正丁醛含量的气相色谱法测定 详细信息：



 丁醛是重要的有机化工产品,主要用于制造树脂、增塑刹、硫化促进剂等。丁醛中主要杂质有水、巴豆醛、丁酸及微量的乙醛、乙醇、丙酮等。丁醛含量为95％以上,用化学分析难度较大,准确度也差。

浩瀚色谱（山东）应用技术开发有限公司经过试验,选用聚乙二醇色谱柱FID气相色谱仪对杂质进行色谱定量后,用差减法计算丁醛含量,获得了较为满意的结果,大相对偏差为5.26％。

Determination of n-butyraldehyde content by gas chromatography
Determination of n-butyraldehyde content by gas chromatography

Name: Capillary Column
Fixing fluid: polyethylene glycol
Specification: 30m*0.32mm*0.5um
Model: PEG-20M
Application: Industrial n-butyraldehyde


  Butyraldehyde is an important organic chemical product, mainly used in the manufacture of resins, plasticized brakes, vulcanization accelerators, etc. The main impurities in butyraldehyde are water, crotonaldehyde, butyric acid and trace amounts of acetaldehyde, ethanol, acetone, etc. The butyraldehyde content is more than 95%, so it is difficult to use chemical analysis and the accuracy is also poor.

After testing, Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. used a polyethylene glycol column FID gas chromatograph to chromatographically quantify the impurities, and then calculated the butyraldehyde content by the subtraction method. A satisfactory result was obtained. The maximum relative deviation was 5.26%.
