability both esters are similar to nitromannite. References to quebrachitol pentanitrate can be found in the patents of Burke and McGill [72]. 

Quebrachitol Pentanitrate (Nitroquebrachite). C6H6(0NO2)5.0CH3, mw 419.18, N 16.71%, OB to C02 —9.5%, bp (flashes on heating). Transparent, odorless, very viscous oil. Crater (Ref 5) prepd it by nitrating quebrachitol with mixed nitric-sulfuric acid, using the same technique as in the prepn of NG. After nitration was complete, the mixt was run into a separator, where Quebrachitol Pentanitrate sepd out in an oily layer which was skimmed off and drowned in cold w. The sticky syrup was dissolved in eth and neutralized by emulsifying with Na carbonate soln. The two solns were sepd by means of a separatory funnel, and the eth evapd off under vac... 

Quebrachitol Pentanitrate is nearly insol in w, difficultly in coned sulfuric acid and v sol in eth, methanol, ethanol and gl acet ac. It flashes without exploding when dropped on a hotplate, and detonates when struck with a hammer on a steel plate, or with a No 6 blasting cap...
