Page/Page column 8, (2008/06/13)
An industrially advantageous process is presented whereby a high purity anthracene diether can be produced in good yield. An aqueous medium containing an alkali salt of 9,10-anthracenediol is added to an organic solvent containing an etherifying agent in the presence or absence of a quaternary ammonium compound or a quaternary phosphonium compound, to carry out the etherifying reaction to produce the anthracene diether.
