摘要：
A preparation process of a bis(3-nitrophenoxy) compound represented by the formula: ##STR1## wherein X is a direct bond, divalent hydrocarbon having from 1 to 10 carbon atoms or a divalent group selected from --C(CF.sub.3).sub.2, --CO--, --S--, --SO--, SO.sub.2 --or --O--, which comprises reacting 4,4'-bisphenol with m-dinitrobenzene in the presence of an alkali metal carbonate or alkali metal hydrogen carbonate having a particle size of 250 .mu.m or less while removing generated water from the reaction system during the reaction. In one embodiment of the process, the reaction is carried out while simultaneously adding 4,4'-bisphenol and m-dinitrobenzene to a reaction vessel which was previously charged with the base and an aprotic polar solvent.
