Synthesis of guanidine nitrate
Guanidine nitrate is both an explosive compound and a precursor to other explosives with similar properties. I do not have many specifics relating to explosive or chemical properties of this compound. Some legitimate uses of guanidine nitrate include the manufacturing of trimethoprim, folic acid, sulpha guanidine, organic synthetics, photographic chemicals, and disinfectants.

Place a mixture of 210 g of dicyanodiamide and 440 g of ammonium nitrate in a 1-L Florence flask, the flask is immersed in an oil bath for heating which has a thermometer in the oil. The oil bath should be preheated to 110-120 °C before placing the flask in, then it is warmed to 160 °C over 30 minutes, and held at this temp for 2 hours. At the end of that time the flask is removed and allowed to cool, and the contents are extracted on a steam bath by warming with successive portions of water. About 2 L of water will be needed; the hard cake of crystals will dissolve slowly, so sufficient time must be given for each portion of water to become saturated before it is decanted. The combined solution is filtered while hot for the removal of white insoluble material (that being ammeline and ammelide), concentrated to a volume of about 1 liter, and allowed to crystallize. There may be some crystals of guanidine nitrate mixed with the ammeline and ammelide, these can be re-dissolved in hot water and cooled to precipitate the ammeline and ammelide again, the guanidine nitrate will remain in solution. The mother liquors are concentrated to a volume of about 250 mL for a second crop, after the removal of which the residual liquors are discarded. The crude guanidine nitrate may be recrystallized by dissolving it in the least possible amount of boiling water and allowed to cool, or it may be dried thoroughly and used directly for the preparation of nitroguanidine.
While a good faith effort has been made to ensure the accuracy of all scientific information presented on this page, the possibility exists that some errors have invaded the machine. Furthermore, there may be certain omissions of physical properties, reaction conditions, necessary equipment, storage and handling requirements, and critical safety data. As with any scientific endeavor, especially chemistry, the necessary safety precautions should be observed at all times.
Errors are not allowed to persist in the Chem Lab once they have been discovered, but your help is needed to find them. If you observe an error in any lab, or a critical omission of special safety precautions, and you can provide a published reference to support your claim, please submit your correction via the error reporting form. Additionally, please use the form to provide missing information such as boiling points, densities, etc. If you have written, or have references to, alternate methods of synthesis, or improvements in the synthesis of any chemical in the Chem Lab, please take advantage of the "Submit your Science" page to have your contribution published on the site.
