Synthesis method of high-purity tris (glycidyl) isocyanurate
-
Paragraph 0027-0059, (2021/07/14)
The invention discloses a synthesis method of high-purity tris (glycidyl) isocyanurate. The method comprises the following steps: (1) adding cyanuric acid, a catalyst and a polar solvent into a reactor, and uniformly mixing; (2) dropwise adding epoxy chloropropane to react with cyanuric acid, and separating to obtain an intermediate; (3) reacting the intermediate and calcium oxide in an organic medium; and (4) separating while the product is hot, removing solids, cooling and crystallizing the liquid, and separating to obtain the product TGIC. According to the method, the hydrolysis side reaction of the product and an intermediate product is effectively controlled, so that the product yield reaches 96% or above, and the purity reaches 99%.

Paragraph 0026; 0039, (2017/01/17)
The invention belongs to the technical field of chemical preparation, in particular relates to a preparation of electronic grade isocyanuric acid new method for three-glycidyl ester. The invention relates to a method of preparation of electronic grade TGIC, by the prior art conventional in the preparation is carried out by the two-step, cyanuric acid is a commonly used as the raw materials of reaction with epichlorohydrin, and creativity in the synthetic reaction step, by adding methanol as a cosolvent, ECH solid phase cyanogen uric acid and liquid phase in order to promote a non-homogeneous reactions are carried out, and because the cyclization reaction step of the addition of the methanol, effectively reduces the amount of the feeding ECH, thereby greatly improving the efficiency of recovery ECH, and reduce the energy consumption of the unit consumption of ECH.
