Abstract: Benzoin was synthesized under ultrasound irradiation using benzaldehyde as the raw material,dodecyl dimethyl benzyl ammonium bromide as phase transfer catalyst and VB1 as catalyst.The optimal reaction conditions were obtained by the use of orthogonal methods.When the quantity of benzaldehyde and VB1 was 0.1 mol and 0.09 g,respectively,the optimal reaction conditions were as follows:the quantity of phase transfer catalyst 0.02 g,reaction temperature 55 ℃,reaction time 30 min,and 2.5 mol/L NaOH solution was added to keep the pH value of solution at 8.8~9.3.The synthesis method was simple,high yield and good reproducibility.
