Malodors in raw materials contribute to unacceptable products as well as the need to use higher levels of fragrance. One such example was the synthesis of sodium lauryl ethoxy sulfate (SLES), a major surfactant used in personal care products. This material is produced by ethoxylation of lauryl alcohol followed by sulfonation. Often it is necessary to add a final bleaching step to minimize...

Initial Batch Reactor Studies. An agitated 2000 ml thick-walled glass reactor was blanketed with nitrogen and operated at 50°C. Vinyl acetate containing about 15 ppm hydroquinone was used without purification. The ionic emulsifier was Sipex EST-30, advertised as a sodium tridecyl ether sulfate, and the nonionic surfactant was Siponic L-25, a lauryl alcohol ethoxy-late. Table I shows the recipes and properties of the three seed latexes produced in the batch reactor. Essentially complete conversions were obtained in 30 to 45 minutes, but with a temperature rise of almost 50°C. 

Derivatized polyethers such as polyether sulfate have been investigated for both positive- and negative-ion calibration [11]. Although poly ether sulfates are not commercially available, they are easily synthesized. Lauryl sulfate ethoxy-lates were also used as calibrants for negative-ion ESI. Polyether amines and quaternary ammonium salts were used as positive-ion calibration solutions [11]. These commercially available compounds do not exhibit significant sodium or potassium adducts, and they are more easily flushed out of the mass spectrometer ion source than are nonderivatized polyethers. In addition, doubly charged poly ether diamines can produce reference peaks at low m/z values.
