ABSTRACT:
A process for producing 1,3-bis(3-aminophenoxy)-benzenes which are very useful as a monomer for heat-resistant high molecular weight polymers is provided, which process comprises dehalogenating a bis(3-aminophenoxy)-halogenobenzene by its reduction, which compound is selected from the group consisting of 1,3-bis(3-aminophenoxy)-5-halogenobenzenes, 1,3-bis(3-aminophenoxy)-2,4-dihalogenobenzenes and 1,5-bis(3-aminophenoxy)-2,4-dihalogenobenzenes, these raw material compounds being respectively obtained by reacting a 1,3,5-trihalogenobenzene, a 1,2,3,4-tetrahalogenobenzene or a 1,2,4,5-tetrahalogenobenzene with 3-aminophenol in the presence of a dehydrohalogenating agent.
