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]

C. Among sodium salts, hexadecyl sulfate gave a maximum foam volume, above 700 cm3, at 75 °C while at 50°C the maximum corresponds to tetradecyl sulfate but, as expected, with a lower volume (around 550 cm3). The fact that solubility in water decreases as the chain length increases can explain the progressive displacement of the maximum to higher homologs as the temperature increases. [Pg.269]

As for the carboxylates, the remote site fragmentation Is much more pronounced with Increasing carbon chain length. For example, fragmentation Is seen for octyl sulfate but Is much more pronounced for longer-chained sulfates such as hexadecyl sulfate. [Pg.202]

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]
