Murchison C2球粒陨石的有机聚合物经碱性氧化铜氧化后，得到7种酚酸和多种非酚有机酸，包括大量的间羟基（3-羟基）苯甲酸和3-羟基-1，5-苯二甲酸。酚酸显然是从聚合物中的酚醚衍生而来，而酚醚又可能是由一氧化碳和氢在太阳星云中通过催化费托反应形成的。与此相反，陆地聚合物，如木质素，腐殖酸，和煤产量主要是对羟基（4-羟基）苯衍生物通过相同的氧化过程。
Seven phenolic acids and many nonphenolic organic acids, including large amounts of meta-hydroxy (3-hydroxy) benzoic acid and 3-hydroxy-1,5-benzene-dicarboxylic acid, were obtained from the organic polymer of the Murchison C2 chondrite upon oxidation with alkaline cupric oxide. The phenolic acids apparently were derived from phenolic ethers in the polymer, which in turn probably were formed from carbon monoxide and hydrogen by catalytic Fischer-Tropsch type reactions in the solar nebula. In contrast, terrestrial polymers such as lignin, humic acid, and coal yield mainly para-hydroxy (4-hydroxy) benzene derivatives by the same oxidation procedure.
