In this paper, the chemical structure of pectin has been
modified by reacting of carboxyl group in pectin with tetrabutyl
ammonium hydroxide [TBA-OH], (acid-base) reaction, to change
hydrophilic properties by adding hydrophobic alkyl chains to the
polymer chain in pectin, Some physical properties of both: pectin
and tetrabutyl ammonium pectin; has been determined by
measuring the Kinematic viscosity, degree of turbidity and density
of their water solutions at different concentration.
