The invention relates to a synthesis method for at least one nitrogen compound belonging to the family of partly N-hydroxyethylated tertiary 1,6-hexanediamines with general formula (I) as follows:
wherein radicals R1, R2, R3 are each selected indiscriminately among a methyl radical and a hydroxyethyl radical, and at least one radical among R1, R2, R3 is a methyl radical,
comprising at least a first reaction between a first halogen atom-free precursor compound and a second halogen atom-free precursor compound.
The first precursor compound comprises a carbon skeleton consisting of a linear sequence of 6 carbon atoms with the 4 central carbon atoms bonded each to 2 hydrogen atoms and the carbon atoms in alpha and omega position not bonded to a halogen atom.
本发明涉及至少一种属于部分 N-羟乙基化叔 1,6-己二胺家族的含氮化合物的合成方法,其通式(I)如下:
其中自由基 R1、R2、R3 可从甲基自由基和羟乙基中任意选择,且 R1、R2、R3 中至少有一个自由基为甲基自由基、
至少包括第一种不含卤素原子的前体化合物和第二种不含卤素原子的前体化合物之间的第一反应。
第一种前体化合物包括由 6 个碳原子的线性序列组成的碳骨架,其中 4 个中心碳原子分别与 2 个氢原子键合,α 和 ω 位置的碳原子不与卤素原子键合。
