FORMATION OF MESOPOROUS ALUMINA AT ROOM TEMPERATURE VIA COMBINED UTILIZATION OF ACETIC ACID (AS AN ORGANIC MODIFIER) AND CETYL TRIMETHYL AMMONIUM BROMIDE (CTAB) AS A CATIONIC SURFACTANT HAS BEEN INVESTIGATED IN N-HEPTANE MEDIUM. THE REACTANTS MOLAR RATIO WAS ALUMINUM ISOPROPOXIDE:ACETIC ACID:WATER:CTAB:N-HEPTANE, AS 1:1:3:_X_:15, WHERE _X_ WAS 1 OR 3. THE CALCINED MATERIALS (AT 600 °C FOR 3 H) WERE CHARACTERIZED ... إقراء المزيد
