Scheme 5.7
Synthesis of a gemini surfactant (C11) through epoxy chloropropane
Rosin acid reacted with epoxy chloropropane in alkaline conditions to form the
corresponding ester with an epoxy group, which reacted with amine to form a
tertiary amine, and then reacted with halide to form quaternary ammonium salt
cationic surfactants (C12-C13,
Scheme 5.8
). Rosin acid reacted with an epoxy group
quaternary ammonium salt to form cationic surfactants directly (C14) (
Scheme 5.9
)
[20].
