先減壓蒸餾,再通過高真空薄膜蒸發(fā)器蒸餾除出環(huán)氧氯丙烷,粗產(chǎn)品再經(jīng)過結(jié)晶,離心,粉碎和烘干后得到電子級異氰尿酸三縮水甘油酯.處理方法,能有效提高TGIC產(chǎn)品純度,可以將TGIC的純度由92%提高到99%以上,達到電子級水平.

TGIC中殘留環(huán)氧氯丙烷是難揮發(fā)性材料中的揮發(fā)性組分,頂空分析適用此類物質(zhì)。浩瀚色譜（山東）應用技術(shù)開發(fā)有限公司實驗采用靜態(tài)頂空分析,內(nèi)加法定量.



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.
