Chemocatalysis of sugars to produce lactic acid derivatives on zeolitic imidazolate frameworks 2016 Access copy available to the general public Unrestricted Several research studies related to biorefining have focused on developing routes for biomass conversion into biomaterials or platform molecules. In this work, the zeolitic imidazolate frameworks (ZIFs) ZIF-8 and ZIF-67 have been tested as catalysts in the conversion of sugars (sucrose, glucose and fructose) into methyl lactate. ZIF-8 and ZIF-67 have the same sodalite type zeolite structure but behaved differently in the sugar conversion in methanol due to the respective presence of Zn and Co in their structures. ZIF-8 has been found to be the most active for the conversion of sugars into methyl lactate (yield 42%) and was reused in four catalytic cycles. The chemical and physical effects caused by these cycles on the catalysts have been studied by several techniques (X-ray diffraction, thermogravimetric analyses, infrared spectroscopy, X-ray photoelectron spectroscopy, scanning electronic microscopy and nitrogen adsorption). info:eu-repo/grantAgreement/ES/MINECO/MAT2013-40566-R info:eu-repo/grantAgreement/ES/DGA/T05 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 6.844 2016 ENGINEERING, CHEMICAL 5 / 135 = 0.037 2016 Q1 T1 CHEMISTRY, PHYSICAL 20 / 145 = 0.138 2016 Q1 T1 2.451 2016 Physical and Theoretical Chemistry 2016 Q1 Catalysis 2016 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion (orcid)0000-0002-9934-1707 Zornoza, B.
