Abstract

The hydrocarbon oil and n-octanol were used to pretreat the waste solvents from 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane (CL-20) recrystallization process, and the white CL-20 solid was recovered. Ethyl acetate and chloroform were distilled by azeotropy for their different boiling points. The components of waste solvents and precipitated solid were characterized by high performance liquid chromatography (HPLC), fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM). Results show that the waste solvents mainly contain chloroform, ethyl acetate and α-CL-20.The purity of α-CL-20 recovered by hydrocarbon oil was 99.1% with the recovery rate up to 79.5%.
