Lignosulfonates
Lignosulfonates, or sulfonated lignin are water-soluble anionic polyelectrolyte polymers: they are byproducts from the production of wood pulp using sulfite pulping. Most delignification in sulfite pulping involves acidic cleavage of ether bonds, which connect many of the constituents of lignin. The electrophilic carbocations produced during ether cleavage react with bisulfite ions (HSO3−) to give sulfonates. R-O-R' + H+ → R+ + R'OHR+ + HSO3− → R-SO3H
