Optimization of laboratory synthesis conditions for n-butyl acetate
N-butyl acetate was synthesizd with glacial acetic acid and anhydrous ethanol as raw materials,concentrated sulfuric acid as catalyst and anhydrous magnesium sulfate as desiccant.The effects of feeding ratio,reaction time and temperature,concentrated sulfuric acid dosage,detergent etc.on the yield and purity were studied.The optimal reaction conditions were as follows:the ratio of acetic acid to n-butanol was 1∶1.05,the amount of acetic acid was 14.00g,the dosage of concentrated sulfuric acid was 1.00mL,and the reflux reaction time was 40 minutes.Under these conditions,n-butyl acetate was synthesized with the purity of over 98%and the yield could reach more than 80%.
