PRODUCTION OF HYDROGENATED BISPHENOL A

摘要

PROBLEM TO BE SOLVED: To provide a method for producing hydrogenated bisphenol A with good efficiency by which a catalyst is prevented from deteriorating in continuous hydrogenation of bisphenol A using a fixed bed flow type reactor. SOLUTION: A solution containing 2-15 wt.% of bisphenol A in an alcoholic solvent or a solution of the bisphenol A treated with an oxide or a hydroxide of an alkaline earth metal is fed to a fixed bed flow type reactor using a supported nickel formed catalyst and continuously catalytically hydrogenated.
