Determination of Residual Epichlorohydrin in TGIC by Headspace Gas Chromatography
Headspace Gas Chromatographic Determination of Residual Epichlorohydrin in TGIC Details:

Name: capillary column
Stationary Phase: 5% Phenyl-95% Methylpolysiloxane
Specifications: 30m*0.32mm*0.5um
Model: HH-5
Application: Headspace Gas Chromatographic Determination of Residual Epichlorohydrin in TGIC

First vacuum distillation, then through high vacuum thin film evaporator distillation to remove epichlorohydrin, the crude product is then crystallized, centrifuged, pulverized and dried to obtain electronic grade triglycidyl isocyanurate. The treatment method can effectively Improving the purity of TGIC products can increase the purity of TGIC from 92% to more than 99%, reaching the electronic level.

Residual epichlorohydrin in TGIC is a volatile component in less volatile materials, which is suitable for headspace analysis. The experiment of Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. adopted static headspace analysis and internal addition quantification.
