2,5-Hexanedione is many times more potent than hexane, the parent compound, in causing neurotoxicity in experimental animals. It appears that the neurotoxicity of 2,5-hexanedione resides in its g-diketone structure since 2,3-, 2,4-hexanedione and 2,6-heptanedione are not neurotoxic, while 2...
The structure is shown below: Synthesis of Hexane Hexane is generally produced from naphtha, one of the lightest fractions obtained directly from petroleum refining. This fraction, which makes up about 20 per cent of the weight of crude oil, consists of a mixture of C5 to C10 hydrocarbons and...
Particularly, the role of non-elementary reactions was emphasized, indicating the need for refinement of the mechanisms based on new experimental data. Keywords: methylcyclohexane; fuel surrogate; flame structure; flame radicals; flame chemical speciation; molecular-beam mass spectrometry; kinetic mechanism...

Biosurfactants, as microbial bioproducts, have significant potential in the field of microbial enhanced oil recovery (MEOR). Biosurfactants are microbial bioproducts with the potential to reduce the interfacial tension (IFT) between crude oil and water,
structure of 32 semiflexible (mostly conjugated) polymers that differ drastically in aromatic backbone and alkyl side chain chemistry. An effective mobility value,ζ, is calculated using an assigned atomic mobility value within each repeat unit. The only adjustable parameter in the calculation ofζis...
Sphingolipids have limited solubility in many common solvents such as chloroform, hexane, ethyl ether, and even methanol. To overcome this insolubility problem, various solvent mixtures have been developed. One of the most universal sphingolipid solvents is a mixture of chloroform/methanol/water. Howe...
