六硝基六氮杂异伍兹烷的吸湿性

摘要

The hygroscopicity of CL-20 in four polymorphs at 28 ℃ and a relative humidity of 90% has been tested. α-CL-20 has the highest hygroscopicity being 0.5% in five days,whereas the hygroscopicity of β,γ and ε-CL-20 is all no more than 0.025%.%测定了六硝基六氮杂异伍兹烷(CL-20)四种晶型产品在28 ℃，RH 90％条件下的吸湿性。结果表明，α-CL-20的吸湿率最大,五天内达到0.5％，并随时间的延长吸湿不断增加。β,γ和ε三种晶型的吸湿率均不超过0.025％。
