Abstract: Preparation of alkanolamine with improved color properties comprises treating an alkanolamine with water using a heterogeneous hydration catalyst containing Ru, Re, Rh, Pd, Os, Ir, Pt and/or Ag and a support from active carbon, alpha Al2O3, ZrO2 and Ti oxide at high temperature, the cutting hardness being at least 10 N, the side pressure resistance being at least 30 N and the stamp hardness being at least 25 N when the support is active carbon.
