恒沸点,解释恒沸液,塔顶塔底是什么,怎么判断
乙醛不能和水恒沸的````沸点差都80度了...不过乙醛可以与丁烷,乙醚,氯乙烯,1、3丁二烯共沸 恩~~但是乙醛和水真的不能共沸的,之前蒸馏过几次含乙醛的水溶液,20~100度间没有什么特殊沸点的物质 今天又回学校图书馆看了一眼还是没有查到与水的共沸的信息查到了下面两个乙醛共沸物的信息Butane  温度-7.00  含量84.00%Ethyl ether  温度20.50 含量24.00%  另外查到了水与这么多东西的共沸信息Acetic_acid Acetonitrile  Acrolein  Allyl_alcohol Allyl_chloride Benzyl_alcohol 2-Butanol  tert.Butanol Butyl-2-ethoxyethanol  Butyric_acid  Chloral  1-Chloro-2-propanol  Chlorobenzene  Cyclohexanol  Cyclohexylamine  Cyclopentanol  Diacetone_alcohol  Dibutyl_formal  1,2-Dichloroethane Diethyl_ethanolamine Diethylaminoethyl_amine  Diethylaminoethyl_amine  Diethylisopropanol_amine  Diisopropyl_amine  Dimethyl_acetal  2,6-Dimethyl_morpholine  1,3-Dimethylbutyl_amine  1,4-Dioxane  1,3-Dioxolane  Ethanol  1-Ethoxy-2-propanol  2-Ethoxy_ethanol Ethyl_ether  Ethyl_morpholine Ethylene_chlorohydrin  Ethylene_diamine Formic_acid Glycol_diacetate  Hexyl_amine  Hydrogen_bromide Hydrogen_chloride  Hydrogen_fluoride  Hydrogen_iodide  Hydrogen_nitrate  Isoamyl_alcohol  Isopropyl_alcohol Isoveralaldehyde 1-Methoxy-2-propanol 2-Methoxy_ethanol  4-Methyl-2-pentanone  2-Methyl-2-propanol ethyl_acetate  n-Methyl_morpholine Methylal  n-Methylbutyl_amine Methylethyl_ketone Methylvinyl_ketone gamma-Picoline  Propanol  Propionaldehyde Propionic_acid  Propyl_acetate  Propylene_chlorohydrin Pyridine  Triethyl_amine而就是没有乙醛的```相信应该是真的没有吧`...余下全文>>
