MERCURY FULMINATE 2 - Exodus - Mercury fulminate is perhaps one of the oldest known initiating compounds. It can be detonated by either heat or shock, which would make it of infinite value to a terrorist. Even the action of dropping a crystal of the fulminate causes it to explode. A person making this material would probably use the following procedure: MATERIALS EQUIPMENT
ÄÄÄÄÄÄÄÄÄ ÄÄÄÄÄÄÄÄÄ
5 g mercury glass stirring rod
35 ml concentrated 100 ml beaker (2)
nitric acid
ethyl alcohol (30 ml) adjustable heat source distilled water blue litmus paper funnel and filter paper Solvent alcohol must be at least 95% ethyl alcohol if it is used to make mercury fulminate. Methyl alcohol may prevent mercury fulminate from forming. Mercury thermometers are becoming a rarity, unfortunately. They may be hard to find in most stores as they have been superseded by alcohol and other less toxic fillings. Mercury is also used in mercury switches, which are available at electronics stores. Mercury is a hazardous substance, and should be kept in the thermometer or mercury switch until used. It gives off mercury vapors which will cause brain damage if inhaled. For this reason, it is a good idea not to spill mercury, and to always use it outdoors. Also, do not get it in an open cut; rubber gloves will help prevent this. 1) In one beaker, mix 5 g of mercury with 35 ml of concentrated nitric acid, using the glass rod. 2) Slowly heat the mixture until the mercury is dissolved, which is when the solution turns green and boils. 3) Place 30 ml of ethyl alcohol into the second beaker, and slowly and carefully add all of the contents of the first beaker to it. Red and/or brown fumes should appear. These fumes are toxic and flammable. 4) After thirty to forty minutes, the fumes should turn white, indicating that the reaction is near completion. After ten more minutes, add 30 ml of the distilled water to the solution. 5) Carefully filter out the crystals of mercury fulminate from the liquid solution. Dispose of the solution in a safe place, as it is corrosive and toxic. 6) Wash the crystals several times in distilled water to remove as much excess acid as possible. Test the crystals with the litmus paper until they are neutral. This will be when the litmus paper stays blue when it touches the wet crystals 7) Allow the crystals to dry, and store them in a safe place, far away from any explosive or flammable material. This procedure can also be done by volume, if the available mercury cannot be weighed. Simply use 10 volumes of nitric acid and 10 volumes of ethanol to every one volume of mercury. |
