Problem Statement
- Conventional methods for synthesizing ordered mesoporous aluminosilicates (OMAS) struggle to stabilize trivalent aluminum in the tetrahedral framework structure at high aluminum content.
- This limitation compromises the effectiveness of OMAS in various industrial applications lacking specific structural and textural properties.
- Existing synthesis approaches often result in OMAS materials with suboptimal catalytic activity in tertiary-butylation of phenol reaction.
- Existing methods lack uniformity and may not reliably yield OMAS materials suitable for specific industrial need, leading to inefficiencies and inconsistencies in material production.
- The presence of aluminum in less desirable coordination states hinders the performance of OMAS as solid acid catalysts, reducing selectivity and efficiency in catalytic reactions.
- Hence, there is a need for a standard synthesis process to produce OMAS consistently with desired properties.
Technology
The instant invention discloses an innovative Method: the “intrinsic hydrolysis method” for synthesizing ordered mesoporous alumino-silicates (OMAS), ensuring trivalent aluminum stability even at high content, without compromising the mesostructure, resulting in OMAS with superior structural and textural properties.
- The disclosed process involves dissolving aluminum nitrate and citric acid, adjusting pH, and adding absolute ethanol to obtain crystalline aluminum citrate. Sequential addition of precursors and hydrothermal treatment yields surfactant-free OMAS samples.
- The synthesized OMAS exhibit medium-to-strong Brønsted acidity & demonstrate excellent catalytic activity, particularly in the tertiary-butylation of phenol, with high selectivity towards specific products.
- This invention is extensively characterized using various analytical techniques such as XRD, TEM, SEM, MAS-NMR, XRF, and NH3-TPD to ensure quality and performance.
