Sodium dodecylsulfonate Use and Manufacturing
To a 250 mL row1d bottom f1ask vas added a solution of 1-bromododecane 222a (5 g, 20 06 mmol, 1.00 equiv.) in ethanol (40 mL) and a solution ofNa2S03 (5.2 g, 2.00 equiv.) inwater (40 mL) The resulting mixture was heated at 80°C overnight. After cooling to roomtemperature, the mixture was extracted with ethyl acetate (100 mL x 2). The combinedorganic extracts were washed with brine (30 mL x 2), dried over anhydrous sodium sulfate15 and concentrated to a residue which was triturated ·with hex:mes (20 mL x 3) to give sodiumdodecane-1-sulfonate 222b (5 2 g, 92percent) as a white solid.
Used in industrial detergents, textile industry cleaning agents; dyeing auxiliaries, flotation agents for mineral processing. It is the main ingredient of detergent. It is often used in the DNA extraction process to denature the protein and separate it from the DNA. This product is an anionic surfactant, widely used in pesticides, fertilizers, metals, building materials, rubber, textiles, emulsifiers, floating agents, foaming agents, penetrants in the printing and dyeing industry, etc.
