In the presence of rat liver microsomes and NADPH n-loctene, n-4-octene and 3-ethyl-2-pentene were converted to the glycols with no trace of epoxides. Increased substitution of ethylenic hydxogen atoms by alkyl groups was found to retard. the rate of biological oxid.ation but to enhance that of epoxidation by perbenzoic acid. in chloroform. Microsomes without cofactors hydrolyzed the monosubsti...
In the context of the search for gasoline surrogates for kinetic modeling purpose, this paper describes a new model for the low-temperature auto-ignition of n-heptane/iso-octane/hexene/toluene blends for the different linear isomers of hexene. The model simulates satisfactory experimental results obtained in a rapid compression machine for temperatures ranging from 650 to 850 K in the case of b...
The autoignition kinetics of hydrocarbons is an important criterion for selecting fuels piston reciprocating engines, and it can be determined by relative performance to mixtures alkanes, n-heptane iso-octane, under certain standardized operating conditions. 2-methylfuran a potential biofuel candidate, whose chemistry markedly different from alkanes. Its octane behavior when blended with paraff...
In this study, the dependence of minimum ignition energies (MIE) on geometry, source radius and mixture composition is investigated numerically for methane/air iso-octane/air mixtures. Methane iso-octane are both important hydrocarbon fuels, but differ strongly with respect to their Lewis numbers. Lean air mixtures have particularly large The results show that within flammability limits, MIE st...
The title compound, C(9)H(14)N(2)O, exists in the zwitterionic form in the crystal. The cyclo-octane ring adopts a twisted boat-chair conformation. In the crystal, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into sheets lying parallel to bc. The structure is also stabilized by π-π inter-actions, with a centroid-to-centroid distance of 3.5684 (8) Å.
