Abstract:
     A process for preparing surfactant, alkylated lignosulfonate, from lignosulfonate includes regulating the pH valve of lignosulfonate solution to 10-12, adding C8-C16 straight-chain haloalkane, sealing, heating to 130-170 deg.C and reaction for 1-3 hr. Said surfactant features better amphipathy, and high surface activity.
