| Abstract: | Under microwave heating,crotonaldehyde oxime was synthesized in ethanol using croton aldehyde as the starting materials,and further dehydrated to crotonic nitrile.Effects of microwave output power,reaction time and amount of acetic anhydride on the reaction were examined.The optimal reaction conditions were:microwave output power of 540 W,reaction time of 45 s with the amount of acetic anhydride to be 10 times of crotonaldehyde oxime in mass.Under this condition,total yield of 87.3% and content of GC as high as 98.5% can be achieved. |
