Example Embodiment
[0016] Example 1
[0017] (1) In a three-necked flask equipped with a stirrer and an HCl absorption system, add 3.38 g gallic acid, 3.78 g pyrogallic acid, and 5 g anhydrous ZnCl 2 And 6ml POCl 3 , And then add 3ml sulfolane.
[0018] (2) Start stirring to make it evenly mixed, heat to 70°C, and react at constant temperature for 2.5 hours.
[0019] (3) Slowly add water to the reaction flask and stir until all is dissolved, then pour into 300ml of ice water and stir thoroughly. The above solution was allowed to stand still for 30 minutes, filtered under normal pressure, and washed with water to obtain a crude product.
[0020] (4) Heat and dissolve the crude product in 200ml water, add activated carbon treatment, heat filtration, cooling, suction filtration, washing, drying, to prepare 2,3,3',4,4',5'-hexahydroxybenzyl The ketone is a green-yellow needle-like crystal with a melting point of 277.9-278.5°C and a yield of 68.5%. The product uses FTIR spectrum and 1 HNMR spectrum to anal...

[0024] Example 2
[0025] The basic formula of the modified double-base propellant is: 66% of the double-base adhesive, 26% of RDX (RDX), No. 2 medium-sized agent (C 2 ) 2.0%, other additives 6%. The samples were prepared according to the conventional solvent-free stretch forming process of absorption, flooding, ripening, calendering, and cutting into medicine strips. The medicinal material is mixed according to 500g, the catalyst is an external amount, and the added amount is 3.0%; the control blank propellant sample does not contain the catalyst.
[0026] The burning rate is measured by the target line method. The side of the treated Φ5×150mm small grains were immersed and coated with polyvinyl alcohol solution for 6 times and dried, and then the burning rate was tested in a nitrogen-filled slow-moving burning rate meter. The test temperature is 20°C, and the pressure range is 2MPa~22MPa.
