Abstract:
A hydrogenation method for preparing HBPA includes placing a BPA reaction liquid into a hydrogenation vessel with a hollow-shaft stirrer installed inside; starting the hollow-shaft stirrer to stir the BPA reaction liquid and simultaneously allowing hydrogen gas evenly distributed over and contact well with the BPA reaction liquid; in the presence of a single-metallic Ru/Al2O3 hydrogenation catalyst to proceed with a catalytic hydrogenation at low temperature and low pressure to produce HBPA, the HBPA has a yield of 99.7% or more, and particularly having a trans/trans isomer ratio above 63%.

Claim (Index 2):
The hydrogenation method as defined in  claim 1 , wherein at step d) the BPA reaction liquid before raising the temperature to 120 to 180\u00b0 C. is in advance stirred for 10 minutes under holding the pressure of step c) and at room temperature.
