摘　　要：五氧化二氮作为一种绿色硝化剂,容易分解为四氧化二氮和氧气。其中四氧化二氮对硝化反应有负面影响,降低其在硝化体系中的含量有着极其重要的意义。在不同温度下,选用不用溶剂的五氧化二氮溶液,在不同流速下通入臭氧气体,控制五氧化二氮中四氧化二氮的含量<1%,五氧化二氮纯度最高可达98.1%,达到纯化五氧化二氮的目的。As a green nitrating agent,dinitrogen pentoxide tends to decompose and form dinitrogen tetroxide and oxygen. Since dinitrogen tetroxide has negative effect on nitrating reaction,reducing its content in nitrating system is of great significance. The purification of dinitrogen pentoxide was investigated at different temperature with different kinds of dinitrogen pentoxide solution. The influence of ozone flow rates on the purification process was investigated. Dinitrogen tetroxide in dinitrogen pentoxide was reduced to less than 1% and the highest purity of dinitrogen pentoxide was up to 98. 1%.
