SBA-15 Modified with Tethered Ionic Liquids Applied in the Esterification of Valeric Acid with Pentanol—Towards Cellulosic Biofuels
|Title:||SBA-15 Modified with Tethered Ionic Liquids Applied in the Esterification of Valeric Acid with Pentanol—Towards Cellulosic Biofuels||Authors:||Mullins, Lisa; Sullivan, James A.||Permanent link:||http://hdl.handle.net/10197/12277||Date:||5-Sep-2020||Online since:||2021-06-21T16:06:48Z||Abstract:||Two catalysts are prepared by tethering ionic liquid cation components (1-(propyl-3-sulfonate)-3-(3-trimethoxysilylpropyl) imidazolium) with either chloride or sulphate anions, to the surface of a mesoporous SiO2 material through a condensation reaction. These are characterized using elemental analysis, TGA-MS, FTIR (and D-FTIR), TEM, physisorption and NH3 adsorption (TPD and FTIR), and applied in the valeric acid + pentanol esterification reaction to form the sustainable biodiesel Pentyl Valerate. The material containing the sulfate counter-ion was significantly more active than the chloride analogue.||Type of material:||Journal Article||Publisher:||MDPI||Journal:||Sustainable Chemistry||Volume:||1||Issue:||2||Start page:||138||End page:||153||Copyright (published version):||2020 the Authors||Keywords:||Green catalysts; Biorefinery; Calaytic conversions; Cellulose; Biofuels||DOI:||10.3390/suschem1020011||Language:||en||Status of Item:||Peer reviewed||This item is made available under a Creative Commons License:||https://creativecommons.org/licenses/by/3.0/ie/|
