Abstract
In order to study the properties of 5,7-diamino-4,6-dinitrobenzenfuroxan(CL-14), CL-14 was refined via recrystalliza-tion of potassium salt of CL-14, acidification at high temperature and acid elimination under heating.The sensitivity and thermal stability of unrefined CL-14 and refined CL-14 were tested by the standardization method GJB772A-1997.The peak temperature of exothermic decomposition reaction of unrefined CL-14 and refined CL-14 was determined by DSC.Results show that the pH of refined CL-14 is 6.5.The impact sensitivity and friction sensitivity are 24%and 16%respectively.The amount of gas evolved of refined CL-14 obtained by Vacuum Stability Test with 200 ℃/48 h is 0.81 mL・ g-1 .The peak temperature of exothermic decom-position reaction of refined CL-14 is 313.7℃, 13.7℃higher than that of the unrefined CL-14, showing that the refined CL-14 has lower acidity and better thermal stability.关键词
