| 제목 | Determination of Kinetics Parameters for Gas-Phase Hydrolysis of AlCl3 |
| 초록 | In the present study, the kinetics of aluminum chloride (AlCl3) hydrolysis was studied in a batch reactor (500 ml stirring tank). The degree of hydrolysis reaction rates were determined through concentration measurement of a product gas, HCl, by using Ion Chromatograph (DIONEX, ICS-150). The H2O/AlCl3 molar ratio were varied from 1.5 (stoichiometric ratio) to 15, the reaction temperature from 150 to 210oC, and the AlCl3 concentration from 7.5×10-4 to 1.5×10-3 mol/L. The activation energy for early-stage hydrolysis were determined to be 88.1 KJ/mol from the experimental data and 72.2 KJ/mol by estimation using a molecular modeling program. The overall reaction rate was assumed to take the form as follow; -rHCl=(Ae-E/RT)CαAlCl3CH2O/1+k2CH2O The temporal variation of the product gas (HCl) concentration was calculated using the kinetic parameters in the literature. The four parameter, A, E, α, k2 were determined to be 1.85×109 L2.27/mol2.27s, 35.8 KJ/mol, 2.27, 833.7 L/mol respectively, to that fit experimental data. |
