'''缩水甘油'''，分子式C<sub>3</sub>H<sub>6</sub>O<sub>2</sub>。

==性质==
无色几乎无臭液体。与水、低碳[[醇]]、[[乙醚]]、[[氯仿]]、[[苯]]、[[甲苯]]混溶，部分溶于[[四氯乙烯]]、[[二甲苯]]、[[1,1,1-三氯乙烷]]，几乎不溶于[[脂肪烃]]和[[脂环烃]]。可通过皮肤吸收进入人体，可腐蚀皮肤、呼吸系统、眼部和胃肠道粘膜。

==制备==
以[[过氧化氢]]为氧化剂，催化（如NaHWO<sub>4</sub>）、温度40～45°C、pH＝4～5下对[[烯丙醇]]进行[[环氧化]]，得到缩水甘油。分离出副产[[丙烯醛]]和多余原料烯丙醇，经真空蒸馏，制得缩水甘油成品。

==用途==
用作纤维和塑料改性剂、[[环氧树脂]]稀释剂、杀菌剂、卤代烃稳定剂、食品保藏剂、芳烃萃取剂和制冷系统干燥剂等。
