Catalytic dehydroisomerization of n-alkanes to isoalkenes
An equilibrated mixture of pentene isomers was produced by dehydroisomerization of n-pentane on catalysts consisting of Pt clusters within [Fe]ZSM-5 channels. These catalysts showed high isomerization rates, excellent stability even without added H2, and isopentene selectivities above 60%. Metal sites on Pt clusters dehydrogenate n-alkanes and n-alkenes formed undergo skeletal rearrangements wi...
متن کاملHyperconjugation Is the Source of Helicity in Perfluorinated n-Alkanes.
Hyperconjugative, steric, and electrostatic effects were evaluated as possible sources of the helicity in linear perfluorinated alkanes through analysis of natural bond orbitals and classical electrostatics. Contrary to previous rationalizations, which indicate dominating steric or electrostatic effects, this analysis indicates that hyperconjugative stabilization through σCC →σ*CF interactions ...
متن کاملSubterminal oxidation of n-alkanes in achlorophyllous alga Prototheca sp.
Some Prototheca sp. are known to be involved in n-hexadecane degradation. Two derivatives derived from n-hexadecane in such Prototheca sp. were identified as 5-hexadecanone and 5-hexadecanol. n-Hexadecane was assumed to be converted to 5-hexadecanol and then to 5-hexadecanone through a unique subterminal oxidation pathway in such Prototheca sp.
متن کاملn-alkanes on MgO(100). II. Chain length dependence of kinetic desorption parameters for small n-alkanes.
Coverage-dependent desorption-kinetics parameters are obtained from high-quality temperature-programmed desorption data for seven small n-alkane molecules on MgO(100). The molecules, CNH2N+2 (N=1-4,6,8,10), were each studied for a set of 29 initial coverages at a heating ramp rate of 0.6 K/s as well as at a set of nine ramp rates in the range of 0.3-10.0 K/s. The inversion analysis method with ...
متن کاملTerahertz vibrational modes induced by heterogeneous nucleation in n-alkanes
0009-2614/$ see front matter 2010 Elsevier B.V. A doi:10.1016/j.cplett.2010.05.075 * Corresponding author. E-mail address: [email protected] (D.M. Mittleman) We describe the observation of a broad and strongly temperature-dependent peak in the terahertz absorption spectrum of several linear n-alkanes. On cooling from the liquid into the rotator phase, the absorption is enhanced within a very narr...
