TACOT was synthesized by the improved technics, the time of reaction was shortened to a half, and the operation was predigested. Moreover, the total yields have been increased from 26.7% to 52.0%. This methods reduced the cost of TACOT greatly.%采用经改进的四硝基二苯并-1，3a,4,6a-四氮杂戊搭烯(代号为TACOT)的合成工艺，将TACOT的合成总时间缩短了一半，简化了合成操作，将产物的总得率由26.7%提高至52.0%，从而大大降低了TACOT的成本。Q
