The structure-adsorption behavior-dispersion property relationship plays a key role in designing a dispersant or surfactant, such as a coal-water dispersant and a water-reducing agent. In this work, was classified into three fractions with narrow mol. weight distributions via the ultrafiltration method. The adsorption behavior of these three fractions was tested via a quartz crystal microbalance with dissipation monitoring, which showed that the adsorption amounts of the three fractions were far higher than that of sulfomethylated lignin. Fraction-1, with the lowest mol. weight, exhibited the greatest adsorption amount on a Au surface under salt-free conditions. This result illustrates that the alkyl chain is more effective for dispersants with low mol. weight to improve its adsorption amount Fraction-3, with the highest mol. weight, exhibited the greatest adsorption amount on a Au surface under salt-added conditions. This result further illustrates that both the alkyl chain and salt are pos. factors for improving the adsorption amount of dispersants. More importantly, the dispersion stabilization of the TiO2 slurry was significantly improved using the alkAL-S fractions, especially Fraction-3. Based on these results, the alkyl chain crosslinked of lignosulfonate is a promising approach for the industrial applications of lignin as an applicable dispersant.1,6-Dibromohexane(cas: 629-03-8Electric Literature of C6H12Br2) was used in this study.
1,6-Dibromohexane(cas: 629-03-8) is generally used to introduce C6 spacer in the molecular architecture. Some of the examples are: synthesis of pyrrolo-tetrathiafulvalene molecular bridge (6PTTF6) to study redox switching behavior of single molecules; synthesis of water-soluble thermoresponsive polylactides.Electric Literature of C6H12Br2
