The synthesis of eight compounds ( borneol ester and isoborneol ester) and other esters catalyzed by nanometer solid superacids were also researched. In addition, we still analyzed the distinction of esterification yield of borneol ester and isoborneol ester. The particle size, surface area, changes of profile and acidity of nanometer solid superacids were mensurated and analyzed by TEM, BET, XRD, IR and acid indicator.

Results show that, following the leaching time extending, the leaching concentrations of heavy metals and lixiviate toxicity of heavy metals increase in the fly ash. When the ratio of liquid and solid add, the leaching concentrations of heavy metals obviously become big, and the Cd's leaching concentration is the biggest, when the ratio of liquid and solid is 90, the Cd's leaching ratio exceed the percent of 70. At the time pH is about 7, the leaching concentrations of heavy metals are the lowest. When the grain size is the bigger or little, the leaching concentrations of heavy metals are lower, however when the grain size is 250-900 μm, the concentrations are higher. After fly ash melt in the high temperature, the lixiviate toxicity of heavy metals greatly reduce, which explains that the effect of melting on heavy metals' stabilization is very good.

Since there exists some disadvantages such as poor mechanic properties and much higher burning rate pressure exponents (?1) in the fundamental formulations, this work is devoted to the improvements of combustion characteristics and mechanic properties of LOVA propellants. The effects of the crystal shape, size and contents of nitroamine particles, the types of binder, plasticizer and surface-active agents and the contents of NC on combustion performance are studied by closed bomb tests. In the mechanic properties tests, the effects of the types of binders, plasticizers and solid fillers, the interaction between binders and solid fillers and technological procedures on propellant mechanic properties are researched.
