Versuchsvorschrift
In a stirred vessel, a mixture of 20 g of 3-(2'-methoxyethyl)-dihydro-2(3H)furanone, 100 g of acetic anhydride, and 10 of Nafion is heated to 120° C. Following a period of 69 h, the reaction is terminated (conversion: 100%) and the catalyst is separated by filtration. Following purification by distillation, there is obtained 61% of 3-(2'-acetoxyethyl)-dihydro-2(3H)furanone.
