WebbPhytane (2,6,10,14-tetramethylhexadecane, C 20 H42) is a C20 isoalkane with a boiling point near that of n-octadecane (C18H38). Both occur naturally in crude oil—they are … Webb1 sep. 2016 · The pristane/n-C 17 and phytane/n-C 18 ratios of the crude oil and extracted samples (Table 2) reflect that the oils and the extracts of Khatatba and Alam El Bueib source rocks are genetically related as they are derived from autochthonous organic matter deposited under reducing conditions in marine environments (Tissot and Welte 1984). Phytane is the isoprenoid alkane formed when phytol, a constituent of chlorophyll, loses its hydroxyl group. When phytol loses one carbon atom, it yields pristane. Other sources of phytane and pristane have also been proposed than phytol. Pristane and phytane are common constituents in petroleum and have been … Visa mer Phytane is a non-polar organic compound that is a clear and colorless liquid at room temperature. It is a head-to-tail linked regular isoprenoid with chemical formula C20H42. Phytane has Visa mer Pristane/Phytane ratio Pristane/phytane (Pr/Ph) is the ratio of abundances of pristane and phytane.
