摘　　要：研究了三甘醇在Raney镍催化下,直接还原胺化生成1,8-二氨基-3,6-二氧杂辛烷的反应。结果表明反应条件对产物组分及结构具有较大的影响:催化剂用量大会导致醚键断裂的副反应;氢压的增加会生成较多的二氮杂18-冠醚-6副产物;液氨量的增加可抑制副反应的发生。1,8-Diamino-3,6-dioxaoctane was prepared from the catalytic amination of triethylene glyco in the presence of Raney nickel.The results showed that various reaction conditions significantly affect the composition and structure of products： first,the enhanced amount of catalyst would lead to the cleavage of ether bond;second,more 4,13-diaza-18-crown-6-ether would be produced with hydrogen pressure elevating;finally,the increase of liquid ammonia would prevent the generation of by-products.
