聚甲氧基二丁基醚含量的检测方法
摘要：
本发明公开了一种聚甲氧基二丁基醚含量的检测方法。该方法包括以下步骤：(1)卡尔费休法测定聚甲氧基二丁基醚混合物中的水分含量；(2)酸碱滴定测定聚甲氧基二丁基混醚合物中的甲醛含量；(3)离心脱水；(4)设定气相色谱检测条件；(5)检测分析。本发明方法可有效提升检测的准确度，延长气相色谱使用寿命。
摘要（英）：

The invention discloses a detection method for content of polyoxymethylene dibutyl ether. The method comprises the following steps: (1) determining the content of water in a polyoxymethylene dibutyl ether mixture by adopting a karl-fischer method; (2) determining the content of formaldehyde in the polyoxymethylene dibutyl ether mixture through acid-base titration; (3) centrifuging and dehydrating; (4) setting gas chromatography conditions; and (5) detecting and analyzing. By adopting the method, the detection accuracy can be effectively promoted, and the service life of gas chromatography can be prolonged.
