Abstract

Sodium LIGNOSULPHONATE, soluble in water, was prepared from KRAFT LIGNIN, precipitated from black liquor, using Na2S205 or Na2S03 in a PLUG REACTOR at 6-7 atmospheres, pH=6.5 and 175 c°: Then, the FT-IR and UV spectra of the product were compared with the spectra of imported LIGNOSULPHONATE. Also, using GEL PERMEATION CHROMATOGRAPHY (GPC), the average molecular weights of the product and that of imported sample were compared and the results evaluated. It was confirmed that the sulphonation of KRAFT LIGNIN has occurred and the specifications of the product and those of the authentic sample are reasonably similar.
