Process for the synthesis of twin-tail triamines

A method for producing a twin-tail triamine having the formula (I)

• characterized in that in a first method step a diamine having the formula (II)
• is reacted with an aldehyde having the formula (III)
• to obtain an aldehyde having the formula (IV)
• which is further reacted, in a second method step, with an amine having the formula (V)
• under reductive amination conditions to obtain the twin-tail triamine according to formula (I), wherein
• R1 and R2 independently represent a C3-C27 aliphatic group,
• R3 and R4 either independently represent a C1-C8alkyl group, or are linked together to form a ring of formula
• wherein R4—R3 represents a divalent hydrocarbon radical containing from 2 to 10 carbon atoms,
• R5 and R6 either independently represent a C1-C8 alkyl group, or are linked together to form a ring of formula
• wherein R5-R6 represents a divalent hydrocarbon radical containing from 2 to 10 carbon atoms,
• R7, R8 and R9 independently represent hydrogen or a C1-C8 alkyl group, and
• E1 represents a linear or branched divalent hydrocarbon radical with 2 to 24 carbon atoms, which can be optionally substituted and/or interrupted by one or more heteroatom containing groups.
