摘　　要：聚四亚甲醚二醇的生产工艺是以四氢呋喃和醋酐在非均相催化剂存在下发生聚合反应生成中间体聚四亚甲基醚二乙酸酯。文章根据红外光谱谱图中出现特征峰的位置,判断生产中引起聚四亚甲基醚二醇羰基比形成的原因,以达到快速排查生产过程中羰基比升高的原因,从而控制产品质量。The production process of poly(tetramethylene ether glycol)is based on the polymerization of tetrahydrofuran and acetic anhydride in the presence of heterogeneous catalyst to produce the intermediate poly(tetramethylene ether diacetate).According to the position of the characteristic peak in the infrared spectrum,the reason for the formation of polytetramethyl ether glycol carbonyl ratio in production is judged.In order to quickly check the reasons for the increase of carbonyl ratio in the production process,so as to control the quality of the product.
