Abstract: Process for producing 5- or 6-membered cyclic ethers (anhydropolyols) comprises subjecting polyols having at least 4 C atoms and at least 2 OH groups to cyclodehydration at at least 100 degrees C in the presence of water, an acid catalyst, an acid-stable hydrogenation catalyst and hydrogen. Preferably the reaction temperature is 100-380 degrees C, preferably 180-280 degrees C. The H2 pressure is 1-20 MPa, preferably 3-10 MPa. The hydrogenation catalyst comprises Ru, Rh, Pd and/or Pt as metals or metal compounds. The hydrogenation catalyst is used in an amount of 0.001-10 (preferably 0.01-1) wt.% based on the polyol. The acid catalyst is a 1-10C aliphatic carboxylic acid, preferably formic, acetic or propionic acid. The acid catalyst is used in an amount of 0.1-20 (especially 0.5-10) wt.% based on the polyol. The polyol is a tetritol, pentitol or hexitol.

Abstract: 3-Aminomethyl-3,5,5-trimethylcyclohexylamine (isophoronediamine) is a raw material which is used industrially for various synthetic resins. Isophoronediamine is used as a cis/trans isomer mixture, the cis/trans isomer ratio influencing the properties. The invention shows a way of controlling the isomer ratio in the preparation of isophoronediamine by aminating hydrogenation of 3-cyano-3,5,5-trimethylcyclohexanone (isophoronenitrile) in the presence of ammonia, H2 and a catalyst. The reaction is carried out in two temperature stages, namely first at 10 to 90 DEG C and then at 90 to 150 DEG C with a temperature difference between both stages of at least 30 DEG C, the contact time in the first stage being shorter than in the second. By lowering the temperature in the first stage the cis/trans ratio is increased.
