Embodiment 1
[0029] (1) Take 5.2g 4-nitro-2', 4'-dihydroxybenzophenone is fully dissolved with NaOH solution to form a clear solution, adjust the pH of the solution to be 9; weigh 3.3g Pb(NO 3 ) 2 Dissolve it with deionized water to form a solution, add it to the 4-nitro-2',4'-dihydroxybenzophenone solution, stir and mix evenly;
[0030] (2) Stir and react at a constant temperature of 70°C for 1 hour, then cool and stand;
[0031] (3) The precipitate was washed with deionized water several times, filtered, and dried to obtain 4-nitro-2', 4'-dihydroxybenzophenone lead (II) complex, and the product yield was 80.2%.
[0032] The C and H contents of 4-nitro-2',4'-dihydroxybenzophenone lead (II) complex were analyzed by elemental analyzer, and Pb was determined by EDTA volumetric method. Pb(C 13 h 8 o 5 N) 2 ·H 2 Theoretical calculation of elemental analysis of O: C41.84, H 2.17, N 3.78, Pb 27.94; experimental determination: C 41.22, H 2.26, N 3.61, Pb 28.37, thus the simplified chemical...
Embodiment 2
[0035] (1) Take 5.2g 4-nitro-2', 4'-dihydroxybenzophenone is fully dissolved with NaOH solution to form a clear solution, adjust the pH value of the solution to 9.2; weigh 1.8g Cu(NO 3 ) 2 ·3H 2 O is dissolved in deionized water, added to 4-nitro-2', 4'-dihydroxybenzophenone solution, stirred and mixed evenly;
[0036] (2) Stir and react at 90°C for 1.5 hours, then cool and let stand;
[0037] (3) The precipitate was washed with deionized water several times, filtered, and dried to obtain 4-nitro-2',4'-dihydroxybenzophenone copper (II) complex, and the product yield was 62.3%.
[0038] The C and H contents of 4-nitro-2',4'-dihydroxybenzophenone copper (II) complex were analyzed by elemental analyzer, and Cu was determined by EDTA volumetric method. Cu(C 13 h 8 o 5 N) 2 ·H 2 Theoretical calculation of elemental analysis of O: C51.89, H 2.70, N4.69, Cu 10.63; experimental determination: C 51.28, H 2.58, N 4.52, Cu 10.95, thus the simplified chemical formula of the complex ...
Embodiment 3
[0042] 4-nitro-2', the basic formulation of the double base propellant used in the catalytic performance experiment of the energetic complex of 4'-dihydroxybenzophenone is: nitrocellulose (NC, 12.0%N) 59%, Nitroglycerin (NG), 30%, diethyl phthalate (DEP) 8.5%, other additives 2.5%. The drug material is dosed by 500g, and the combustion catalyst 4-nitro-2', 4'-dihydroxybenzophenone lead (II) complex is an additional amount, and the addition amount is 2.5%; the blank propellant sample of the control group does not contain combustion catalyst.
[0043] The propellant sample is prepared by the conventional solvent-free compression molding process of absorption-water displacement-release-cooking-calendering-cutting into drug strips. The burning rate of the sample was measured by the target line method. The side of the treated Ф5×150mm grain column was dipped and coated with polyvinyl alcohol solution for 6 times and dried in the air, and then the burning rate test was carried out...
