Synthesis method of high-purity tris (glycidyl) isocyanurate

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%.

Method for synthesizing TGIC and coproducing ECH from dichloropropanol

The invention provides a method for synthesizing TGIC and coproducing ECH from dichloropropanol. The method comprises the following steps: (1) proportionally adding cyanuric acid, dichloropropanol, aquaternary ammonium salt phase transfer catalyst and water, heating and stirring the mixture and carrying out temperature control reaction in stages, heating and stirring the mixture to a certain temperature, carrying out heat preservation reaction for a period of time, heating the mixture, carrying out heat preservation reaction for a period of time, and cooling a reaction product; (2) in the reaction system in the step (1), adjusting the vacuum degree, dropwise adding liquid caustic soda while carrying out steam stripping with water within a certain period of time, carrying out heat preservation reaction for a period of time after dropwise adding is finished, and then removing solid salt through plate-and-frame filter pressing; (3) carrying out reduced pressure distillation on the filtrate obtained in the step (2) to remove ECH, and collecting a crude product TGIC from the kettle liquid; (4) recrystallizing the crude product TGIC in an organic solvent for a period of time under a low-temperature condition, and then centrifugally separating, washing and drying the product to obtain a TGIC product. According to the treatment method disclosed by the invention, the cost of TGIC can be effectively reduced, an important organic chemical raw material ECH is co-produced, and the method is low-carbon and environment-friendly.

Electronic grade of a kind of preparation method of three isocyanuric acid glycidyl (by machine translation)

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.
