Condensation products of diphenyl ether with iso- or terephthalic diesters and process for their preparation |
| abstract |
Cpds. such as 4-(4-carbomethoxybenzoyl)-diphenyl ether or 4,4'-bis-(4-carbomethoxybenzoyl)-diphenyl ether are produced by reacting diphenyl ether and lower alkyl- or isoalkyl ester of iso- or terephthalic acid in presence of polyphoric acid the temp, according to required product, varying from 60-120 to 165-180 degrees C. |
