N-亚异丁基异丁胺

反应条件: temp:-15.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 1000g isobutyraldehyde and about 100 g of a commercially available nickel containing carrier catalyst (containing about 52 to 53% by weight nickel, and employing chromium (3)-oxide as activator) are introduced into a 2 l three-necked flask, equipped with a gas inlet tube, a stirrer and a reflux condensor, and cooled to -15° C. Hydrogen and ammonia are introduced into the resulting suspension in a volume ratio of 1 : 1 and at a temperature of 90° C. 160 l of gas are introduced per hour. Altogether, 240 l hydrogen and 240 l gaseous ammonia are introduced. After termination of the reaction, the catalyst is separated by filtration. 889 g isobutylidene -- isobutylamine are obtained. are introduced into a 2 l three-necked flask equipped with a gas inlet tube, a stirrer After termination of the reaction the catalyst is separated by filtration
