HYDROGENATION METHOD FOR PREPARING HYDROGENATED BISPHENOL-A HAVING A HIGHER TRANS/TRANS ISOMER RATIO

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%.
