Abstract:

The present invention relates to modified lignosulfonate materials and the process for their preparation. These modified lignosulfonates result from the sulfonation of ultrafiltered lignosulfonates by reaction with sulfite-bisulfite salts. The removal of sugars and other low molecular weight impurities makes formation of these new modified lignosulfonates more complete. These derivative materials when reacted with metal salts such as chromium, ferrous, ferric, titanium, and zirconium produce oil well drilling fluid dispersant products with significantly improved performance and thermal properties.
