二乙醇胺制备方法及用途

制备方法

1.由环氧乙烷与氨反应得到二乙醇胺,同时也得到一乙醇胺和三乙醇胺。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。精制方法:工业制品中含有2%以下的乙醇胺、三乙醇胺和1.5%以下的水分。精制时先进行减压蒸馏,再用水蒸气蒸馏除去乙醇胺。三乙醇胺可在其水溶液中加入氢氧化钠使成碱金属盐析出除去。最后再进行减压蒸馏精制。操作中注意防止吸收二氧化碳。

用途简介

1.主要用作CO2、H2S和SO2等酸性气体吸收剂、非离子表面活性剂、乳化剂、擦光剂、工业气体净化剂、润滑剂。亚氨基二乙醇又称二乙醇胺,是除草剂草甘膦的中间体。用作气体的净化剂,也用作合成药物及有机合成的原料。 2.在洗发剂和轻型去垢剂内用作增稠剂泡沫改进剂,在合成纤维和皮革生产中用作柔软剂。二乙醇胺与70%硫酸作用,脱水环化生成吗啉(即1,4-氧氮杂环己烷)。吗啉和二乙醇胺都是有机合成的中间体,例如可用来生产纺织工业中某些光学漂白剂,吗啉的脂肪酸盐可用作防腐剂,吗啉还可用来生产中枢抑制药福尔可定或作为溶剂。二乙醇胺在分析化学上用作试剂和气相色谱固定液,可选择性地保留和分离醇、二醇、胺、吡啶、喹啉、哌嗪、硫醇、硫醚和水。 3.二乙醇胺是重要的缓蚀剂,可用于锅炉水处理、汽车引擎的冷却剂,钻井和切削油以及其他各类润滑油中起缓蚀作用。还在天然气中用作净化酸性气体的吸收剂。在各种化妆品和药品中用作乳化剂。在纺织工业中作润滑剂,还可作润湿剂和软化剂以及其他的有机合成原料。 4.在胶黏剂中用作酸吸收剂、增塑剂、软化剂、乳化剂等。还用作石油气、天然气及其他气体中酸性气体(如硫化氢、二氧化碳等)的吸收剂。是合成医药、农药、染料中间体及表面活性剂的原料。在酸性条件下用作油类、蜡类的乳化剂,皮革及合成纤维的软化剂。在洗发液和轻型去垢剂中用作增稠剂及泡沫改进剂。还用作洗涤剂、润滑剂、光亮剂及发动机活塞除灰剂等。 5.用作镀银、镀镉、镀铅、镀锌络合剂等。 6.用作分析试剂,酸性气体吸收剂,软化剂和润滑剂,以及用于有机合成。

呼吸系统防护：空气中浓度超标时，建议佩带防毒口罩。
眼睛防护：可采用安全面罩。
防护服：穿工作服(防腐材料制作)。
手防护：戴橡皮手套。
其它：工作现场禁止吸烟、进食和饮水。工作后，淋浴更衣。进行就业前和定期的体检。
三、急救措施
皮肤接触：脱去污染的衣着，立即用流动清水彻底冲洗。
眼睛接触：立即提起眼睑，用流动清水或生理盐水冲洗至少15分钟。或用3%硼酸溶液冲洗。立即就医。
吸入：迅速脱离现场至空气新鲜处。必要时进行人工呼吸。就医。
食入：误服者立即漱口，给饮牛奶或蛋清。就医。
灭火方法：雾状水、二氧化碳、砂土、泡沫、干粉。
