Improved synthesis of partially N-hydroxyethylated tert-1,6-hexanediamine

摘要

Kind Code: A1 The present invention relates to a partially N-hydroxyethylated tert-1,6-hexanediamine based on a reaction that systematically uses precursor starting materials that do not contain halogen atoms and does not involve halogenated organic reactants. Provision of synthesis methods. The present invention relates to the following general formula (I): wherein the groups R 1, R 2 and R 3 are each selected indiscriminately from methyl and hydroxyethyl groups, and R 1, R 2 and R 3 A method for the synthesis of at least one nitrogen compound belonging to the family of partially N-hydroxyethylated tert-1,6-hexanediamine having at least one group of which is a methyl group, It relates to a method 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 is a straight chain of 6 carbon atoms in which 4 central carbon atoms are each bonded to 2 hydrogen atoms, and the alpha and omega carbon atoms are not bonded to halogen atoms. Including a carbon skeleton consisting of a chain arrangement. [Selection] Figure 1
