性质描述: 无色液体。熔点-5.5℃,沸点194℃(100.5kPa),89℃(3.33kPa),相对密度0.9737(20/4℃),折光率1.4421。能与水、乙醇、乙醚混溶。久置逐渐变黄。
生产方法: 由2,5-二甲基呋喃水解而得。另一个合成方法是乙酰乙酸乙酯钠与纯碘反应生成二乙酰琥珀酸二乙酯,再将其与10%氢氧化钠溶液进行水解。用无水碳酸钾使反应液饱和,析出丙酮基丙酮。用乙醚提取,从提取液蒸去乙醚后,蒸馏剩余物,收集192-194℃馏分得无色产品。国外市售的纯度97%商品,溶点-6-5℃,沸点191℃,相对密度0.973,闪点78℃。
用途: 用作合成树脂、硝基喷漆、着色剂、印刷油墨等的高沸点溶剂,皮革鞣制剂,橡胶硫化促进剂以及杀虫剂、药物原料。

应用
2,5-Hexanedione is used as a reagent in the preparation of trans-2,5-dimethylpyrrolidine. It is also used in the synthesis of 2,5-dimethylpyrroles. Further, it plays an important role as a reagent used for the protection of amino groups in amino sugars and nucleosides. In addition to this, it is used in the preparation of five-membered heterocycles like indane-type and benzannulated systems. It is also employed as a precursor in Diels-alder cycloaddition reactions.

备注
Incompatible with strong oxidizing agents, strong bases, metals and strong reducing agents.
