| Abstract | ||
| 4-Stearoylresorcinol was prepared by acylation of resorcinol with stearoyl chloride in the presence of zinc chloride as catalyst in a batch reactor. The temperature range of reaction was (50-80)C. The rate of acylation increased with temperature up to (70 C). The conversion of reactants appeared to follow second order kinetic model. The reaction rate constant was (0.0031 l/mol.min) and was higher at higher temperatures. Activation energy was (16.8258 kJ/mol). The optimal catalyst concentration was (2.9936 mol/l). Also, a quantitative relationship was derived to represent the weight of the product as a function to the reaction variables. The quantitative relationship gave mean deviation equal to (5%). The product concentration was measured by UV spectroscopy. Keywords: - kinetic, Friedel-Craft reaction, photo-stabilizer, batch reactor. | ||
