Molecular formula : C3H5N3O9
MW : 227.09
CAS No. 55-59-63-0
nature : pale yellow viscous liquid. The temperature 2-3 ° C (unstable). 13 ° C (stable). 50-60 ° C begin to decompose. The relative density of 1.5918 (25 / 4 ° C). Soluble ethanol, ethyl ether, acetone, acetic acid, benzene, nitrobenzene, the water-soluble. Case of concentrated sulfuric acid, sodium hydroxide and sodium sulfide solution break down. The explosion temperature of 260 ° C. Slightly volatile, almost odorless, channeling permeability flavored.
Preparation Methods : fuming nitric acid and concentrated sulfuric acid at 40 ° C by adding the following pot mixed reaction, cooling to 30 ° C, 71/92 glycerol. Increase mixer 30 minutes to complete. Drawing into the separator, Stillness stratification and emit lower sulfate, the upper nitroglycerine first washing and reuse of 8% and 2% sodium borate solution to adjust the pH to 7-8, and then washed two times rested overnight, delamination. Reservoir namely pure nitroglycerin. The yield of 93%. The materials for high explosives. For medicinal products using ethanol diluted to below 10%.
purposes : mainly used for explosives, usually mixed with other explosives; Cellulose nitrate is also a good gelling agent. Medicine for vasodilator, with the relaxation of vascular smooth muscle relaxation and the role for angina and Cholecystagia prevention and treatment.
