1-氨基乙醇2-氨基乙醇CAS: 141-43-5 分子式: C2H7NO 分子量: 61.08 沸点: 170℃ 熔点: 10-12℃ 中文名称: 乙醇胺;2-氨基乙醇;2-羟基乙胺;一乙醇胺;单乙醇胺;氨基乙醇;1-氨基乙醇2-氨基乙醇;乙醛合氨乙醇胺 英文名称: 2-Aminoethanol;Ethanolamine;2-Hydroxyethylamine;2-amino-Ethanol;1-amino-2-hydroxyethane;2-amino-1-ethanol;2-aminoaethanol;2-aminoetanolo;2-hydroxyethanamine;aethanolamin 性质描述: 氨分子中的氢被羟乙基--CH2CH2OH取代而生成的一类化合物,可分为一乙醇胺;二乙醇胺和三乙醇胺。通常一乙醇胺简称乙醇胺。一;二;三乙醇胺在室温下均为无色透明的粘稠液体;有吸湿性和氨臭;能与水;乙醇和丙酮等混溶,微溶于乙醚和四氯化碳;能吸收二氧化碳和硫化氢;与无机酸和有机酸反应生成酯;均具碱性。乙醇胺的主要物理常数如下:熔点10.5℃,沸点170℃,58℃(0.67kPa),相对密度1.0180(20、4℃),动力粘度(20℃)24.14mPa·s,折射率1.4540,闪点93.3℃。25℃时,在苯中的溶解度为1.4%,在乙醇中的溶解度为2.1%,在四氯化碳中的溶解度为0.2%。有强的乳化作用和起泡作用。 生产方法: 乙醇胺常存在于磷脂中,并常与胆碱共存,因此也称为胆胺。在血清蛋白腐烂发酵液中也发现有乙醇胺。工业上乙醇胺可由氨与环氧乙烷反应制得。将环氧乙烷;氨水送入反应器中,在反应温度30-40℃,反应压力70.9-304kPa下,进行缩合反应生成一;二;三乙醇胺混合液,在90-120℃下经脱水浓缩后,送入三个减压精馏塔进行减压蒸馏,按不同沸点截取馏分,则可得纯度达99%的一乙醇胺;二乙醇胺和三乙醇胺成品。在反应过程中,如加大环氧乙烷比例,则二;三乙醇胺生成比例增大,可提高二;三乙醇胺的收率。 用途: 一乙醇胺主要用作合成树脂和橡胶的增塑剂;硫化剂;促进剂和发泡剂;以及农药;医药和染料的中间体。也是合成洗涤剂;化妆品的乳化剂等的原料。纺织工业作为印染增白剂;抗静电剂;防蛀剂;清净剂。也可用作二氧化碳吸收剂;油墨助剂;石油添加剂。一乙醇胺广泛用作从各种气体(如天然气)中提取酸性组分的净化液。由一乙醇胺盐酸盐环合;中和可制得六水合哌嗪。一乙醇胺盐酸盐经氯化亚砜氯代,再被硫代硫酸钠取代,可制得β-氨基乙基硫代硫酸盐。这是一种染料中间体,用于生产缩聚翠蓝13G。一乙醇胺与二硫化碳反应可制得在橡胶和制药工业中有应用的中间体硫基噻唑啉。
