Synthesis of hydroxyfatty esters by sequential epoxidation-hydrogenolysis: Solvent effects 2021 Access copy available to the general public Unrestricted The tandem/sequential combination of epoxidation and hydrogenolysis for unsaturated fatty esters is not straightforward, due to incompatibility problems with the impurities present or generated in the used solvents. The chlorinated impurities in alpha, alpha, alpha-trifluorotoluene leads to the formation of important amounts of chlorohydrins by HCl formation in the hydrogenolysis step. The use of trifluoroethanol (TFE) in the epoxidation step produces trifluoroacetic acid traces by oxidation, responsible for the opening of the epoxide with water and TFE. The solvent of choice was finally isobutyl acetate, which gathers the required physicochemical properties, with 85 % yield of hydroxystearates from methyl oleate in a sequential process. info:eu-repo/grantAgreement/ES/DGA-ERDF/E37-20R info:eu-repo/grantAgreement/ES/MCIU/RTI2018-093431-B-I00 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 5.723 2021 ENVIRONMENTAL SCIENCES 77 / 279 = 0.276 2021 Q2 T1 CHEMISTRY, PHYSICAL 60 / 165 = 0.364 2021 Q2 T2 1.08 2021 Process Chemistry and Technology 2021 Q1 Catalysis 2021 Q1 9.8 2021 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Herrerias, C.
