乙二醇
乙二醇用途
【用途一】
主要用作生产合成树脂、表面活性剂及炸药，也用作防冻剂
【用途二】
用作分析试剂、色谱分析试剂及电容介质
【用途三】
主要用于生产聚酯树脂、醇酸树脂、增塑剂、防冻剂，也用于化妆品和炸药
【用途四】
乙二醇是杀菌剂戊环唑和恶霉灵的中间体。
【用途五】
乙二醇主要用于配制汽车冷却系统的抗冻剂及生产聚对苯二甲酸乙二酯（聚酯纤维和聚酯塑料的原料），也可用于生产其分合成树脂、溶剂、润滑剂、表面活性剂、软化剂、增湿剂、炸药等。乙二醇常可代替甘油使用，在制革和制药工业中分别用作水合剂和溶剂。乙二醇的溶解能力很强，但它容易代谢氧化生成有毒的草酸，因而不能广泛用作溶剂。将乙二醇添加到液压流体中，可防止油基液压流体对系统中橡胶的侵蚀；以乙二醇为主要组分的水基液压流体是一种不能燃烧的液压流体，运用于飞机、汽车和高温作业的模压机。乙二醇有许多重要的衍生物。低分子量聚乙二醇（一缩乙二醇、二缩乙二醇、三缩乙二醇或分别称二甘醇、三甘醇、四甘醇）实际上是环氧乙烷水合制得乙二醇的副产物。二甘醇可用作增湿剂、增塑剂、上浆剂、印刷油墨溶剂、天然气脱水干燥剂和芳烃萃取溶剂。二甘醇二硝酸酯与乙二醇二硝酸酯相似，也是一种重要的工业炸药。高分子量聚乙二醇根据分子量的不同，从无色透明粘稠液体到蜡状固体，也是一类有用的衍生物。用作润滑剂、水分保持剂、溶剂以及橡胶和食品工业的中间体，亦用于配制化妆品以及纺织、造纸等领域的助剂。乙二醇的酯品种很多，广泛用作溶剂。长链脂肪酸的乙二醇酯具有表面改进性能，可单独使用或与其了表面活性剂共用，作为乳化剂、稳定剂、分散剂、增湿剂、发泡剂和悬浮剂等。乙二醇与尿素反应生成环亚乙基脲，用于纺织工业。乙二醇二钠与1，2-二溴乙烷反应，生成二氧六环，这是一种特殊的溶剂。对乙二醇采用不同的氧化剂或反应条件。氧化后可得到乙醇醛、乙二醛、乙醇酸、草酸等。
【用途六】
气相色谱固定液(最高使用温度50℃，溶剂为氯仿)，分离分析低沸点含氧化合物、胺类化合物、氮或氧杂环化合物。测定水泥中的氧化钙, 溶剂, 抗冻剂, 制造聚酯树脂、增塑剂、化妆品、炸药、耐寒润滑油、表面活性剂、清漆、染料、油墨等, 有机合成。

乙二醇合成路线

乙二醇制备
1. 氯乙醇法
以氯乙醇为原料在碱性介质中水解而得，该反应在 100 ℃ 下进行，先生成环氧乙烷，而后在1.01 MPa压力下加压水解生成乙二醇。
2. 环氧乙烷水合法
环氧乙烷水合法有直接水合法和催化水合法，水合过程在常压下进行也可在加压下进行。常压水合法一般采用少量无机酸为催化剂，在50～ 70 ℃ 进行反应。
直接水合法：
催化水合法：
加压水合法 环氧乙烷与水的摩尔比要较高，在1∶6以上，以减少生成醚的副反应，该反应的温度在 150 ℃ ，压力147kPa.水合得到乙二醇。
3.目前有气相催化水合法，以氧化银为催化剂，氧化铝为载体，在150～ 240 ℃ 反应，生成乙二醇。
4.乙烯直接水合法 乙烯在催化剂(如氧化锑TeO2，钯催化剂)存在下在乙酸溶液中氧化生成单乙酸酯或二乙酸酯，进一步水解均得乙二醇。
5.环氧乙烷与水在硫酸催化剂作用下进行水合反应，反应液经碱中和、蒸发、精馏即得成品。或者环氧乙烷和水在一定温度和压力下制得乙二醇，同时副产二乙二醇、三乙二醇和多乙二醇。反应液经蒸发浓缩、脱水、精制得合格产品和副产品。
6.甲醛法 其反应式如下：
7.以工业品乙二醇为原料，经减压蒸馏，于1333Pa下，收集中间馏分即可。
8.将乙二醇真空蒸馏，所得主要馏分用无水硫酸钠进行较长时间干燥，然后用一支好的分馏柱重新真空蒸馏。
