Sulfonated acrylate esters have been synthesized
by using renewable raw materials such as fatty alcohols
of Al-Ceder oil. Mixed fatty acids were isolated
from Al-Ceder oil by hydrolysis; both saturated and unsaturated
fatty acids were isolated from the mixed fatty
acids. The methyl esters of mixed fatty acid, saturated and
unsaturated acids of Al-Cedre oil were subjected to reduction
with (LiAlH4) to give the corresponding fatty alcohols.
The products of the reduction process were
saponified and the hydroxyl values were estimated to further
confirm the reduction occurrence. The acrylate esters
were synthesized by esterification of acrylic acid with fatty
alcohols of C16:0, C18:0, C18:1, and C18:2 mixed saturated,
mixed unsaturated and mixed fatty acids of Al-Cedre oil,
respectively. This esterification was followed by addition
of NaHSO3 to form bisulfite adducts. The structures of the
prepared surfactants were characterized by IR and 1HNMR
spectroscopy. A series of useful surface parameters, stability
towards acids and base hydrolysis and calcium stability
have been determined. |
