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.

Abstract: N-Methyl-2-pyrrolidone (NMP) is prepared by preparing a mixture comprising monomethylamine, dimethylamine and trimethylamine and ammonia in a first process step by reacting ammonia with methanol at elevated temperature in the presence of a catalyst, separating 10 off the ammonia, reacting the mixture comprising the methylamines with gamma-butyrolactone (gamma-BL), in a molar ratio of monomethylamine to gamma-BL of at least 1 in a second process step at elevated temperature and superatmospheric pressure, separating NMP and unreacted methylamines from the reaction product and returning unreacted methylamines to the first process step for reaction with methanol and ammonia.
