常用有機(jī)溶劑共沸點(diǎn)

乙瞇的性質(zhì)1.乙讎為無色、透明、易流動(dòng)的液體，揮發(fā)性極大，它的蒸氣有芳香味，但有麻醉性。沸點(diǎn)34.6°C、凝固點(diǎn)一116￡,所以能耐劇冷而不凝凍。比重很輕，在15°C時(shí)為0.720。微溶于水，能溶于乙醇、苯、氯仿等有機(jī)溶劑中。常用有機(jī)溶劑共沸點(diǎn)溶劑沸點(diǎn)/°c共沸點(diǎn)/°c 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 ，80.469.2 8.8異丁醇108.489.988.2丙稀睛78.070.013.0二甲苯137-40.5 92.037.5二氯乙烷83.772.019.5正丁醇117.792.237.5乙睛82.076.016.0毗噪115.594.042乙醇78.378.14.4異戊醇131.095.149.6乙酸乙酯77.170.48.0正戊醇138.395.444.7異丙醇82.480.412.1氯乙醇129.097.859.0乙醯3534 1.0二硫化碳46442.0甲酸101107 26溶劑 1mp b|p D420nD20Aceticacid乙酸17 1181.0491.37166.1512.91.68Acetone丙酮-95 560.7881.358720.716.22.85Acetonitrile乙月青-44 820.7821.344137.511.13.45Anisole苯甲St-3 1540.9941.51704.33331.38Benzene苯 5800.8791.50112.2726.20.00Bromobenzene浪苯-311561.4951.55805.1733.71.55Carbondisulfide二硫化碳-112461.2741.62952.621.30.00
