Study of Relationships Between Fractional Conversion and Reaction Time with Heat of Dilution of Mixed Acid and It’s Effects on Safe Operating Conditions at Continuous Nitroglycerin Manufacture
Nitroglycerin (NG) is a powerful explosive widely used by the military in weapon, ignitions and propellant formulations for a long time. It is produced by the glycerin nitration reaction. The resulting pale yellow, viscous liquid was extremely sensitive to explosive initiation by shock, heat creating an extremely dangerous and unpredictable compound. Many fire and explosion incidents have occurred during its manufacturing process owing to its severe thermal instability in both the nitration reaction and the purification processes. The temperature of the reaction is increased by both the heat of reaction and the heat of dilution of the mixed acid. Sometimes, the heat of dilution exceeds the heat of reaction. The heat of dilution varies with the reaction conditions, which thus affect the rate of reaction. In this investigation, we estimate the relationships between fractional conversion and reaction time with heat of dilution of mixed acid that these reaction parameters are then used to evaluate the safe operating conditions in a continous nitroglycerin manufacture.
