Conversion of sugars to methyl lactate with exfoliated layered stannosilicate UZAR-S4 2020 Access copy available to the general public Unrestricted Biomass has been shown as an alternative to fossil fuels for obtaining chemicals. In this work, the transformation of sugars into methyl lactate (ML) at 160 °C was carried out using the layered stannosilicate UZAR-S3 (University of Zaragoza-solid number 3) and the delaminated material UZAR-S4 (University of Zaragoza-solid number 4) obtained from its exfoliation. The exfoliation of UZAR-S3 to UZAR-S4 increased the accessibility of the compounds to the catalytic sites and the medium-strength acidity. Thus, the yield to ML for sucrose transformation increased from 8% for UZAR-S3 to 49.9 % for UZAR-S4. In the reusability tests, the UZAR-S4 catalyst was characterized before and after reaction by several techniques such as X-ray diffraction, thermogravimetry analysis, scanning electronic microscopy, energy dispersive X-ray spectroscopy and nitrogen adsorption. A deactivation of the catalyst was observed, which was related to carbonaceous deposits that decreased the specific surface area and the pore volume of the catalyst. info:eu-repo/grantAgreement/ES/DGA-FSE/T43-17R info:eu-repo/grantAgreement/ES/MINECO-FEDER/MAT2016-77290-R info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 6.766 2020 CHEMISTRY, APPLIED 10 / 74 = 0.135 2020 Q1 T1 ENGINEERING, CHEMICAL 19 / 143 = 0.133 2020 Q1 T1 CHEMISTRY, PHYSICAL 36 / 162 = 0.222 2020 Q1 T1 1.397 2020 Chemistry (miscellaneous) 2020 Q1 Catalysis 2020 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion de la Iglesia, Ó.
