Bastow T.P.; Singh R.K.; van Aarssen B.G.K.; Alexander R.; Kagi R.I. (2001)2-Methylretene has been synthesised, characterised and identified in sedimentary material from a range of locations, source types and ages. 2-Methylretene was observed only in samples of Permian to Tertiary age and can be ...

Barber C.J.; Bastow T.P.; Grice K.; Alexander R.; Kagi R.I. (2001)Cyclodextrin GC stationary phases, well documented for their superior isomeric separation capabilities, have been investigated in the separation of crocetane (2,6,11,15-tetramethylhexadecane) and phytane (2,6,10,14-tetra ...

Joll C.A.; Couton D.; Heitz A.; Kagi R.I. (2004)A range of tetramethylammonium salts with different base strengths was compared for off-line thermochemolysis of an aquatic natural organic matter sample. Tetramethylammonium acetate (TMAAc) in methanol produced a different ...

Ellis L.; Singh R.K.; Alexander R.; Kagi R.I. (1996)Seven alkylaromatic hydrocarbons with an isohexyl and a methyl substituent group on adjacent ring carbons have been identified in a suite of crude oils derived from a range of locations, source types, palaeoenvironments, ...

Ellis L.; Singh R.K.; Alexander R.; Kagi R.I. (1995)Heating ortho-undecyltoluene with an acidic clay catalyst and hexamethylbenzene as a methylating agent resulted in the formation of hydrocarbon mixtures containing undecyltoluenes and dimethylundecylbenzenes. At short ...

Bastow T.P.; Van Aarssen B.G.K.; Chidlow G.E.; Alexander R.; Kagi R.I. (2003)A rapid small-scale method for the quantitative analysis of alkylphenols, alkylcarbazoles and benzocarbazoles from sedimentary matter is described using silica gel liquid chromatography and GC–MS techniques. Alkylphenol, ...

Bastow T.P.; van Aarssen B.G.K.; Herman R.; Alexander R.; Kagi R.I. (2003)Alkylphenols in crude oils can be affected by oxidation during storage. A crude oil and an alkylphenol mixture were exposed to light and air for various time periods, resulting in significant alterations of the alkylphenol ...
