METHOD FOR SEPARATING CONTAMINANTS FROM 3-(2'-ACETOXY-ETHYL)-DIHYDRO-2(3H)FURANONE

A process for removing impurities from 3-(2'-acetoxyethyl)-dihydro-2(3H)-furanone (I), which comprises initially preparing the 3-(2'-acetoxyethyl)-dihydro-2(3H)-furanone containing the undesirable impurities in a manner known per se by acetylating 3-(2'-hydroxylethyl)-dihydro-2(3H)-fu...

Zusammenfassung:A process for removing impurities from 3-(2'-acetoxyethyl)-dihydro-2(3H)-furanone (I), which comprises initially preparing the 3-(2'-acetoxyethyl)-dihydro-2(3H)-furanone containing the undesirable impurities in a manner known per se by acetylating 3-(2'-hydroxylethyl)-dihydro-2(3H)-furanone, subsequently treating it with strong mineral acids and finally removing the decomposition products of the undesirable impurities from I.
