Abstract
The chemical structure of two acid hydrolysed soil humic acids was investigated
using analytical pyrolysis. A large part of the pyrolysis mixture consisted
of a homologous series of straight chain alkanes, alk-1-enes and a, u -
alkadienes probably derived from plant cuticles. The origin of other major
components in the pyrolysate, phenols and aromatic hydrocarbons, is less clear. | 5 pages, 1 figure, 1 table, 8 references.
