The title compound, C25H24ClN3, comprises a 2-imino-pyridine ring fused with a cyclo-octane ring, which adopts a twist boat-chair conformation. In the crystal, C-H⋯N inter-actions form R 2 (2)(14) ring motifs and mol-ecules are further connected by weak C-H⋯π inter-actions. The resulting supra-molecular structure is a two-dimensional framework parallel to the ab plane.

In the present work, renewable oxygenates 2,5-dimethylfuran (DMF) and dimethyl ether (DME) are considered as alternatives to fossil fuels for gasoline engines. The effects of blending DMF DME on combustion surrogate numerically studied. is toluene primary reference fuel (TPRF) mixtures containing iso-octane, n-heptane, toluene. Two skeletal mechanisms proposed analysis: mechanism A with 504 spe...

The number of annually registered internal-combustion vehicles still exceeds electric-driven ones in most regions, e.g., Germany. Ambitious goals are disclosed with the European Green Deal, which calls for new technical approaches and greenhouse gas neutral transition technologies. Such bridging technologies synthetic fuels transportation sector, using bioliq® process a CO2-neutral gasoline sup...

In the paper the problem of estimating the octane number of powerformed gasoline produced in a refinery is addressed. The model is designed in order to replace the existing measurement device during maintenance operation guaranteeing the continuity of product quality monitoring and control. Linear and nonlinear Moving Average models based on MLP neural networks have been designed to take into a...

Confinement breaks the translational symmetry of materials, making all thermodynamic and kinetic quantities functions of position. Such symmetry breaking can be used to obtain configurations that are not otherwise accessible in the bulk. Here, we use computer simulations to explore the effect of substrate-liquid interactions on thermodynamic and kinetic anisotropies induced by a solid substrate...

We have studied the phase diagrams of brine/oil/AOT mixtures m which the oils are mixtures of octane and tetradecane and the amount of AOT is small In addition, the properties of the AOT monolayer at the brine/oft interface as a function of the volume fraction # of tetradecane in the oil have been measured. The values of the interfacial tension and the phase diagram behaviour show that the Equi...
