This research includes a study of the triple-sentence equilibrium curves consisting of electrolytic acid and apple acid in a binary mixture of water and (hexane, ethanol, tetrahydrofuran)
Syria has produced cotton oil with large quantity like many other
countries.This position provides an impetus to develop oleochemical industries,
such as: fatty acids, fatty methylester, and fatty alkyl ester. These products can
be sulfonated with
SO٣ or HSO٣Cl. As a result, the obtained products have
interesting properities due to their good detergency, lower sensitivity to water
hardness, rapid degradability, and good skin mildness properties. Therefore,
they can be used when mixed with other detergents or soaps for house hold
purposes.
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.
The process of water infiltration into soil provides the soil and groundwater with
water. It also affects runoff formation and soil loss. When the soil of a site is
homogeneous, the infiltration characteristics of its surface layer depend on the ve

cover and human activity. The purpose of this study is to determine the hydro-physical
properties which affect infiltration into the soil surface layer at Snoubar Jableh Plantation
Site (Lattakia). This is in order to illustrate the impact of vegetal cover and human activity
on infiltration characteristics of soil. For this purpose, 20 field infiltration experiments
using a single ring were conducted on patches of coniferous and broad-leaved trees. The
results indicate that the soil has good infiltration characteristics, except in the oak plot
which showed low Ks in comparison with other species plots due to soil compaction and
human activity. The results also indicate that the decomposed organic material layer under
conifers protect soil against compacting and improve infiltration characteristics.
The current research aims to study the effect of chemical disinfectants
on the roughness and hardness of the surface of the cobalt chrome
alloy, where the use of cleansing Sodium hypochlorite 5.25%
and distilled water (the control sample), Been ma

samples and was doused with samples intravenously cleared, then it
was measured surface roughness using an Atomic force microscope, and
measuring the hardness of the surface using a Vickers measuring device
