Reaction Conditions:

with phosphoric acid in dichloromethane;water at 120; for 1 h;Temperature;

Steps:

1.1

1) Put 32g of propionic anhydride into a 250mL three-necked flask, add 0.3g phosphoric acid and 0.3g polyphosphoric acid dropwise to 120°C, add 16.4g 2-methylfuran dropwise, continue the reaction at 120°C for 0.5 hours, add water after cooling down 100g and 100g of dichloromethane were stirred for 0.5 hours and then left to stand for liquid separation. Dichloromethane was distilled out under normal pressure and then distilled under reduced pressure to obtain 26.3g of 2-propionyl-5-methylfuran. The purity by GC was 99.0%. The rate is 95.3%.
