Abstract
NEW MATERIAL:A 4,4'-bis(alkoxybenzoyl)diphenyl ether shown by formula I (R is alkyl; Ar is aromatic residue and alkoxy is bonded to para- or ortho- position of ketone group). EXAMPLE:4,4'-Bis(4-methoxybenzoyl)diphenyl ether. USE:A precursor for 4,4'-bis(hydroxybenzoyl)diphenyl ether, a monomer for heat- resistant polymers, an ultraviolet light absorber and a sensitizer. PREPARATION:A 4,4'-bis(nitrobenzoyl)diphenyl ether shown by formula II (nitro group is bonded to para- or ortho-position of ketone group) is reacted with an alkali metal alkoxide shown by formula III (R is alkyl; M is alkali metal) to give 4,4'-bis(alkoxybenzoyl)diphenyl ether shown by formula I.
