METHOD FOR PREPARING N,N-DIGLYCIDYLALKYLAMINE IN IMPROVED YIELD AND PURITY AND AT REDUCED COST BY USING ALKYLAMINE AND EPIHALOHYDRIN

摘要

PURPOSE: A method for preparing N,N-diglycidylalkylamine by using alkylamine and epihalohydrin is provided. The preparation method thereof is carried out at room temperature without using phase transition catalyst. Therefore, the yield and purity of N,N-diglycidylalkylamine are improved. CONSTITUTION: The method for preparing N,N-diglycidylalkylamine represented by the formula(1) comprises the steps of: reacting alkylamine with epihalohydrin at atmospheric pressure and 10 to 100 deg. C in the absence of solvent and catalyst to prepare N,N-bis(3-halo-2-hydroxypropyl) alkylamine; and reacting the N,N-bis(3-halo-2-hydroxypropyl) alkylamine with an alkali metal compound, wherein R is saturated alkyl or unsaturated alkyl containing carbohydrate or carbon fluoride, or aromatic ring containing alkyl.
