Abstract
AbstractA medium soft pitch has been oxidized in oxygen at elevated temperature and pressure in the presence of strong alkali to yield a complex mixture of water‐soluble aliphatic acids and aromatic polycarboxylic acids in about 30% yield based on carbon. By chromatography of the methylated hydrocarbons obtained from the acids and from infra‐red spectra, it is concluded that these acids have mainly polynuclear structures.
