The structure of three kinds of ammoxidative lignosulfonate was studies by elementary analysis, GPC, FTIR and UV. The proper reaction mechanism based on investigation was provided. Results indicated that: molecular weights of products decreased; aromatic structure degraded partly; nitrogen contents increased and C/N ration decreased. Among three lignins (CaLs, SEP and CA), the nitrogen content of SFP increased, most N mainly exits in amine, amide and cyclic bonded nitrogen.
