环臭氧是一种假设的同素异形体,其与臭氧分子一样有三颗氧原子,但并非角型而是成环状。

简介

[编辑]

直到目前,不同的理论研究已确定环臭氧存在的可能。[2][3][4]另外也有实验指在1450℃以上在氧化镁表面重构中识别出微量环臭氧。[5]目前它并未能大量制造,而其中一个不成功的尝试是借助激光[6]另一个被提出的可能办法是在一个加以限制的空间内使其稳定,例如富勒烯[3]

科学家对其特性有一些预测,如其标准摩尔生成焓比臭氧高130 kJ mol−1,而它生成臭氧的活化能为95 kJ mol−1[7]另外又有建议指,若果环臭氧能大量制造,且它较为稳定,便可加入液态氧中以增加火箭燃料的比冲量[6]
