Determination of epichlorohydrin content in polar dry rubber production
Determination of epichlorohydrin content in polar dry rubber production Details:

Name: capillary column
Stationary phase: 6% nitrile propylphenyl 94% dimethylpolysiloxane,
Specifications: 30m*0.53mm*0.3um
Model: HH-624

In the process of producing polarized SBS, epichlorohydrin, an important intermediate, needs to be introduced, and the content of epichlorohydrin in each link directly affects the production process and the quality of the product.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has researched and tested the determination of epichlorohydrin in each process of polar dry rubber production by gas chromatography. The test results show that: under certain chromatographic conditions, epichlorohydrin The samples obtained in the previous step were well separated. The quantitative analysis was carried out by the working curve method, the relative standard deviation was 4.7%-6.4%, the recovery was 98.0%-105%, and the minimum detection limit was 0.05 mg/L.
