Sodium naphthalene sulfonate

The fluid loss and thickening time characteristics of the cement slurry is altered, either by increasing the molecular weight of the lignin by cross-linking with formaldehyde or epichlorohydrin or by adding agents such as sodium sulfite, sodium metasilicate, sodium phosphate, and sodium naphthalene sulfonate. [Pg.46]

Figure 3.18 Change in electrical resistance of an anion exchange membrane (strongly basic anion exchange) with and without anionic polyelectrolyte layers in the presence of sodium tetradecyl sulfate (STS). 1. without the layers and with STS 2. with the layers (immersion time 4 h) and with STS 3. with the layers (immersion time 24 h) and with STS 4. with the layers and without STS 1 left vertical axis 2,3 and 4 right vertical axis. After an anion exchange membrane had been immersed in 100ppm anionic polyelectrolyte (polycondensation product of sodium naphthalene sulfonate and formaldehyde MW ca. 1000) solution for the respective time at room temperature, electrodialysis was carried out at a current density of 2.5 mAcmr2 using 0.10 N sodium chloride solution containing 2.16 X 10 3 mol dm3 of STS.

The formation of anionic polyelectrolyte layers on the surfaces of anion exchange membranes provides ionic cross-linkage and excess anionic charge on the membrane surfaces. Figure 5.25 shows the distribution of sulfur, based on sulfonate groups, for a cross-section of a membrane, measured by EPMA (Electron Probe Micro Analysis), when a strongly basic anion exchange membrane was immersed in an aqueous 200 ppm solution of the polycondensation product of sodium naphthalene sulfonate and formaldehyde for 17 h (sharp... [Pg.169]

Figure 5.26 Relationship of Pa50 to the concentration of 1 1 mixed salt solutions of sodium sulfate and sodium chloride using anion exchange membranes with and without anionic polyelectrolyte layers. (O) without the layer ( ) immersed in 1000ppm poly(styrene sulfonic acid) (reduced viscosity of 1.0% solution, r sp/C 0.714 dlg ) solution (X) with 1000ppm polycondensation product of sodium naphthalene sulfonate and formaldehyde (MW ca. 1000) solution. After an anion exchange membrane (NEOSEPTA AM-1 strongly basic anion exchange) had been immersed in the anionic polyelectrolyte solution for 17 h at 25.0 °C, 1 1 mixed salt solutions of sodium sulfate and sodium chloride were electrodialyzed for 60 min at 25.0 °C under vigorous agitation.
