-troglycerin –
Materials Required:
-nitric acid
-ice (made possible by the freezer)
-sulfuric acid (already invented)
-thermometer (already invented)
-sodium bicarbonate (already invented)
Procedure:
1-Cool 13 mL of nitric acid using the ice created by the refrigerator.
2-After it has cooled, add to 39mL sulfuric acid (99% h2so4), mixing very slowly.
4-Cool the new mixture to 10-15°C, which we can measure with the thermometer already “invented.”
5-Slowly add enough glycerin to cover the entire surface of the acid.
6-Keep the solution below 30°C.
7-Stir gently for ten minutes, then the nitroglycerin will form as a layer on top of the acid solution, while the sulfuric acid will absorb the excess water.
8-Filter out the nitroglycerin and place it in sodium bicarbonate, which will neutralize much of the acid remaining. This will help to stabilize it.
10-Now slowly and carefully remove the nitroglycerin from the bicarbonate. The usual test to see if nitration has been successful is to place one drop of the nitroglycerin on metal and ignite it. If it is true nitroglycerin it will burn with a clear blue flame.
The chemical reaction going on here is:
C3H5(OH)3 + 3HNO3 + H2SO4 = C3H5(NO3)3 + 3H20 + H2SO4
