で表わされる新規なパラヒドロキシ安息香酸ドコ
シルエステルに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention is based on the formula This invention relates to a novel parahydroxybenzoic acid docosyl ester represented by:
本発明の化合物は、たとえばパラヒドロキシ安
息香酸とドコシルアルコールを適当な溶媒（トル
エン、ベンゼン、クロロホルム、ジクロロメタン
など）に溶かし、ルイス酸（塩化アルミニウム、
四塩化スズなど）やプロトン酸（濃硫酸など）の
酸触媒の存在下に反応させることにより得ること
ができる。 The compound of the present invention can be prepared by dissolving parahydroxybenzoic acid and docosyl alcohol in a suitable solvent (toluene, benzene, chloroform, dichloromethane, etc.) and preparing a Lewis acid (aluminum chloride, dichloromethane, etc.).
It can be obtained by reacting in the presence of an acid catalyst such as tin tetrachloride, etc.) or a protic acid (concentrated sulfuric acid, etc.).
また、パラヒドロキシ安息香酸の反応性誘導体
