摘要：
3,4,6-trifluorophthalic acid is prepared in high yield by reaction of a 3,4,6-trichloro-N-substituted phthalimide with potassium fluoride at temperatures in the range of 200.degree. to 270.degree. C. in the absence of a catalyst to form the corresponding trifluoro-N-substituted phthalimide which, in turn, is hydrolyzed to form the 3,4,6-trifluorophthalic acid.
