- HIGHLY SOLUBLE TRIS-(2,3-EPOXYPROPYL)-ISOCYANURATE AND METHOD FOR PRODUCING SAME
-
There is provided an epoxy composition which has difficulty in precipitating a crystal during storage, is homogeneous and can be stored for a long period; and a cured product of the composition having excellent transparency, heat resistance, and light resistance can be obtained on curing. An α-type tris-(2,3-epoxypropyl)-isocyanurate crystal comprising β-type tris-(2,3-epoxypropyl)-isocyanurate in the crystal in a ratio of 2% by mass to 15% by mass. A method for producing the α-type tris-(2,3-epoxypropyl)-isocyanurate crystal comprising step (i) separating β-type tris-(2,3-epoxypropyl)-isocyanurate contained in a tris-(2,3-epoxypropyl)-isocyanurate solution from the solution as a solid to obtain a crystal with an increased content ratio of α-type tris-(2,3-epoxypropyl)-isocyanurate.

- Study of methods of preparation of 1,4-diglycidyltetrazolone. New synthesis of triglycidylisocyanurate
-
1,4-Diglycidyltetrazolone was synthesized for the first time by the reaction of tetrazolone and epichlorohydrin with subsequent treatment of the products of addition with a base. The basic directions of the reaction of carbamoyl azide with epichlorohydrin, which yields triglycidylisocyanurate and diglycidylcarbamoyl azide, were investigated. The features of the synthesis and properties of the substances obtained were described. 1996 Plenum Publishing Corporation.
