Formation and reactions of alkyl adamantanes in sediments: Carbon surface reactions

Autor: Robert Alexander, Lyndon Berwick, Kieran Pierce

Publikováno v: Organic Geochemistry. 42:752-761

Diamondoids are hydrocarbons with a carbon skeleton that is superimposable on the diamond lattice. Adamantane is the cage-shaped primary unit of diamondoids and occurs widely in sediments and petroleum. The first report of adamantane isolated from pe

Single carbon surface reactions of 1-octadecene and 2,3,6-trimethylphenol on activated carbon: Implications for methane formation in sediments

Autor: Lyndon Berwick, Kieran Pierce, Robert Alexander

Publikováno v: Organic Geochemistry. 42:540-547

The reactions of a terminal alkene (1-octadecene) and a polymethyl phenol (2,3,6-trimethylphenol) on activated carbon have been investigated in closed system pyrolysis experiments in the temperature range 170–340 °C. The reaction products of 1-oct

Reprint of: Carbon catalysed hydrogen exchange in petroleum source rocks

Autor: Andrew Murray, Daniel Dawson, Robert Alexander, Kieran Pierce

Publikováno v: Organic Geochemistry. 41:130-134

Exchange of carbon bound hydrogen has been observed when alkenes, saturated and aromatic hydrocarbons are heated at moderate temperatures on carbonaceous surfaces (activated carbon and coal). Isomerisation of alkenes and the formation of hydrogenated

Structural identification and mass spectral interpretation of C3n highly branched alkanes in sediment and aquatic extracts and evidence for their anthropogenic origin

Autor: Paul F. Greenwood, Matthew J. Piggott, Nigel A. Lengkeek, Kieran Pierce

Publikováno v: Organic Geochemistry. 40:1055-1062

The structures of two distinctive series of C 3 n highly branched alkanes (HBAs), previously detected in sedimentary and aquatic extracts, were identified as polypropylene (PP) oligomers with different end groups, using gas chromatography (GC) and ma

Geosynthesis of dibenzothiophene and alkyl dibenzothiophenes in crude oils and sediments by carbon catalysis

Autor: Tahira Fazeelat, Muhammad Asif, Kieran Pierce, Robert Alexander

Publikováno v: Organic Geochemistry. 40:895-901

Sediment extracts and crude oils have been shown to contain methyl substituted biphenyls and dibenzothiophenes, with isomer distributions suggesting a geochemical relationship between the two compound classes. Laboratory simulation experiments have s
