CL-20制备及晶体研究进展

As a typical representative of the third generation energetic materials, 2, 4, 6, 8, 10, 12-hexanitro-2, 4, 6, 8, 10, 12-hexaazaisowurtzitane (CL-20) is currently the most powerful energetic compound that has already been commercially available. The important research directions are, at present, the optimum synthesis of CL-20 and the preparation of CL-20-based high energy and low sensitivity energetic compounds in the development of energetic materials. The development status of the intermediates in the preparation of CL-20 was analyzed and summarized. The solutions and prospects of the intermediates were also proposed. In addition, the research progress, structural characteristics and main properties of CL-20 crystal products were also discussed. Through sorting out the synthesis and crystals of CL-20, it is concluded that low-cost, high yield, high purity and environmental friendliness are the future development direction of the synthesis process of CL-20.
