Abstract

OSTOPEK ZA PRIPRAVO LEVULINSKE KISLINE, STABILNE PRI SKLADIŠČENJU. Postopek za pripravo barvno stabilne levulinske kisline z umiljenjem acetilsukcinatov z vodnimi mineralnimi kislinami, ki poteka tako, da izhodne produkte v reaktorski kaskadi kontinuirno protitočno obdelujemo z vodno paro, pri čemer izvedemo reakcijo nad vreliščem pri reakciji nastajajočega ali nad vreliščem nastajajočega vodnega azeotropa.
