  • 方法一:工业上,可从丙烯硫酸水合制异丙醇的副产品中回收。丙烯与硫酸反应生成异丙基氢硫酸酯,然后水解为异丙醇。反应过程中,异丙基氢硫酸酯与丙烯继续反应亦生成二异丙基硫酸酯,后者与异丙醇反应生成异丙基氢硫酸酯和二异丙醚。当硫酸水合反应后的物料在解吸塔用蒸汽汽提,使异丙醇与二异丙醚从酸液中释出
  • 用途三:二异丙醚是动物、植物及矿物性油脂的良好溶剂,可用于从烟草中抽提尼古丁;也是石蜡及树脂的良好溶剂,工业上常将二异丙醚和其他溶剂混合应用于石蜡基油品的脱蜡工艺。作为溶剂也应用于制药、无烟火药、涂料及油漆清洗等方面,二异丙醚具有高辛烷值及抗冻性能,可用为汽油掺合剂。本品易形成过氧化物,在振摇时产生爆炸,常加入对苄基氨基苯酚作稳定剂。二异丙醚的麻醉作用较乙醚轻,但麻醉的持续时间长。
  • 灭火剂:干粉, 泡沫, 二氧化碳, 1211, 砂土
  • 具有醚类的特殊气味。能与乙醇和乙醚等大多数有机溶剂混溶,微溶于水,水中溶解度:9 g/L (20°C)。能与水、异丙醇、丙酮、乙腈和乙醇组成共沸物。表面张力32mN/m(23℃)。有刺激性。
