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

实验步骤: In this example, a sample of 2,2,5-trimethylpiperazine was prepared by substantially following the procedure set forth in Example II. However, in this example, 120 g of crude N-(2'-hydroxypropyl)-2-amino-2-methyl-1-propanol, 90 g of water, 60 g of a Ni-Cu-Cr catalyst, and 102 g of ammonia were charged. GLC analysis showed that a 48% yield of 2,2,5-trimethylpiperazine was obtained with 55% dialkanolamine conversion.
