Additional chain-branching pathways in the low-temperature oxidation of branched alkanes

Experimental confirmation of the low-temperature oxidation scheme of alkanes.

The Oxidation of Branched Chain Fatty Acids

It is noteworthy that while the majority of fatty acids occurring in nature belong to the normal series, those composed of more than twenty-two carbon atoms contain at least one tertiary carbon atom in their molecu1e.l The structure of these acids is entirely unknown. The problem of their structure naturally is identical with that of the location of t,he tertiary carbon atom. in the molecule. T...

comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.

heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...

The influence of branching efficiency on the rheology and morphology of melt state long chain branched polypropylene/polybutene-1 blends

In this study, the compatibility of the blends of polypropylene (PP) and polybutene-1(PB-1) homopolymer before and after long chain branching process were studied. The blends were prepared and long-chain branched directly via reactive extrusion process in presence of free radical initiator and trimethylolpropane tri methacrylate (TMPTMA) poly functional monomer. The optimum percentage of TMPTMA...

Revisiting the Kinetics and Thermodynamics of the Low-Temperature Oxidation Pathways of Alkanes: A Case Study of the Three Pentane Isomers.

This paper describes our developing understanding of low-temperature oxidation kinetics. We have investigated the ignition of the three pentane isomers in a rapid compression machine over a wide range of temperatures and pressures, including conditions of negative temperature coefficient behavior. The pentane isomers are small alkanes, yet have structures that are complex enough to allow for th...
