Usage

Chemical Properties

White crystalline powder

Uses

Sodium n-tridecyl sulfate acts as a foaming agent and a wetting agent. It is used as a cleaning agent and finds application in industrial and household cleaning products and personal care products. Further, it serves as an emulsifying agent in the transport of hydrocarbons. In addition to this, it acts as an anionic surfactant.

Preparation

To a three-necked flask equipped with a stirrer, dropping funnel, condenser, and drying tube, and containing 200 gm (1.0 mole) of tridecyl alcohol, is added dropwise 116.5 gm (1.0 mole) of chlorosulfonic acid at such a rate that the temperature does not exceed 25°C. After the addition, a nitrogen stream is passed through the reaction mixture to purge it of any remaining hydrogen chloride. The product is neutralized and worked up as in Preparation 2-3 to give 293 gm (97%) of product.

Influence of Chain Length on the Sphere-to-Rod Transition in Alkyl Sulfate Micelles

Using Quasielastic light scattering spectroscopy (QLS) we have deduced the mean hydrodynamic radius (Rh) of alkyl sulfate micelles as functions of chain length (number of carbons nc = 8-16), temperature (0-85 deg C), detergent concentration (0.01-4g/dL), and NaCl concentration (0.1-2 M).In the region of low chain length (nc h values (extrapolated to the cmc) increase approximately linearly with the chain length.These results combained with Huisman's aggregation numbers (nw(cmc)) are consistent with a micellar shape that is close to spherical (axial ratio less than 2).Under conditions of high NaCl concentrations of high NaCl concentration the micelles exhibit a temperature-dependent growth from small spherical aggregates into long spherocylindrical micelles at concentrations above the cmc.With increasing chain length the temperature dependence of Rh becomes stronger and the NaCl and detergent concentrations needed for micellar growth become smaller.Light scattering intensity measurements confirm a rodlike growth for these micelles at all chain lengths.From these Rh measurements, values of the thermodynamic parameter K governing the sphere-to-rod transition are determined by using an extension of our previous thermodynamic model (Missel et al., J.Phys.Chem., 84, 1044 (1980)).A quantitative analysis of the dependence of K on chain length, temperature, and NaCl concentration provides new insights into energetic factors which govern the structure and growth of micelles.
