合成

環氧環己烷可由環己烯環氧化反應得到。反應體系可以與過氧酸進行均相反應得到[2],也可以利用催化劑(如銀與氧氣反應)進行非均相反應得到[3][4][5]

 

工業生產環氧環己烷更傾向於採用非均相催化反應,因為這樣有更好的原子經濟性,而且產物容易分類,催化劑可回收重複利用。採用的過氧酸常為過氧化氫[6]。近年來也發現了採用固定化的金屬卟啉絡合物催化氧化有很高的效率[7][8]

在實驗中,常用環己烯與單過氧鄰苯二甲酸鎂英語Magnesium monoperoxyphthalate(MMPP)的水-異丙醇溶液室溫下反應得到環氧環己烷,且反應產率可達到85%[9]

 

性質和反應

環氧環己烷的晶體結構已通過分析方法得到廣泛研究。環氧環己烷可在溶液中經固體酸催化劑的催化下聚合形成聚環氧環己烷[10]
