Hydrolysis of the energetic materials present in a composite modified double base solid rocket propellant
Source abstract
Abstract
Abstract The aqueous hydrolysis of the nitroglycerin (NG), nitrocellulose (NC), and HMX present in CYH, a composite modified double base solid propellant, was successfully performed using either sodium hydroxide (NaOH) or ammonia (NH3) as hydrolyzing agents. The rate of hydrolysis was faster for NaOH compared to NH3. For both hydrolysis agents the rate of hydrolysis of NG was the fastest, followed by NC and then HMX. It was determined that 4 parts of NaOH were required to hydrolyze the energetic ingredients in 10 parts of CYH. A similar determination was not made for NH3. The original set of experiments were done on a small scale (0.030-10 grams of propellant) with laboratory glassware. Later experiments involved the hydrolysis of larger amounts of propellant (200 grams), again using laboratory glassware. The last set of experiments were accomplished with a small scale glass reactor (4 liters) with up to 900 grams of propellant per run. In addition, exhaustive chemical analysis yielded useful information about the hydrolysis products. The combined data was used to design a reactor for the hydrolysis of 4,000 Ibs of CYH propellant.
