Please continue be pedantic. Forces us to provide rationale. This does not match my (mil) experience of typical composition of industrial dynamite, so went to wiki: "The most common composition of dynamite consists of three parts nitroglycerin, one part diatomaceous earth and a small admixture of sodium carbonate." And the same wiki article provides a similar comp to my original description of (mil) dynamite: " Military dynamite is a dynamite substitute, formulated without nitroglycerin. It contains 75% RDX, 15% TNT, 5% SAE 10 motor oil, and 5% cornstarch..."
So added up the available bonds (data from CRC), RDX+glycerines+oil, bond energy releases about 5-6kJ/mole, so my original 1MJ/stick for mil stuff probably approximately 50% lower than an industrial stick of similar volume and mass. You people really should not be distracting me like this, have two reports due this week...

TNT is 2,4,6-trinitrotoluene. Dynamite is nitroglycerine stabilized with diatomaceous earth. It has about 25% more energy per gram than TNT. The names of these two explosives are often used when describing other chemistries, but the technically refer to a specific chemistry each. Completely uses information: Dynamite was invented by Alfred Nobel who invented a number of other explosives. After being called "the merchant of death", he decided to rewrite his will to create the Nobel Prizes in an effort to leave behind a better legacy.

TNT is NOT the composition of industrial or military 'dynamite'. Typical dynamite, at least the stuff we played with, is cornstarch binders +oil +TNT+RDX; and there were some compositions that were buffered with sodium carbonate. Dynamite, depending on the size of the stick and intended end-use, will contain well under 20% TNT by both mass and volume. Mechanical/chemical stabilization and reaction rates are more controlled in modern 'dynamite. For large construction and mining stuff, dynamite yields poor results, so tends to be limited to use for ignition of an oil+ammonium nitrate bulk-type explosive.

Not the answer, but may be useful: 4,184,000,000 J = 1 ton of TNT For a comparison of energy in dynamite and gasoline, and for "The nonsense about gasoline and dynamite," see: https://na01.safelinks.protection.outlook.com/?url=http:%2f%2fhome.earthlink.net%2f~jimlux%2fenergies.htm%23GasDynamite&data=01%7C01%7Cted.eckert%40MICROSOFT.COM%7Cf68f2908cbfb420f617d08d33983456c%7C72f988bf86f141af91ab2d7cd011db47%7C1&sdata=07tKgMtH%2bPCj2UyjJPHgAI%2bR9h2fvjcXs0xODGurmaU%3d Rich > -----Original Message----- > From: Macy [mailto:[email protected]] > Sent: Friday, February 19, 2016 9:59 AM > To: [email protected] > Subject: [PSES] Energy in certain items > > Does anyone know the energy [joules] in a standard stick of dynamite, > or a gallon of gasoline? - ---------------------------------------------------------------- This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
