HH-TRI//2m*1/8 trioxane detection packed column


Trioxane contains impurities such as formaldehyde, water, methanol, methyl formate, methylal, dioxymethylene dimethyl ether, etc., 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.
A gas chromatographic method for the rapid and quantitative determination of trace water, methanol, formaldehyde and methylal in refined trioxane. When the impurity content is in the range of 10～1000ppm, the analysis error is ±6.2～14.0%. This method is suitable for routine control analysis of finished products in the refining operation of trioxymethylene.
