Abstract

Abstract: Abundant natural renewable resource, α-pinene, has been transformed into a reaction mixture containing about 60% its dimers and 40% its isomers via dimerization/isomerization over a novel Brönsted-Lewis double acidic heteropoly inorganic-organic salt, Mn0.5 [MIMPS]2 PW12 O40 . The reaction mixture can be treated as a biomass high energy density fuel with a density of 0.90 g/mL (20 °C), a freezing point of −66 °C, a viscosity of 26.5 mm 2 /s (−10 °C) and a heat value of 39.7 MJ/L. The solid catalyst, Mn0.5 [MIMPS]2 PW12 O40, has been synthesized via the replacement of protons in neat phosphotungstic acid by both metal cations Mn 2+ and organic intermediate 3-(N-methylimidazole) propane sulfonates (MIMPS), and characterized by Fourier-transform infrared and pyridine adsorption Fourier-transform infrared spectroscopy, X-Ray Diffraction, Thermal-gravity Analysis, Brunauer-Emmett-Teller (BET) surface area analysis, Inductively Coupled Plasma Atomic Emission Spectroscopy and potentiometric titration technology. In addition, easy recovery and steady reusability of this catalyst have been demonstrated by an eight-run recycling test. Graphical abstract: Image Highlights: Heteropoly inorganic-organic salt Mn0.5 [MIMPS]2 PW12 O40 was reported. Transformation of α-pinene toward HEDF was achieved by Mn0.5 [MIMPS]2 PW12 O40 . Easy recovery and steady reusability of Mn0.5 [MIMPS]2 PW12 O40 were demonstrated.
