    Abstract: (a) Zeolites, (b) aluminosilicates, (c) phosphates prepd. hydrothermally, (d) meso-porous oxides with high surface area, (e) pillared interlayered clays, (f) amorphous oxides prepd. by the sol-gel process and/or (g) acid-treated foliated silicates are used as the heterogeneous catalyst in the prepn. of amines (I) by reacting mixt. obtd. by cracking petroleum fractions (II) with NH3 or prim. or sec. amines of formula HN(R )R (III) at 200-350 degrees C and 100-300 bar; (in which R , R = H, 1-20 C alkyl, 2-20 C alkenyl, 2-20 C alkynyl, 3-20 C cycloalkyl, 4-20 C alkyl-cycloalkyl, 4-20 C cycloalkyl-alkyl, aryl, 7-20 C alkylaryl or 7-20 C aralkyl; or R , R = a 2-12 C alkylene di-chain).
