Abstract
Viene descritto un procedimento per la decomposizione catalitica selettiva di eteri alchilici ed alcooli in una carica proveniente dalla sintesi del metil ter amil etere (TAME) che consiste nel far reagire detta carica in presenza di un catalizzatore costituito da silice modificata con l'aggiunta di allumina in quantità compresa fra lo 0,1 e l'1,5% in peso rispetto alla silice operando ad una temperatura compresa fra 200 e 250°C e ad una velocità spaziale (LHSV) compresa fra 4 e 15 h- 1.
