Abstract
A new synthesis method of D/L-ethyl mandelate is introduced.In this method D/L-ethyl mandelate was synthesized using mandelonitrile,absolute alcohol and concentrated sulfuric acid by means of alcoholysis.Ethyl mandelate's product was obtained from reaction feed liquid through neutralize reaction,desalting,recycle alcohol,washing,drying and rectification.In combination with experimental result this text analyzes and discusses influences factors of D/L-ethyl mandelate's quality and yield.These influences factors include reaction temperature,the mass ratio of mandelonitrile and absolute alcohol,crude product's quality before rectification and operating condition of rectification.
