DODECYL benzene sulphonic acid was used in preparation of a
series of nonionic surfactants (II - V) a-c. The preparation was
completed by the reaction of dodecyl benzene sulphonic acid with
thionyl chloride followed by the alkylene diamine series (n = 2, 4, 6,
8) to give Ia-d, respectively. The later products (Ia –d) were reacted
with ethylene oxide to produce nonionic surfactants (II - V) a-c. The
structures of the prepared nonionic surfactants were confirmed by IR
and 1HNMR spectra. The surface properties, biodegradability and
biological activities of the prepared compounds were investigated.
The obtained data show that these compounds have good surface and
biological activities besides, reasonable biodegradability properties. |
