In this thesis continues synthesis of Ethylene glycol diacetate and Ethylene glycol monoacetate is performed by Ethylene glycol, acetic acid and the Amberlist 36 catalyst bed. The products are detected and measured by the three methods of GC-MS, GC-FID and FT-IR.The effects of different variables on synthesized products including Temperature, Mole ratio of Acetic Acid to Ethylene glycol, the Weight of Catalyst and Volume rate are analyzed through experimental design. Optimum values for Temperature, Mole ratio of Acetic Acid To Ethylene glycol, the Weight of catalyst and Volume rate are (T:90°C, AA/EG:3, the weight of catalyst:3g, volume rate:0.3 ml/min) Respectively in these conditions, 100% percent of Ethylene glycol is converted to Ethylene glycol diacetate. Optimum values of Temperature, Mole ratio, Weight of catalyst and Volume rate for 97 percent of Ethylene glycol converted to ethylene glycol monoacetate, are (T:77.5°C, AA/EG:1.125, the weight of catalyst:2.1g, volume rate:0.5 ml/min respectively. Also discontinuously system equipped with Azeotrope distillation for purification of Ethylene glycol from waste of factories are used for providing initial materials.
