Sodium hexadecyl sulfate

Weil et al. [58] studied the hydrolysis of sodium hexadecyl ether (1 PrO) and octadecyl ether (1 PrO) sulfates in comparison to sodium octadecyl ether (1 EO) sulfate and sodium hexadecyl sulfate, and determined the kinetic constant ( j) for the first-order equation ... [Pg.233]

The hydrolysis of 0.05 N surfactant solutions was carried out in 0.05 N HC1 solution at 80°C. These constants demonstrate that propoxylated sulfates are less stable than those ethoxylated and all them less stable than alcohol sulfates. The time for 50% hydrolysis was 92 min for sodium hexadecyl ether (1 PrO) sulfate, 98 min for sodium octadecyl ether (1 PrO) sulfate, 136 min for sodium octadecyl ether (1 EO) sulfate, and 187 min for sodium hexadecyl sulfate... [Pg.233]

Photochemical monomerisation of the cyclobutane dimers (145) can be brought about effectively using tetra-O-acylriboflavins as the sensitiser. The reaction is efficient when carried out in aqueous solution with surfactants such as sodium dodecyl sulfate and sodium hexadecyl sulfate. A review has highlighted the many methods available for the photocleavage of nucleic acids. ... [Pg.92]

The emulsion copolymerization of VAc/BuA monomer system can be performed by other emulsion pol3mrierization methods, mini-emulsion and micro-emulsion polymerizations. When the mini-emulsion copol5nnerization carries out with the 50/50 molar ratio of VAc/BuA in the presence of sodium hexadecyl sulfate emulsifier, hexadecane co-surfactant and ammonium persulfate initiator, the results of this polymerization conducted in a batch process are different from that of conventional batch polymerization of this monomer couple [94]. For the mini-emulsion polymerization the polymerization rate is slowed done. [Pg.61]

Because of their proclivity to associate in solution, it is to be expected that surfactants and polymers can influence each other s solubility. There is abundant evidence of the ability of a surfactant to increase the range of solubility of polymers in water (see the next section). Less well known is the ability of a water-soluble polymer to increase the solubility range of a surfactant Schwuger and Lange (103), for example, reported that polyvinylpyrrolidone can reduce the Krafft point of sodium hexadecyl sulfate by close to 10°C—an effect evidently linked to a lowering of the monomer concentration required for aggregation in the presence of this polymer. [Pg.223]
