Property and Preparation of Glycol Dinitrate

Glycol dinitrate, referred as to EGDN or GDN, is also called as nitrated glycol. It is a transparent liquid and an important liquid explosive [67]. 

Glycol dinitrate is nonhygroscopic. Its solubiUty in water is small and increased with temperature elevation. The solubihty of glycol dinitrate in 100 mL water is Usted in Table 5.11. 

The viscosity of glycol dinitrate is 0.08056 poise at 15 °C and 0.02831 poise at 40 °C, about 10 times smaller than nitroglycerine. 

The refractive index of glycol dinitrate is slightly increased with temperatures, as shown in Table 5.13. 

Glycol dinitrate will be hydrolyzed in the aqueous solution of sodium hydroxide or potassium hydroxide under heating. If glycol dinitrate is added into the ethanol solution of potassium hydroxide, a vigorous reaction would take place to produce potassium nitrite and potassium glycolate.
