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

The invention relates to a method for separating contaminants from 3-(2'-acetoxy-ethyl-dihydro-2(3H)furanone (I), whereby the 3-(2'-acetoxy-ethyl-dihydro-2(3H)furanone containing the undesired contaminants is first produced using known methods by acetylization of 3-(2'-hydroxy-ethyl-d...

Zusammenfassung:	The invention relates to a method for separating contaminants from 3-(2'-acetoxy-ethyl-dihydro-2(3H)furanone (I), whereby the 3-(2'-acetoxy-ethyl-dihydro-2(3H)furanone containing the undesired contaminants is first produced using known methods by acetylization of 3-(2'-hydroxy-ethyl-dihydro-2(3H)furanone and is subsequently treated with strong mineral acids. Finally, the decomposition products of the undesired contaminants of (I) are separated.
