低い２−（ジメチルアミノメチル）−グルタロニトリル（ＤＧＮ）含量を有する３−ジメチルアミノプリオニトリル（ＤＭＡＰＮ）および低い２−（ジメチルアミノメチル）−グルタロニトリル（ＤＧＮ）含量を有する３−ジメチルアミノプロピオニトリル（ＤＭＡＰＮ）から３−ジメチルアミノプロピルアミン（ＤＭＡＰＡ）を製造する方法

摘要

Preparing 3-dimethylaminopropylamine (DMAPA) comprises reacting 3-dimethylaminoprionitril (DMAPN) with hydrogen in the presence of a catalyst, where the used DMAPN has a content of 2-(dimethylaminomethyl)-glutaronitrile (DGN) of 300 ppm by weight or less, based on the used DMAPN. An independent claim is also included for a mixture comprising DMAPN and DGN in a molar ratio of 1000000:5-1000000:250.
