o:3494 Catalytic activity of clinoptilolite-based catalysts in the esterification of levulinic acid en Abstract: Natural zeolite – clinoptilolite loaded with SnO2 (TOHCLI) or sulfated SnO2 (STOHCLI) was studied inthe esterification of levulinic acid (LA) with octanol and ethanol. TOHCLI showed a high activity (55 %) in the conversion of LA into octyllevulinate (OLA) and a moderate activity (22 %) in the conversion to ethyl levulinate (ELA). Total conversion of LA to OLA and ELA was achieved by STOHCLI which is explainedby the presence of Brönsted and Lewis acid sites in the STOHCLI. clinoptilolite, sulfated SnO2, levulinic acid, levulinate esters 1552100 978-86-916637-2-8 2023-12-08T11:20:37.548Z 44 no 46 Jelena Pavlovic Institute of Soil Science 0000-0001-9424-1080 46 Margarita Popova 46 Magdolna Mihalyi 46 Matjaz Mazaj 46 Gregor Mali 46 Janez Kovač 46 Hristina Lazarova 46 Nevenka Rajic application/pdf 2799130 https://unilib.phaidrabg.rs/o:3494 no yes 1 70 92000004 71A05 8th Serbian-Croatian-Slovenian Symposium on Zeolites 2019
