Benzene eluate fractions from Chromatographic separations of extracts from carbonaceous chondrites and a few other samples have been examined for volatile organic components by high resolution capillary gas-liquid chromatography. A few meteorites give evidence for the presence of small amounts of aromatic hydrocarbons, but most show only traces. The amount present is apparently not directly related to the Wiik class nor to the amount of alkanes. However, when aromatic components are present, they are of relatively low molecular weight in Type I meteorites (Orgueil) and of somewhat higher molecular weight in Type II and III (Murray, Santa Cruz, Boriskino, and Mokoia). The benzene eluate fractions found in some meteorites are made up of large numbers of components, e.g. 60-140 in some cases, in relatively uniform concentrations. Compounds such as naphthalene, methylnaphthalene, biphenyl, acenaphthalene, acenaphthene, phenanthrene, and heavier components are apparently present.
