The invention relates to alkylated amine compounds of formula:
H
R1-N-R2 where R, is selected from alkyl groups containing an odd number of carbon atoms in the range 7 to 17 carbon atoms and where R2 comprises an alkyl group containing from 1 to 4 carbon atoms. In a preferred embodiment R1 is a long chain alkyl group containing 13 or 15 carbon atoms, the groups being both straight chain and branched, the amount of branching being in the range 30 to 70%, and R2 is a methyl group. The alkylated amine compounds are conveniently prepared to a purity of at least 95 % by reaction of an aldehyde R1.CHO and an amine R2.NH2 in the presence of a suitable catalyst, for example Raney nickel or rhodium catalysts.
本发明涉及式中的烷基化胺化合物:
H
R1-N-R2 其中 R 选自含有 7 至 17 个碳原子的奇数个碳原子的烷基,R2 包括含有 1 至 4 个碳原子的烷基。在一个优选的实施方案中,R1 是含有 13 或 15 个碳原子的长链烷基,该基团既可以是直链的,也可以是支链的,支化量在 30% 至 70% 之间,R2 是甲基。通过醛 R1.CHO 和胺 R2.NH2 在合适的催化剂(例如雷尼镍或铑催化剂)存在下反应,可以方便地制备纯度至少为 95% 的烷基化胺化合物。
