Embodiment 1

[0031] (1)Cd 0.5 Zn 0.5 Preparation of S

[0032] Na 2 S (1.5608g, 20mmol) was dissolved in 40mL deionized water, and Cd(OAc) was added 2 2H 2 O (2.305g, 10mmol) and Zn(OAc) 2 2H 2 O (1.8348 g, 10 mmol) in 40 mL of an aqueous solution was stirred at room temperature for 24 hours. Then, the product was filtered, washed several times with deionized water, and dried in an oven at 80 °C for 5 h.

[0033] (2) Preparation of NTP

[0034] a: Place triptene (1.25g, 5mmol) in a three-necked flask, add concentrated HNO 3 50 mL, the mixture was heated and stirred at 75° C. for 24 h, and condensed under reflux. The reaction solution was a brown solution, which was cooled to room temperature, then poured into H 2 O (1000 mL) was stirred for 30 min. The precipitate was collected, washed with distilled water, and dried in air. The crude product was purified with dichloromethane / petroleum ether (1:1) as the eluent to give the white solid products 2,6,14-trinitrotriptene (2a) and ...
