Sodium dodecylbenzene sulfonate SDBS

From an analytical point of view, the use of anionic surfactants as enhancers of CL reactions is most limited. One of the most recent examples is the use of sodium dodecylbenzene sulfonate (SDBS) as a CL enhancer of the system Ru(hpy) - SO - KBr03 (bpy = 2,2 -bipyridyl) [60], The authors of this work propose the following mechanism for the chemiluminescent system ... 

The general procedure for dispersion involves use of sonication, which causes an unzipping mechanism of dispersion as proposed by Smalley and co-workers [51]. Typical surfactants used for this purpose are sodium dodecylsulfate (SDS) or sodium dodecylbenzene sulfonate (SDBS). The latter shows a stronger interaction as a result of the presence of the aromatic ring. It also appears that longer and more branched hydrocarbon chains interact more efficiently [52],... 

The synthetic detergents industry originated in the 1940s, when it was found that a new anionic surfactant type—alkylbenzene sulfonate—had detergent characteristics superior to those of natural soaps. The first surfactant of this kind was sodium dodecylbenzene sulfonate (SDBS). This material was produced by the Friedel-Crafts alkylation reaction of benzene with propylene tetramer (a mixture of Co olefin isomers), followed by sulfonation with oleum or sulfur trioxide and then neutralization, usually with sodium hydroxide. The alkylation was typically performed using homogenous acid catalysts, such as HF or sulfuric acid. 

Experimental Materials and Procedure The equilibrium adsorption of sodium dodecylbenzene sulfonate (SDBS), and deoiled TRS 10-410 (a commercial petroleum sulfonate with an equivalent weight of 418) on silica gel (Davison Grade 62), and crushed Berea sandstone was measured at 30°C at two brine concentrations (0 and 1 wt.% NaCl). 

Moreover, catalytic asymmetric ring-opening reactions of meso-epoxides with aromatic amines also proceeded in the presence of a catalytic amount of bismuth triflate (Bi(OTf)3), chiral bipyridine ligand 7, and sodium dodecylbenzene sulfonate (SDBS) in pure water. The corresponding /3 -amino alcohols were obtained in good yields with high enantioselectivities (Scheme 3.57). ... 

In this respect, many single-chained surfactants have been investigated, including sodium alkyl- or aryl-sulfates [sodium dodecyl sulfate (SDS), sodium benzyl sulfate (SBS) and sodium dodecylbenzene sulfonate (SDBS), quaternary...
