| abstract |
FIELD: chemistry. n SUBSTANCE: invention relates to 2-[4'-(2",6"-dimethylphenoxy)benzoyl]benzoic acid which can be used as a by-product in the synthesis of polyarylene phthalides with valuable properties. A method for preparing acid I in 77% yield from 2-(4'-fluorobenzoyl) benzoic acid and 2.6-dimethylphenol in the presence of K 2 CO 3 with two-stage heating: first in a mixture of N,N-dimethylacetamide with chlorobenzene until the azeotropic distillation of water and chlorobenzene is completed, then only in N,N-dimethylacetamide. n EFFECT: increased quality of output. n 3 cl, 3 ex |
