HH-TRI 三聚甲醛分析填充柱的详细介绍
三聚甲醛分析填充柱
三聚甲醛中含有甲醛、水、甲醇、甲酸甲醋、甲缩醛、二聚甲醛二甲醚等杂质,它们对本体聚合反应都有一定影响’l。因此,建立精三聚甲醛中微量杂质的快速分析方法,对于指导三聚甲醛的精制和聚合操作具有重要意义。 虽然精三聚甲醛中的微量水可采用卡尔.费休法来测定。
滕州市浩瀚色谱仪器技术服务有限公司,采用三聚甲醛分析填充柱快速定量测定精三聚甲醛中微量水、甲醇、甲醛和甲缩醛等杂质的气相色谱分析方法。杂质含量为10~1000ppm 范围时,分析误差为±6.2~14.0%。此法适合用作三聚甲醛精制操作中成品的常规控制分析。

Packed column for analysis of paraformaldehyde
Trioxane co ntains impurities such as formaldehyde, water, methanol, methyl formate, methylal, dioxymethylene dimethyl ether, etc., all of which have a certain influence on the bulk polymerization reaction. Therefore, the establishment of a rapid analysis method for trace impurities in refined paraformaldehyde is of great significance for guiding the refining and polymerization operations of paraformaldehyde. Although the trace water in refined paraformaldehyde can be determined by Karl Fischer method.
Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd. adopts a trioxane analytical packed column to quickly and quantitatively determine trace water, methanol, formaldehyde, methylal and other impurities in refined trioxane by gas chromatography. When the impurity co ntent is in the range of 10~1000ppm, the analysis error is ±6.2~14.0%. This method is suitable for routine co ntrol analysis of finished products in the refining operation of trioxymethylene.
