英文摘要 | Tetraalkylammonium chloride is used for the phase transfer catalytic preparation of benzyl benzoate in a batch reactor from sodium benzoate in the aqueous phase and benzyl chloride dissolved in toluence as the organic phase. The effect of the structure of the catalysis is studied to avoid the formation of micelles and to increase the yield of the reaction. Experimental results show that at the later time of the batch preparation after an induction period the kinetics of the reaction can be described by a first-order reaction. The effect of the concentration of sodium benzoate and the cocatalytic effect of sodium iodide are discussed based on the experimental results. |
