| Abstract: | The reaction conditions and reaction mechanism were studied on synthesis of isopropyl chloride from isopropanol and hydrochloric acid catalyzed by zinc chloride. The results showed that the yield of isopropyl chloride is 81.6% under the optimum reaction conditions. From the experimental results, we obtained the kinetic equation: r=k［ZnCl2］2.8［HCl］［(CH3)2CHOH］. The apparent activation energy is 72.31 kJ/mol and the active component of the catalyst may be ［(Zn2Cl5)-*(H3O)+］. The coexistence of SN1 and SN2 type reactions was proposed. |
