Host-Guest Complexation of Perethylated Pillar[5]arene with Alkanes in the Crystal State.
Angewandte Chemie, 2015Activated perethylated pillar[5]arene crystals show an unexpected alkane-shape- and -length-selective gate-opening behavior. Activated crystals were obtained upon removing solvents from perethylated pillar[5]arene crystals by heating.

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,

A microporous metal-organic framework for gas-chromatographic separation of alkanes.
Angewandte Chemie, 2006A zinc-based metal-organic framework (MOF) can be transformed reversibly from an open (a) to a dense (b) configuration. The microporous solid is the first example of a MOF that is highly selective in the gas-chromatographic separation of alkanes.

Biodegradation of C7 and C8 iso-alkanes under methanogenic conditions.
Environmental Microbiology, 2015Iso-alkanes comprise a substantial proportion of petroleum and refined products that impact the environment, but their fate is cryptic under methanogenic conditions.

Phenolic compounds derived from lignin are important feedstocks for the sustainable production of alkane fuels with C6–C9 carbons. Hydrodeoxygenation (HDO) is the main chemical process to remove oxygen-containing functionalities.

Great efforts have been made to convert renewable biomass into transportation fuels. Herein, we report the novel properties of NbO(x)-based catalysts in the hydrodeoxygenation of furan-derived adducts to liquid alkanes.

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.

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).

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 ...
