The kinetics of the addition reaction of chloroacetic acid to oleic acid (c
hloroacetoxylation) in the presence of sulfuric acid as a catalyst were inv
estigated. The reactions were carried out at the same concentration of both
reactants at various temperatures and catalyst content. The reaction time
ranged from 30 min up to 12 h, and the reaction course was observed by dete
rmining mainly iodine value, and chlorine content of the oil samples at 30-
min intervals. The experimental data fitted the reversible second-first ord
er rate equation for bimolecular-unimolecular type reactions. The reaction
constants of the forward and reverse reactions were obtained at temperature
s 70 and 80 degrees C. The effect of sulfuric acid content on the reaction
constant was investigated at 70 and 80 degrees C.
