General Description

Sodium 1-dodecanesulfonate is an ion-pairing reagent and increases the retention of thiabendazole on the HPLC column during determination of thiabendazole in citrus fruit and banana. It is a surfactant standard.

Synthesis

The general procedure for the synthesis of sodium dodecyl sulfonate from bromododecane was as follows: to a 250 mL round bottom flask was added an ethanol solution (40 mL) of 1-bromododecane (5 g, 20.06 mmol, 1.00 eq.) and an aqueous solution (40 mL) of sodium sulfite (5.2 g, 2.00 eq.). The resulting mixture was heated and reacted at 80 °C overnight. After completion of the reaction, the mixture was cooled to room temperature and extracted with ethyl acetate (100 mL x 2). The organic phases were combined, washed with saturated saline (30 mL x 2), dried over anhydrous sodium sulfate for 15 min, and concentrated under reduced pressure to give the crude product. The crude product was ground with hexane-methanol mixed solvent (20 mL×3) to obtain sodium dodecyl sulfate (5.2 g, 92% yield) as a white solid.

Purification Methods

Recrystallise it twice from EtOH and dry it in an oven at 105o for 2hours. It picks up moisture to form the 3.5H2O. Its hydrate crystallises in several phases. [Tartar & Wright J Am Chem Soc 61 543 1939, Reed & Tartar J Am Chem Soc I 57 571 1935, Beilstein 4 III 27, 4 IV 64.]
