Study on Ammonium Ferric Sulfate Dodecahydrate Catalytic Synthesis of N-butyl Acetate with Microwave Irradiation

N-butyl acetate was synthesized by using ammonium ferric sulfate dodecahydrate as catalyst with microwave irradiation method.The influences of the power of microwave radiation,reaction time,mole ratio of glacial acetic acid to n-butanol,a mount of catalyst and the water diversion on esterfication were discussed and the optimum processing condition was found.The optimum condition of the synthesis of n-butyl acetate which was decided by single-factor experiments as fowllows: power of microwave radiation 240 W,radiation time15 min,the amount of catalyst 1.3 g;mole ratio of glacial acetic acid to n-butanol 1.2:1.0,and yield 82.3%.The method was distinguished for it's virtues: short time,mild condition,simple post-pressing and good for environment.
