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.
