METHOD OF PRODUCING SYMMETRICAL GEM-DIAMINES |
| 摘要 |
FIELD: chemistry. ^ SUBSTANCE: proposed invention relates to a method of producing symmetrical gem-diamines with general formula where , involving reacting secondary acyclic or cyclic amines R2NH with excess N,N,N1,N1-tetramethyl methanediamine in the presence of a copper chloride (CuCl) catalyst at temperature 80C and atmospheric pressure for 2-4 hours. Output of symmetrical gem-diamines is 85-98%. ^ EFFECT: improved method. ^ 2 dwg, 7 ex |
