Abstract
본 발명은 일반식(Ⅰ)의 화합물과 일반식(Ⅱ)의 화합물을 폴리인산 용매하에서 염화지르토니움 촉매존재하에 감압하에 가열하여 반응시켜서 일반식(Ⅲ)의 폴리히드록시 벤조페논을 제조하는 방법에 관한 것이며,The present invention is to prepare a polyhydroxy benzophenone of the general formula (III) by reacting a compound of the general formula (I) and a compound of the general formula (II) by heating under reduced pressure in the presence of a zirconium chloride catalyst in a polyphosphate solvent It's about how
식중 R는 탄소수 1-4의 알킬기 또는 알콕시기이며, m 및 p는 1-5의 정수이며, m 및 n의 합이 m+n5이며, n 및 q는 1-4의 정수이며, p 및 q의 합이 p+q 5이다.Wherein R is an alkyl or alkoxy group having 1-4 carbon atoms, m and p are integers of 1-5, the sum of m and n is m + n5, n and q are integers of 1-4, p and q The sum of is p + q 5.
본 발명의 방법으로 목적화합물을 온화한 조건하에 높은 수율 및 순도로 제조할 수 있다.The process of the present invention allows the preparation of the desired compound in high yield and purity under mild conditions.
