In this thesis, the synthesis of ethylene glycol diacetate at pilot scale was performed by using industrial ethylene glycol and industrial acetic acid and levatite as catalyst. Products were identified and determined by using FT-IR and GC-FID techniques. In this thesis, the effects of molar ratio and catalyst type were studied. The optimal conditions for the molar ratio, 5 to 1 acetic acid to ethylene glycol and levatit catalyst were obtained at 30 g and a flow rate of 6.75 ml.min -1 . Ethylene glycol diacetate synthesized with 99% selectivity was used as oxygenated fuel additive in Euro 4 petrol and gasoline with ratios of 3% and 5% by weight, respectively. The results showed that this fuel additive reduced 60% of gasoline smoke opacity and 30% and 20% respectively of CO and unburned hydrocarbons (HC) from Euro 4 petrol smoke.
