ABSTRACT
The thesis deals with the synthesis and characterization of surfactants derived
from natural products. Physico-chemical properties, such as solubility and
melting points, and surfactant properties, such as dispersion, emulsification,
wetting and foaming were investigated.
A number of surfactants was synthesized from sugars and natural hydrophobic
compounds. harides, incl. D-glucose, 2-deoxy -2-amino-D-glucose, D-
fructose and D-(+)-glucono-1,5-lactone, were used for the hydrophilic moiety of
the surfactants. The hydrophobic moiety consisted of steroids, monoterpenes,
rosin acids, fatty acids and long chain alkyl groups, as well as aromatic
compounds. In general, the synthetic procedures gave relatively high yields in
few steps. Some novel surfactants were prepared in high yields in one simpl
