常用有机溶剂共沸点

1、最新资料推荐乙醚的性质1. 乙醚为无色、透明、易流动的液体，挥发性极大，它的蒸气有芳香味，但有麻醉性。沸点34.6、凝固点 116，所以能耐剧冷而不凝冻。比重很轻，在 15时为 0.720。微溶于水，能溶于乙醇、苯、氯仿等有机溶剂中。常用有机溶剂共沸点溶剂沸点 / 共沸点 /含水量 /%氯仿61.256.12.5甲苯110.585.020四氯化碳77.066.04.0正丙醇97.287.728.8苯80.469.28.8异丁醇108.489.988.2丙稀腈78.070.013.0二甲苯137-40.592.037.5二氯乙烷83.772.019.5正丁醇117.792.237.5乙睛82.0
