AbstractWe demonstrated two NAD+‐linked alcohol dehydrogenases in cell free extracts ofCandida tropicalis grown onn‐tetradecane. Comparative studies of localization, properties and regulation indicate that these enzymes are involved in two different pathways ofn‐alkane metabolism, one cytoplasmic and the other mitochondrial. Kinetic properties, such as

Penetration of alkane molecules into the adsorbed film gives rise to a surface freezing transition of cationic surfactant at the alkane-water interface. To examine the effect of the alkane chain length and counterion on the surface freezing, we employed ...

The chlamydospores of Ustilago maydis , U. nuda , and Sphacelotheca reiliana were analyzed by gas chromatography and mass spectrometry for their hydrocarbon contents. For the first time we observed that they contain paraffinic hydrocarbons; the average contents were 42,

Effect of Chain Length and Pore Accessibility on Alkane Adsorption in Kerogen
, 2015Configurational-biased Grand Canonical Monte Carlo and Molecular Dynamics simulations were used to investigate the adsorption and structure of n-alkanes in realistic models of kerogen (the organic phase in gas shales).

Alkane activation on crystalline metal oxide surfaces.
Chemical Society Reviews, 2014Advances in the fundamental understanding of alkane activation on oxide surfaces are essential for developing new catalysts that efficiently and selectively promote chemical transformations of alkanes.

Volume changes on mixing normal alkanes with branched alkanes
Journal of Chemical & Engineering Data, 1977Table 1. Excess Volumes, 6, at 25 O C where xi is the mole fraction of component i and ni is its chain length. The principle has been extended with some success to other homologous series (2) and has been found applicable to gaseous mixtures as well (3, 7).

The selective oxidation of hydrocarbons from oil, coal and natural gas has been an important problem for many years. This problem has now become particularly pressing and urgent due to the need for a much more economical use of natural raw materials as well as the need to resolve ecological problems, the minimizing of side reaction products. E.g.

Über Alkoxymethyl‐disulfon‐alkane
Archiv der Pharmazie, 1972AbstractDie Carbanionen von 1,1‐Disulfon‐äthanen (1a, 1b) oder Halogen‐disulfon‐methanen (1e) reagieren mit α‐Halogenäthern unter Bildung von 1‐Alkoxy‐2,2‐disulfon‐propanen (3a, 3b) bzw. 1‐Halogen‐1,1‐disulfon‐2‐alkoxy‐äthanen (3e). Aus Diäthylsulfon‐methan und Chlormethyläther entsteht 1,3‐Bismethoxy‐2,2‐bisäthylsulfon‐propan (6b).1‐Alkoxy‐2,2 ...

The hydrogen-hydrogen (H-H) bond or hydrogen-hydrogen bonding is formed by the interaction between a pair of identical or similar hydrogen atoms that are close to electrical neutrality and it yields a stabilizing contribution to the overall molecular ...
