制备方法与用途

理化性质

聚四氢呋喃是一种易溶于醇、酯、酮、芳烃和氯化烃，而不溶于脂肪烃和水的白色蜡状固体。当温度超过室温时，它会变成透明液体。

应用

作为重要的化工原料，聚四氢呋喃在化纤领域主要用于制备氨纶，在非纤领域用于制备弹性体、胶黏剂、涂料、密封剂等产品。使用聚四氢呋喃制备的聚氨酯产品耐磨、耐化学腐蚀，并具有良好的柔韧性和回弹性。目前，在国外，聚四氢呋喃用量最大的前三类依次是：聚氨酯弹性纤维（49%）、聚氨酯弹性体（36%）和酯醚共聚弹性体（15%）。

制备

以高氯酸作催化剂，酸酐作为封端剂，在低于25℃的条件下进行聚合反应。然后加入氢氧化钠溶液终止反应，通过蒸馏脱除未反应的四氢呋喃和水，并用水洗去聚合物中的盐分。接下来，进行蒸馏脱水得到聚四氢呋喃醚二醇酯酸酯。之后，在甲醇中进行酯交换反应，加水中和后，蒸发多余的甲醇和酯酸甲酯，制得粗品最后通过再次脱水得到纯的聚四氢呋喃。

用途

PTMEG广泛用于生产TPU、CPU、PU树脂、PU浆料以及聚氨酯弹性体等。作为生产氨纶和聚氨酸弹性体的重要原料之一，PTMEG用作氨酯中的软段，提供聚氨酯产品良好的耐水解性、耐低温性和动态性能。同时，它也可作为合成革用树脂、弹性纤维（氨纶）的主要原料。

摘要：

在甲醇、乙醇、正丙醇、正丁醇、2-丙醇、2-甲基-1-丙醇和 2-甲基-2-丙醇等不同醇类存在的情况下，对使用三酸铝作为氧化丁烯（BuO）的开环催化剂进行了评估。通过改变温度、催化剂浓度和甲醇氧化丁烯摩尔比，对与甲醇的反应进行了动力学研究。这些反应产生了两种主要产物（2-甲氧基-1-丁醇和 1-甲氧基-2-丁醇），比例约为 1:1。我们注意到，在催化剂浓度较低（5 ppm）、温度较低（90 °C）、MeOH-BuO 摩尔比为 8:1 的条件下，反应的选择性可以通过动力学调节，使产物比例向 1-甲氧基-2-丁醇（即 α-烷氧基乙醇）转移。实验设计程序证实了这一结果。利用实验设计数据进行的统计计算确定了一个可行的区域，在该区域内可以与甲醇进行反应，从而使 1-甲氧基-2-丁醇的选择性略高。该区域表明，甲醇与氧化丁烯的比例应为 8:1，温度应在 80 至 85 ℃ 之间，催化剂浓度应在 3.9 至 5 ppm 之间。利用这些反应条件与甲醇和一系列醇类进行了试验反应。在这些条件下，除 2-甲基-2-丙醇外，所有醇都与环氧丁烯发生了反应，对 α-烷氧基乙醇的选择性高于对 β-烷氧基乙醇的选择性。要与 2-甲基-2-丙醇发生开环反应，需要在 80 °C 的温度下使用较高的催化剂浓度（约 10 ppm）和较低的氧化醇丁烯比（6:1）。该反应生成了 1-叔丁氧基-2-丁醇和 2-叔丁氧基-1-丁醇的混合物，由于笨重的叔丁氧基基团的立体影响，α-烷氧基乙醇的选择性更高。
