Its production via heterogeneous catalysis is crucial for avoiding important product losses typically found in the aqueous work-up in homogeneous catalysis. In this work, we present a study of the catalytic synthesis of solketal using sulfonated hydrothermal carbons (SHTC). They were prepared from glucose and cellulose resulting in different textural properties depending on the hydrothermal treatment conditions. The sulfonated hydrothermal carbons were also coated on a graphite microfiber felt (SHTC@GF). Thus, up to nine different solids were tested, and their activity was compared with commercial acidic resins. The solids presented very different catalytic activity, which did not correlate with their physical-chemical properties indicating that other aspects likely influence the transport of reactants and products to the catalytic surface. Additionally, the SHTC prepared from cellulose showed better reusability in batch reaction tests. This work also presents the first results for the production of solketal in a flow reactor, which opens the way to the use of SHTC. info:eu-repo/grantAgreement/ES/DGA/E37-17R info:eu-repo/grantAgreement/ES/MICINN/RTI2018-093431-B-100 info:eu-repo/grantAgreement/ES/MINECO-FEDER/ENE2016-79282-C5-1-R info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 3.52 2019 CHEMISTRY, PHYSICAL 65 / 158 = 0.411 2019 Q2 T2 0.722 2019 Physical and Theoretical Chemistry 2019 Q2 Catalysis 2019 Q3 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion (orcid)0000-0002-0136-5138 Fraile, José María Universidad de Zaragoza García-Bordejé, Enrique (orcid)0000-0002-2676-8814 Pires, Elísabet Universidad de Zaragoza 2013 765 Universidad de Zaragoza Dpto.
