What are the chemicals used to make gun powder?
97523
Gunpowder, whether black powder or smokeless powder, is a substance that burns very rapidly and is used as a propellant in firearms. As it burns, a subsonic deflagration wave is produced rather than the supersonic detonation wave which high explosives would produce. This reduces peak pressures in a gun, but makes it less suitable for shattering rock or fortifications.\n\nBlack powder is a mix of sulphur, charcoal, and potassium or sodium nitrate, (sodium nitrate makes a less powerful compound), at a weight ratio of approximately 10:15:75, respectively, though the ratios can vary somewhat depending on the purpose of the powder. Unlike smokeless propellants, it acts more like an explosive since its burn rate is not affected by pressure, but it is a very poor explosive because it has a very slow decomposition rate and therefore a very low brisance. This same property that makes it a poor explosive makes it useful as a propellant — the lack of brisance keeps the black powder from shattering the barrel, and directs the energy to propelling the bullet. Historically, potassium nitrate was extracted from manure by a process superficially similar to composting. Nitre beds took about a year to produce crystallized potassium nitrate.

muzzle, at which point there is no more force pushing the projectile and the point which air starts to slow the projectile down.\n\nblack powder burns slowly the length of the barrel, pushing the projectile with increasing speed until it leaves the barrel.\n\nSmokeless powder burns rapidly.

BE VERY CAREFUL, then you can follow the instructions on the website: http://chemistry.about.com/cs/howtos/ht/gunpowder.htm\n\nDon't get into any trouble!

Hi, thats quite a difficult one. \n\nI will tryto give you what i can.\n\nyou can start with wikipedia. Thats because it gives things in the right sequence and then there are a lot of links.\n\nIn general, it describes a term Forensic Chemistry. Forensic chemistry applies the principles of chemistry to law enforcement. Some forensic chemists may deal with explosives or poisons. The bulk of most forensic chemists work is on the analyses of controlled substances. According to federal and state laws an accurate net weight and positive identification of a substance must be obtained before a person can be tried for its possession, distribution or manufacturing. State and local regulations can vary, but in general an analysis must be accomplished based on certain weight criteria. After the weight is obtained the chemist may perform presumptive testing using chemical reagents that cause a color or odor change. The result of the presumptive tests give the chemist clues that guide what type of further testing is required.\n\n\nSee more at :\nhttp://en.wikipedia.org/wiki/Forensic_chemistry\n\nYou will find a lot of links here, eg to Gas chromatography-mass spectrometry etc.\n\nSometihng to read here:\nhttp://www.keele.ac.uk/undergraduate/prospectus/2006/forensic.htm\n\nhttp://www.aafs.org/yfsf/newsletter/Sept2001/Goodpaster.html\n\nhttp://www.forensic-science-society.org.uk\n(The official web site of The Forensic Science Society.)\n\nMore useful links at:\nhttp://www.keele.ac.uk/depts/forensic/resources.htm\n\nYou will find links to a few people who you can write to. \nhttp://www.enfsi.org/search?SearchableText=chemistry&Title=&Description=&created%3Adate=1970%2F02%2F01+00%3A00%3A00+GMT&created_usage=range%3Amin&pt_toggle=%23&portal_type%3Alist=Collector&portal_type%3Alist=Collector+Catalog&portal_type%3Alist=Collector+Issue&portal_type%3Alist=Collector+Issue+Transcript&portal_type%3Alist=Collector+Subset&portal_type%3Alist=ContactFolder&portal_type%3Alist=ContentPanels&portal_type%3Alist=ControlTool&portal_type%3Alist=DataGridDemoType&portal_type%3Alist=Discussion+Item&portal_type%3Alist=Document&portal_type%3Alist=DynamicPage&portal_type%3Alist=EUFolder&portal_type%3Alist=Event&portal_type%3Alist=ExFile&portal_type%3Alist=ExtendedEvent&portal_type%3Alist=ExtendedLink&portal_type%3Alist=ExtendedNews&portal_type%3Alist=FAQ&portal_type%3Alist=FAQTheme&portal_type%3Alist=Favorite&portal_type%3Alist=File&portal_type%3Alist=Folder&portal_type%3Alist=GroupSpace&portal_type%3Alist=Image&portal_type%3Alist=Job&portal_type%3Alist=Large+Plone+Folder&portal_type%3Alist=Link&portal_type%3Alist=Member&portal_type%3Alist=MemberDataContainer&portal_type%3Alist=Message&portal_type%3Alist=News+Item&portal_type%3Alist=Newsletter&portal_type%3Alist=NewsletterBTree&portal_type%3Alist=NewsletterReference&portal_type%3Alist=NewsletterTheme&portal_type%3Alist=NewsletterTopic&portal_type%3Alist=Plone+Site&portal_type%3Alist=PloneArticle&portal_type%3Alist=PloneArticleMultiPage&portal_type%3Alist=PloneContactsView&portal_type%3Alist=PressRelease&portal_type%3Alist=PressReview&portal_type%3Alist=SCAuditorium&portal_type%3Alist=SCAuditoriumItem&portal_type%3Alist=Section&portal_type%3Alist=Subscriber&portal_type%3Alist=TempFolder&portal_type%3Alist=Topic&Creator=&submit=Search

I got your message.  I a little unsure about what you need to know.  I thought you said that you bought this chemical before.  What did you use it for and/or what do you need it for?  If you want more info. on the chemical itself go to your search bar and type in "strychnine hcl powder" and the listed sites will give you all the information that you need.

I don't know medically important examples, but nitrocellulose (gun-cotton) is made from nitric acid and cellulose (like from cotton).  I think the nitro-groups replace the OH groups.  The resulting product is an explosive (it can burn without oxygen because it has the required oxidizing groups in the molecule.\n\nThe sugar substitute sucralose (Splenda) is made from sugar where a lot of groups are replaced with chlorines.

There are many you could choose.  These may not be the most efficient, but I'm just going with initial thoughts here.\n\n1.  Aniline -> benzamide\nDiazotise the aniline and trap out with CO2 to form benzoic acid, then make an amide.  Probably easiest way is to make the acid chloride with (COCl)2 and then treat with NH3.\n\n2. Bromobenzene -> 1-phenylethanol\nForm phenylmagnesium bromide by treating bromobenzene with magnesium in diethyl ether, and react with ethanal.\n\n3. Butanal -> 1-chloropropane\nMany ways to do this, none of them nice.\n\nReduce butanal to butanol, de-hydrate, perform a reductive oxonolysis to give 1-propanol and then do a chloro-dehydroxylation with SOCl2 or something like that.\n\nAlterantively you could oxidise and do a Barton-Crich de-carboxylation and trap out the radical with NCS, although this method may not be too successful.\n\nHope these quick ideas help.

do not use that!   use paintball marker oil at a paintball gun store...dicks sporting goods should have it

Bullets are usually made of lead, with an outer shell of copper. Lead is a known carcinogen. It is not a good idea to mess with it, without the required permits and protection. I don't think it is worth the hassle.

You need to specify what kind of propellent: eg, smokeless powder, solid rocket fuel, spray paint propellent, etc.

the powder is the solute and the water added is the solvent.

extract it with an appropriate solvent. it could be water, alcohol, or maybe hexane. this depends on the solubility of the substance your after. then you could freeze dry it to remove the solvent and all your left is the powder form.

It would depend on what the nature is of the unwanted impurities. One could use chemical separation or distillation.  Distillation would be the easiest.

Ah ha.  Thermite.  Magnesium ribbon would be the usual method to start this reaction.\n\nBe careful with this reaction...
