Isolation of the C9 and C10 isoprenoid carboxylic acids, the C12 to C18α,ω-dicarboxylic acids, and the 2-methyl 1,n-dicarboxylic acids (n is 13, 15, and 16) from organic extract of the Colorado Green River shale (Eocene) is reported. Separation was achieved by column and gas-liquid chromatographic techniques and structural identification of individual components, by mass spectrometry.
