摘　　要：1 Introduction Rosolic acid, also called as resinous acid, is a trihydroxyphenyl methane dye mainly used as an oxidation resistant indicator in acid-base titration with sharp color change depending on the pH, from 5.0（yellow） to 6.8（pink）. It is also used as an initial reactant in the syntheses of 4,4＇,4＂-tris（acyloxy）trityl chloride and its bromide for protection of primary hydroxyl groups, and a monomer in polyreaction to prepare color polymer fiber as pH probe.1 Introduction Rosolic acid, also called as resinous acid, is a trihydroxyphenyl methane dye mainly used as an oxidation resistant indicator in acid-base titration with sharp color change depending on the pH, from 5.0（yellow） to 6.8（pink）.
