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>>
