Embodiment 1

[0021] (1) Synthesis of 1,5-Dinitroaminotetrazole Potassium Salt

[0022] At room temperature, sequentially add 0.17g (0.89mmol) 1,5-dinitroaminotetrazole and 3.0mL methanol into the reaction flask, cool in an ice-water bath to 0-5°C, add dropwise 3.0mL containing 0.112g (2mmol) hydrogen The methanol solution of potassium oxide was continued to react at 0-5°C for 0.5 h, filtered, washed with methanol, and dried in vacuum to obtain 0.19 g of white solid with a yield of 79.8%.

[0023] Structure Identification:

[0024] Infrared Spectrum: IR(KBr,cm -1 ), υ: 1510, 1439, 1412, 1367, 1291, 1236, 1228, 1099, 1034, 912, 856

[0025] NMR spectrum: 13 C NMR (DMSO-d 6 ,125MHz), δ: 154.42

[0026] Elemental analysis: Molecular formula CK 2 N 8 o 4

[0027] Theoretical value: C 4.51, N 42.08

[0028] Found: C 4.62, N 42.03.

[0029] The above structural identification data confirmed that the obtained substance was indeed 1,5-dinitroaminotetrazole potassium salt.

Abstract

The invention discloses a di(1,5-nitramine tetrazole)-potassium cupride tetrahydrate compound which has a structural formula (I) as shown in the description. The compound is mainly applied to the field of initiating explosives.

Description

technical field [0001] The invention relates to an energetic material, in particular to a bis(1,5-nitroaminotetrazole)-potassium cuprate tetrahydrate compound. Background technique [0002] The primary explosive is the most sensitive chemical energy, with the characteristics of high sensitivity, high promptness, and high power. When excited by external small initial impulse energy such as impact, friction, acupuncture, flame, etc., it will produce detonation and trigger The secondary charge exploded. At present, lead azide and lead styphate are widely used in the military and civilian fields as the primary explosives. Because these two primary explosives contain the toxic heavy metal element-lead, the use of this type of primary explosives will cause serious pollution to personnel and the environment. With the improvement of people's requirements for the safety of weapons and ammunition and the quality of the environment, the performance defects of lead azide and lead styph...
