Abstract
본 발명은 자외선흡수제와 감광수지원료 등으로 널리 쓰이는 다음 구조식(Ⅰ)로 표시되는 벤조폐논 유도체의 제조방법에 관한 것으로, 1,4-디옥산 용매를 사용함을 특징으로 하여, 촉매로서 삼염화인과 염화아연 존재하에 구조식(Ⅱ)의 방향족 카르복실산 화합물 1당량에 대하여 구조식(Ⅲ)의 화합물 1∼15당량을 반응시켜서 구조식(Ⅰ)의 목적화합물을 제조하는 새로운 방법을 제공한다.The present invention relates to a method for preparing a benzophenone derivative represented by the following structural formula (I), which is widely used as a UV absorber and a photosensitive support material. There is provided a new method for preparing the desired compound of formula (I) by reacting 1 to 15 equivalents of compound of formula (III) with 1 equivalent of aromatic carboxylic acid compound of formula (II) in the presence of zinc chloride.
상기식에서, n은 1 내지 3의 정수이고, R1및 R2는 각각 수소 또는 메틸기이다.Wherein n is an integer of 1 to 3, and R 1 and R 2 are each hydrogen or a methyl group.
본 발명은 새로운 용매조건인 1, 4-디옥산을 사용함으로써, 종래의 기술에 비하여 반응조건이 온화하며, 고순도, 고수율로 상기 구조식(Ⅰ)의 목적화합물을 제조할 수있는 경계적인 방법을 제공한다.The present invention uses a new solvent condition, 1, 4-dioxane, the reaction conditions are milder than the prior art, a boundary method for producing the target compound of the formula (I) in high purity, high yield to provide.
