<p>Erythritol tetranitrate (ETN) - -  cousin of PETN, for which the detonation velocity of ETN is just above 8,000 meters per second - - while PETN det vel is about 8,300 meters per second plus, which is in the top 90% of highest velocity detonation velocities available from high explosives.<p>ETN is about 3 times more sensitive than PETN and is more sensitive to friction than the former mentioned compound. The decomposition of ETN is oxygen positive: C4H6N4O12 → 4 CO2 + 3 H2O + N2 + 3/2 O.<p>Why would any professional mess around with something that is 3x more sensitive than PETN ? Easier synthesis perhaps, but life changing or ending, if it detonates accidentally<p>PETN is the preferred explosive in the widely used "det cord", likely for a good reason, at 3x less sensitive.</p>

<p>Correction:<p>>How about 40 percent oxygen and 60 percent nitrogen? (Note: This is real stuff, >it's called Nitrox.)<p>As a nitrox certified diver I can offer that most common nitrox mixes do not exceed 34% oxygen and often are 32% oxygen.   For safety, a diver with 32% oxygen is typically limited to about 112 feet water depth, before potential oxygen toxicity sets in to the nervous system.<p>For safety a diver with 36% oxygen is limited to about 95 feet water depth.<p>A large majority of underwater reefs around the world are above these maximum nitrox depths.<p>Furthermore, nitrox is quite popular, especially among older divers as many seem to agree they have more energy near the end of a 2 tank or multiple tank dive day.<p>Using plain air and 2 tanks or more dives per day, it's been common to come back to the hotel and fall asleep to get a rest (or similar on liveaboards).<p>But using nitrox on all dives it's common for even the older crowd to have enough energy to be ready to go downtown to the bars and have some drinks after a day of diving.</p>
