Synthesis of High-Stability Acidic β/Al-MCM-41 and the Catalytic Performance for the Esterification of Oleic Acid
With the increasingly serious in the energy shortage and environmental problems, biodiesel has been widely studied as a kind of non toxic fuel for renewable and easily biodegradable. Among all kinds of biodiesels, fatty acid ester, obtained from the esterification of oleic acid with alcohol, has received greater attention using as biofuel in recent years [1] [2]. This kind of biodiesel has the ...
متن کاملLysine-Grafted MCM-41 Silica as an Antibacterial Biomaterial
This paper proposes a facile strategy for the zwitterionization of bioceramics that is based on the direct incorporation of l-lysine amino acid via the ε-amino group onto mesoporous MCM-41 materials. Fourier transform infrared (FTIR) studies of lysine-grafted MCM-41 (MCM-LYS) simultaneously showed bands at 3080 and 1540 cm-1 and bands at 1625 and 1415 cm-1 corresponding to -NH3+/COO- pairs, whi...
متن کاملSulfunic Acid Modifired MCM-41 Mesoporous Silica as an Efficient Nano-Catalyst for Synthesis of amides and lactams from Oximes Via Beckman Rearrangement
Mesoporous MCM-41 silicas anchored with sulfonic acid (–SO3H) groups (denoted MSN-SA) via postsynthesis modification are very effective for the Beckman rearrangement. A simple and convenient procedure for conversion of a variety oximes to their corresponding amides and lactams has been developed. The reaction was carried out in the presence of MSN-SA as the catalyst. The best results for conver...

Application of Spherical Mesoporous Silica MCM-41 for Adsorption of Dibenzothiophene (A Sulfur Containing Compound) from Model Oil
Spherical mesoporous silica MCM-41 was synthesized for adsorptive removal of sulfur compounds from fossil fuels using 1mM solution of dibenzothiophene (DBT) in dodecane as model oil. The prepared silica adsorbent has been characterized by nitrogen adsorption-desorption analysis as well as Small Angle X-ray Scattering (SAXS), and transmission and Scanning Electron Microscopy (SEM) methods. R...
