Pyrolysis of soil humic acid yields a variety of products arising from heterogeneous materials associated to the humic structure and from this self. After acid hydrolysis most of the compounds related to proteins, polysaccharides and lignin dissappear. Adsorbed compounds such as fatty and dicarboxylic acids are released after methylation and subsequent pyrolysis. In addition pyrolysis produces aromatic and substituted aromatic hydrocarbons. All the identified pyrolysis products have also been isolated by different complex and time‐consuming chemical degradations and solvent extraction procedures. Pyrolysis provide some evidence of the humic acid structure.
