一般說明

1,3-二恶烷是一种杂环乙缩醛,常用作制剂和生产工艺中的绿色溶剂。它还可用作有机合成中的反应物。1,3-二恶烷的长期储存会形成有机过氧化物。可通过添加丁基羟基甲苯(BHT)作为稳定剂而抑制这一过程。BHT能去除形成过氧化物所需的自由基。

應用

1,3-二恶烷可用作以下反应的溶剂:      
  • 从生物质中提取可生物降解的聚(3-羟基丁酸)(PHB)。     
  • 生产稳定的多壁碳纳米管(MWCNT)分散液用于合成修饰玻璃碳电极。
  • 在maghnite-H+ 催化剂存在的情况下通过1;3;5-三恶烷的阳离子共聚反应合成共聚物(聚氧亚甲基)。

它也可作为反应物用于通过Sc(OTf)3催化的开环聚合反应制备准固态聚1,3-二恶烷电极。
