Embodiment 11

[0023] The preparation of embodiment 11,8-dihydroxyanthraquinone lead compound

[0024] (1) Weigh 4.8g (0.02mol) of 1,8-dihydroxyanthraquinone, disperse it in 200mL deionized water, fully dissolve it with 1.6g (0.04mol) sodium hydroxide to form a clear solution, and adjust the pH value of the solution to 9 ; Weigh 6.62g (0.02mol) of lead nitrate and dissolve it in 50mL of deionized water to form a solution, add it to the 1,8-dihydroxyanthraquinone solution, stir and mix evenly;

[0025] (2) Stir and react at a constant temperature of 70°C for 2 hours, then cool and stand still;

[0026] (3) The precipitate was washed with deionized water several times, filtered and dried to obtain 8.7 g of red 1,8-dihydroxyanthraquinone lead compound with a yield of 97.8%.

Embodiment 41

[0044] Embodiment 41, application of 8-dihydroxyanthraquinone lead compound

[0045] The structure of dihydroxyanthraquinone contains two hydroxyl groups and two carbonyl groups. One molecule of anthraquinone precursor can react with one molecule of lead. The resulting new combustion catalyst can effectively adjust the combustion performance of double-base / modified double-base propellants. . The catalytic performance of the double-base / modified double-base propellant was tested below by adding 1,8-dihydroxyanthraquinone lead compound to the double-base / modified double-base propellant.

Abstract

The invention discloses a 1,8-dihydroxy anthraquinone lead compound which is shown as the structural formula (I). The 1,8-dihydroxy anthraquinone lead compound can be used as a combustion catalyst, has a good catalytic effect on a biradical solid propellant or a modified biradical solid propellant, and can significantly increase the burning rate of the biradical solid propellant or the modified biradical solid propellant and reduce the pressure index.

Description

technical field [0001] The invention relates to a 1,8-dihydroxyanthraquinone lead compound, which can be used as a combustion catalyst for solid propellants. technical background [0002] In terms of improving the combustion performance of double-base propellants or modified double-base propellant formulations, the current common method is to add some compounds as combustion catalysts. Compounds can not only increase the propellant burning rate and reduce the pressure index, but also produce "platform combustion " or " Maisa combustion " and other combustion characteristics to adjust the combustion performance of solid propellants. Therefore, the combustion catalyst is an indispensable component in the formulation of the double-base solid propellant, and plays a key role in regulating the combustion performance of the propellant. At present, most double-base propellants use the method of adding a certain amount of composite catalysts composed of lead, copper, and carbon bla...
