ドデシル硫酸ナトリウム (JIS K 3363-1990) [合成洗剤の生分解度試験用] 用途と合成の方法
  • 化学的特性White crystalline flakes
  • 使用Anionic detergent
  • 使用hydrophilic tablet lubricant
  • 使用Wetting agent, detergent, especially in the textile industry. Electrophoretic separation of proteins and lipids. Ingredient of toothpastes.
  • 一般的な説明White to pale yellow paste or liquid with a mild odor. Sinks and mixes with water.
  • 空気と水の反応Insoluble in water.
  • 反応プロフィールDODECYL SULFATE is incompatible with strong oxidizers. Sodium dodecyl sulfate is also incompatible with cationic materials and with acids with pH below 2.5. Salts, basic, such as DODECYL SULFATE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydroxide ions and have pH's greater than 7.0. They react as bases to neutralize acids. These neutralizations generate heat, but less or far less than is generated by neutralization of the bases in reactivity group 10 (Bases) and the neutralization of amines. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible.
  • 健康ハザードInhalation of dust causes sneezing and coughing. Ingestion of large amounts causes irritation of stomach. Dust irritates eyes and may cause burns on prolonged contact. Contact with skin causes some irritation; continued exposure to water solution causes drying out and cracking.
  • 火災危険Flash point data for Sodium dodecyl sulfate are not available; however, Sodium dodecyl sulfate is probably combustible.
  • 純化方法Purify this detergent by Soxhlet extraction with pet ether for 24hours, followed by dissolution in acetone/MeOH/H2O 90:5:5(v/v) and recrystallisation [Politi et al. J Phys Chem 89 2345 1985]. It has been purified by two recrystallisations from absolute EtOH, aqueous 95% EtOH, MeOH, isopropanol or a 1:1 mixture of EtOH/isopropanol to remove dodecanol, and dried under vacuum [Ramesh & Labes J Am Chem Soc 109 3228 1987]. SDS has also been purified by repeatedly foaming whereby a 0.15% aqueous solution is made to foam and the foam is discarded, then the H2O is removed in vacuo and the residue is diluted to the required concentrations [see Cockbain & McMullen Trans Faraday Soc 47 322 1951] or by liquid-liquid extraction [see Harrold J Colloid Sci 15 280 1960]. Dry it over silica gel. For DNA work it should be dissolved in excess MeOH passed through an activated charcoal column and evaporated until it crystallises out. It has also been purified by dissolving in hot 95% EtOH (14mL/g), filtering and cooling, then drying in a vacuum desiccator. Alternatively, it is crystallised from H2O, vacuum dried, washed with anhydrous Et2O and dried in vacuum again. These operations are repeated five times [Maritato J Phys Chem 89 1341 1985, Lennox and McClelland J Am Chem Soc 108 3771 1986, Dressik J Am Chem Soc 108 7567 1986]. [Beilstein 1 IV 1847.]
