Synthesis and fuel properties of high-energy density cyclopropanated monoterpenes

Biosynthesis of polycyclopropanated high energy biofuels

“…In fact, recent work on catalytic cyclopropanation of bioderived terpenes has led to excellent candidates for high-performance jet fuel blend stocks or specialized rocket propellant. 15 In this work, we designed POP molecules that can be used as high energy fuels. We explored the chemical diversity of microorganisms to identify and repurpose naturally occurring cyclopropanated molecules.…”

Thermal cyclodimerization of isoprene for the production of high-performance sustainable aviation fuel

“…1 H and 13 C NMR spectra were obtained as described previously. 22 Fuel characterization details (GC-FID, GC-MS, kinematic viscosity, density and heat of combustion measurements) are included in the ESI. †…”

“…21 The densities and volumetric NHOCs of terpenes can be further enhanced through cyclopropanation reactions. [22][23][24][25] Isoprene is a compelling substrate for the preparation of sustainable jet fuel blendstocks. It can be directly produced from biomass sugars via fermentation, 26 by dehydration of biosynthetic 3-methyl-3-buten-1-ol, 27 or from other bio-based substrates including mevalonolactone 28,29 and mesaconic/itaconic acid.…”

Thermal Degradation Products of <i>α</i>-Pinene in a Tubular Furnace in the Temperature Range from 300°C to 900°C: Contribution to Wildfire Flashovers

“…Bicyclic monoterpenes such as α-pinene possess high density of ~0.86 g•ml −1 [12], which doesn't change greatly with increasing temperatures [13]. Therefore, for example, when pyrolyzing plants in a wildfire emit α-pinene, its higher density relative to air allows it to migrate downwind at ground level and concentrate in nearby confined topographies such as canyons [14].…”
