Cyclization of diols with ammonia over CuO-ZnO-Al2O3 catalyst in the presence of H2

Article abstract of DOI:10.1007/BF00707239

Cyclization of diols with ammonia in an H2 atmosphere over an industrial CuO-ZnO-Al2O3 catalyst for the synthesis of methanol (SNM-1) gives nitrogen-containing five-, six-, or seven-membered heterocyclic compounds.The yields of cyclic amines in the 180-230 deg C temperature range are 46 to 97 percent. - Keywords: diols, ammonia, cyclization, heterocyclic amines, copper-containing catalyst
