Abstract
4,4'-diaminodiphenyl ether( DADPE) was synthesized by catalyzing the hydrogenation of 4,4'-dinitrodiphenyl ether( DNDPE) with supported KT-02 nickel catalyst,and the structure of DADPE was identified by melting point measurement and FT-IR analyses. The effects of temperature,pressure,stir speed and the amount of catalyst on hydrogenation reation were studied. The results show that conversion rate was up to 98%,reaction selectivity was 97% when the amount of catalyst KT-2 was 10%,the temperature was 90℃,the pressure was 2. 0MPa,time was 8h. The catalyst can be used for 8 times or more.
