Abstract

Způsob výroby anhydridu kyseliny metyljantarové katalytickou hydrogenací kyseliny itakonové. Proces se vyznačuje použitím katalyzátoru Pd na uhlí a jako rozpouštědla se užívá acetanhydridu. Po odfiltrování katalyzátoru se získává surový produkt po prostém vakuovém zahuštění. Řešení se dotý­ ká výroby meziproduktů pro syntézu léčiv, polymerů, pryskyřic a povrchové aktivních látek.
