Versuchsvorschrift
In a stirred vessel, a mixture of 10 g of 3-(2'-tert-butoxyethyl)-dihydro-2(3H)furanone, 50 g of glacial acetic acid, and 5 g of Nafion is heated to 120° C. Following a period of 19 h, the reaction is terminated (conversion: 100%) and the catalyst is separated by filtration. Following purification by distillation, there is obtained 98% of 3-(2'-acetoxyethyl)-dihydro-2(3H)furanone.
