Example text

The head space is purged with nitrogen, then the tube is stoppered and placed within a pressure tube in a heating block. After heating at 185eC for 10 min, the tube is cooled and 3 mL water is added. The resulting alkyl iodides are extracted with three 1 -mL portions of petroleum ether. The combined extracts are washed free of iodine with two 1-mL portions of 20% aqueous sodium thiosulfate solution, then evaporated to dryness on a water bath. Analysis is by gas chromatography on a 5-ft column of 10% polyethylene glycol diadipate on Celite.

The test tube is shaken, and the petroleum ether layer is pipetted into a second test tube. The contents of the first test tube are extracted with another 2-mL aliquot of petroleum Characterization of Anionic Surfactants 23 ether, and this extract is added to the first. The combined extracts are washed four times with 1-mL portions of 4 M NaOH solution, transferring the petroleum ether layer to a clean test tube after each wash. The petroleum ether phase is dried by addition of 1 g sodium sulfate, transferred to yet another test tube, and evaporated to a small volume in a water bath at 60-70°C.

The methanol solution is evaporated to dryness to expel CHC13, and the residue is redissolved in water or methanol. The HPLC system should be capable of ternary gradient operation and have a column compartment thermostatted at 35°C. Detection is by UV absorbance at 225 nm. 6 x 250 mm. 0 with NaOH. 0 mL/min. A linear gradient is used, beginning with 10:50:40 TBAHSO4/water/acetonitrile. During the first 30 min, ^O is lowered to 10%, increasing CH3CN to 80%. During the following 10 min, TBAHSO4 is dropped to 0%, resulting in a H2O/CH3CN isocratic system, 20:80, which is held for 15 min.
