Reaction Conditions:
with triethylamine in acetone at 20; for 24 h;
Steps:
6 Example 1
General procedure: Take 1mmol of furfuryl alcohol, 10mL of acetone, 100mg of Ru-WOx/HZSM-5 catalyst, and 2mmol of triethylamine into a 50mL three-necked flask. Slowly add 5mL of acetone solvent containing 1.5mmol of acetic anhydride at room temperature. After the addition is complete,Stir for 24 hours. After the reaction was completed, it was cooled to room temperature, and 30 mL of water was added. The aqueous layer was extracted with CH2Cl2 (3×10 mL).The organic layer was washed with brine, dried over anhydrous Na2SO4, filtered,The solvent was concentrated to obtain furfuryl acetate with a yield of 80%.The yield is quantified by NMR,The specific method is as follows: Take a certain amount of sample (~5mg) and add it to the NMR tube,Add quantitative (~5mg) cyclohexene as an internal standard, add 0.6ml deuterated chloroform,Perform nuclear magnetic inspection,Take three samples in parallel and take the average value to determine the yield.Furfuryl acetateThe hydrogen NMR spectrum is shown in Figure 1.
