Cycloalkanebis(methylamine)isomerization |
| abstract |
THE ISOMER RATIO IN A NON-EQUILIBRATED MIXTURE OF THE CIS AND TRANS ISOMERS OF A C6-C14 CYCLOALKYLANEBIS(METHYLAMINE9 SUCH AS 1,4-CYCLOHEXNEBIS(METHYLAMINE) CAN BE CONVENIENTLY ALTERED BY CONTACTING THE MIXTURE AT 175*290*C. WITH HYDROGEN IN THE PRESENCE OF A HYDROGENATION CATALYST AND AMMONIA. A HIGH YEILD OF ONE OF SUCH ISOMERS CAN BE OBTAINED BY SIMILARLY CONTACTING A MIXTURE OF SUCH ISOMERS WHEREIN THE RATIO OF SAID ONE ISOMER TO THE OTHER OF SAID ISOMERS IS LOWER THAN THE CORRESPONDING EQUILBRIUM RATIO OF SUCH ISOMERS, SELECTIVELY SEPARATING SAID ONE ISOMER FROM THE CONTACTED MIXTURE AND RECYCLING THE RESIDUAL MIXTURE FOR MORE OF SUCH CONTACTING. |
