Versuchsvorschrift
In a stirred vessel there is heated to 120° C. a mixture of 20 g of 3-(2'-methoxyethyl)-dihydro-2(3H)furanone, 100 g of glacial acetic acid, and 10 g of Nafion. Following a period of 69 h, the reaction is terminated (conversion: 89%) and the catalyst is separated by filtration. Following purification by distillation, there is obtained 65% of 3-(2'-acetoxyethyl)-dihydro-2(3H)furanone (based on the 3-(2'-methoxyethyl)-dihydro-2(3H)furanone used).
