ABSTRACT:
A process for preparing glycidylphtalimide or it optically active compound by reacting a phthalimide alkalimetal salt with an epihalohydrin or an optically active epihalohydrin in an alcohol solvent; or by reacting phthalimide with an epihalohydrin or an optically active epihalohydrin in the presence of an alkali metal carbonate, an alkali metal hydrogencarbonate or a quaternary ammonium salt to obtain a N-(3-halogeno-2-hydroxypropyl)phthalimide and then by cyclizing the product with an alkali metal alkoxide.
