|Title:||Catalytic hydrogenation of tetrahydrophthalic anhydride|
|Abstract:||Catalytic hydrogenation reaction of tetrahydrophthalic anhydride(THPA) to hexahydrophthalic anhydride(HHPA) has been studied. The effects of temperature, pressure, time and solvent on catalytic reaction have also been investigated. Raney Ni(T-1 ) has high activity towards hydrogenation of THPA to HHPA. The amount of HHPA formed constantly increases with increasing temperature in the experimental temperature range (70-1 00°C). The experimental results show that conversion of THPA and selectivity to HHPA reach 88% and 100%, respectively under the appropriate reaction conditions (T-1 Raney Ni: 7%, H2 pressure: 4.5 MPa, 45% DMF solution, reaction time 3.0h, temperature: 95°C).|
