二乙烯三胺
二乙烯三胺用途
用作制备氨羧络合试剂、气体净化剂和树脂固化剂
【用途二】
用于合成聚酰胺树脂、表面活性剂、润滑剂、环氧树脂固化剂等
【用途三】
主要用作溶剂和有机合成中间体，用于制取气体净化剂（脱CO2用）、润滑油添加剂、乳化剂、照相用化学品、表面活性剂、织物整理剂、纸张增强剂、氨羧络合剂、无灰添加剂、金属螯合剂、重金属湿法冶金及无氰电镀扩散剂、光亮剂、离子交换树脂及聚酰胺树脂等。由二乙三胺与双氰胺反应可制取固色剂苏普拉菲克斯DFC（Suprafix DFC）：将30.9份二乙三胺加入带齿轮搅拌的反应器中，在搅拌下加入24.8份双氰胺。当温度升到100℃时，开始释放出氨，然后将温度缓缓升至145-160℃，物料由液态逐渐变得粘稠。反应5-8小时后，放出反应物，冷却后加以粉碎。由乙二胺、三乙四胺、四乙五胺与双氰胺反应，或者二乙三胺与碳酸胍反应都能得到类似的固色剂。另外，二乙三胺和双氰胺的酯比不同，生成产物的粘稠程度也不同。这类固色剂用于直接染料染色后处理，以改进牢度性能，特别是水洗牢度。用含0.3%固色剂进行处理，棉布水洗牢度可由1级提高至4-5级。二乙三胺为高活性环氧树脂固化剂，主要用于层压制品、浇铸制品、粘合剂和涂料等，一般用量为5-10份，但这类脂肪族多胺具有水溶性，蒸气压较高，对操作人员的皮肤有刺激作用，因此发展了各种改性的品种。
【用途四】
氨羧络合剂，硫磺、酸性气体、染料及各种树脂的溶剂，酸性物质的皂化剂，气体净化剂。树脂固化剂。

二乙烯三胺制备
1.由二氯乙烷氨化法制得。将1,2-二氯乙烷和氨水送入管式反应器中于150-250℃温度和392.3kPa压力下进行热压氨化反应。反应液以碱中和，得到混合游离胺，经浓缩同时除去氯化钠，然后将粗品减压蒸馏，截取195-215℃之间的馏分，即得成品。此法同时联产乙二胺、三亚乙基四胺、四亚乙基五胺和多亚乙基多胺，可通过控制精馏塔温度蒸馏胺类混合液，截取不同馏分进行分离而得。
精制方法：用金属钠或无水硫酸钙脱水后减压蒸馏精制。若混有哌嗪时，可与四丙烯进行共沸分离。
2.氨解 将二氯乙烷与氨水以1∶（4～6）（mol）分别由计量泵输入，物料流经乳化混合器后进入管式反应器。在预热段加热至130℃，压力保持约4MPa，物料在反应器中的总停留时间为2min，由针形阀排出，经导管流入中和锅。
3.中和 向中和锅内加入30%的氢氧化钠溶液（按二氯乙烷投料量计算，过量10%），当氨解反应液连续流入中和锅时，大部分释出的氨由锅顶排出，导入氨吸收罐回收供氨解反应用。每批中和反应完成后，移入浓缩塔釜，用夹套加热，使氨驱尽并蒸出大部分水分，此时塔顶温度为96～100℃；浓缩过程中有氯化钠析出，用脱盐箱分离过滤；当塔顶温度为100～110℃之间时，收集馏出物，其中含有少量乙二胺，可再行浓缩回收；塔顶温度110～118℃间的馏出物系30%～70%的乙二胺粗品，经精馏提浓后为70%的乙二胺产品。浓缩釜残物卸出后滤去氯化钠，滤液分两层。上层油状物为乙烯胺类产品混合物，下层为浓碱液，可回收供中和反应用。
4.分馏 将已分离掉碱液的乙烯胺类混合物移入精馏塔釜中，在常压下分馏，当塔顶温度为115～118℃时，收集获得的乙二胺。然后进行减压分馏，在真空度98.64KPa下，分别收集90～140℃馏分为二乙烯三胺，140～180℃馏分为三乙烯四胺，180～200℃馏分为四乙烯五胺，200℃以上全部馏出物为多乙烯多胺；当二氯乙烷与氨的配比为1∶6（ 摩尔比）时，按上法可得占产量26%的二乙烯三胺。
