Abstract
Optically active &bgr;-type tris-(2,3-epoxypropyl)-isocyanurate is obtained by a method of reacting isocyanuric acid with an optically active epihalohydrin, or a method of optically resolving a racemic modification of tris-(2,3-epoxypropyl)-isocyanurate by using an amylose or cellulose derivative. It is a method for producing a high melting point type tris-(2,3-epoxypropyl)-isocyanurate obtained by mixing two enantiomers of optically active &bgr;-type tris-(2,3-epoxypropyl)-isocyanurate.
