Good morning campers, well PF members.
Although my question is needed my homework I am also interested in the history of what I will ask, hence the reason it is in the chemistry section.
I also ask that mentors do not close this thread as I should only be talking about gunpowder to TNT, which can be found on the interent if one looks (and so will make no difference if I ask questions about the history of them here).
It appears I have a gap in my history of the develpoment of explosives. I can say that gunpowder (or black powder) was invented by the Chinese in about the 10th century (although looks of web sites say different centuries but this accuaracy is not too imporant). The explosive made its way to Europe in about the fourteenth century and was used in battle. Problem with it was the smoke.
1846 and 1847 saw two inventions/discoveries. One was nitrocellulose and the other was nitroglycerine. Both unstable and dangerous. However, both solved the problem that gunpowder had: they were smokeless.
Mixing the two together with petrolatum and adding propanone in the final stages create cordite. I believe this invented in the 1880s.
Then not too much really happened, well minus two World Wars.
Then it was the turn of Nobel to invent dynamite sticks in 1867. This is where my problem comes in.
Nobel used nitroglycerine but it did not seem to come from cordite (obvious as the dates do not make this possible). Am I to believe that Nobel invented dynamite without the knowledge of nitrocellulose and used nitrogylcerine to make dynamte? If so, why was cordite invented? I see no reason for it to be manufactured when dynamite was around. Finally, what is the chemical formula for kieselguhr (it was used to make nitrogylcerine safe)?
Thank you very much
I know the question sounds stupid but I cannot find the answer anywhere. I would assume but I am not that sort of person.
