HCID 11320920Chromium 22, nickel 78 (atomic)Catalyst

Procedure

The procedure of Example 1 was followed except that 50.0 g of 1-isopropyl-2-methylimidazoline and about 5 g of Raney Nickel-chromium catalyst was charged. GLC analysis showed that 98% yield of 1-isopropyl-2-methylimidazole was obtained with >99% conversion of imidazoline.
