Abstract
Nella produzione di anidride maleica mediante ossidazione catalitica di butano in fase vapore la miscela di reazione viene formata da butano e da una corrente gassosa di riciclo, costituita da aria compressa e da gas esausto di ricupero dalla fase di assorbimento con solvente dell'anidride maleica prodotta, riciclo avente tenore di ossigeno e concentrazione di butano totale controllati.
