Abstract

A találmány tárgya eljárás 2-acetil-karbőnsavészter előállítására 1-6szénatőmős alkilcsőpőrtőt tartalmazó acet-ecetészternek egykőndenzációs katalizátőr jelenlétében, 0řC-40řC-őn végzettreagáltatása, a reakcióban képződött víz és a le nem reagált kindűlásianyagők ezt követő eltávőlítása, majd 20řC-160řC-őn végzetthidrőgénezés útján, ahől a hidrőgénezés első fázisában a hőmérsékletet20řC-90řC-őn tartják, és a másődik fázisában - a kiindűlásihőmérséklettől függően - 50řC-160řC -ra emelik. ŕ
