乙二醇二乙酸酯上游产品

乙二醇二乙酸酯下游产品

乙二醇二乙酸酯制备

1. 由1,2-二溴乙烷与乙酸钾反应而得。

2. 由乙二醇和乙酸酐反应制造的。主要杂质是乙二醇一乙酸酯。精制时用氯化钙和无水碳酸钾干燥，然后在减压下蒸馏。

3.制法：

于装有搅拌器、回流冷凝器的反应瓶中，加入冰醋酸30mL，1,2-二溴乙烷（2）93g（0.5mol），新煅烧过的醋酸钾98g（1.0mol），吡啶1.5g，搅拌下加热回流3h。改为蒸馏装置，蒸出可挥发部分直至蒸馏完全。将馏出液中加入冰醋酸2mL，1,2-二溴乙烷（2）93g（0.5mol），新煅烧过的醋酸钾98g（1.0mol），吡啶1.5g，再搅拌下加热回流3h。改为蒸馏装置进行蒸馏，收集如下各种馏分：①140℃以前的馏分；②140～170℃的馏分（30～39g）；③170～190℃的馏分（70～78g）。将140～170℃的馏分重新蒸馏，收集170～190℃的（10～16g）。将170～190℃的馏分合并，进行蒸馏，收集180～190℃的馏分，得二乙酸乙二醇酯（1）80～90g，收集55%～61%。
