Abstract

본 발병은 액상 자외선 안정제인 2-에틸헥실-P-메톡시신나메이트의 새로운 제조방법에 관한 것으로, 메탄올 용매 중에서 p-아니스알데하이드와 메틸아세테이트를 NaOCH3촉매하에 반응시켜서 메틸-p-메톡시신나메이트를 합성시킨 후, 이를 아세트산 아연(Zinc Acetate) 촉매하에 2-에틸헥사놀과 반응시켜서 제조하는 바, 저렴한 원료물질을 사용하여 간단한 공정으로 경제적으로 위 목적물질을 제조하는 새로운 방법을 제공한다.The present invention relates to a novel method for preparing 2-ethylhexyl-P-methoxycinnamate, a liquid ultraviolet stabilizer, by reacting p-anisaldehyde and methyl acetate in a methanol solvent under a NaOCH 3 catalyst to methyl-p-methoxycinna. After the mate is synthesized and reacted with 2-ethylhexanol under zinc acetate (Zinc Acetate) catalyst, it provides a new method for economically preparing the target substance in a simple process using inexpensive raw materials.
