Abstract

Eljárás nem kívánt szennyezések elválasztására (I) képletű 3-(2-acetoxi-etil)-dihidro-2(3H)-furanonból, azzal jellemezve, hogy előszörismert módon 3-(2-hidroxi-etil)-dihidro-2(3H)-furanon acetilezésével anem kívánt szennyeződéseket tartalmazó 3-(2-acetoxi-etil)-dihidro-2(3H)-furanont állítanak elő, majd a kapott termék erős ásványisavakkal történő kezelése után a nem kívánt szennyeződésekbomlástermékeit az (I) képletű vegyületből elválasztják.
