- a typical synthesis of these compounds is provided in the following Synthesis Example.
- the resulting solid is dissolved in 125 ml hot water, allowed to cool to room temperature and the resulting solution filtered through Whatman No.l paper (a trace of insoluble material is collected on paper). 1000 ml ethanol is added to the solution and immediately a precipitate forms. This is allowed to stand overnight and the solid is filtered off using vacuum filtration and No.54 paper. The collected solid on the pad is then washed with 200 ml of 90:10 ethanol: water and then with 100ml ethanol and then dried to constant weight in vacuum desiccator over sodium hydroxide pellets to provide the desired product.
- the alpha-sulfonated laurate ester of ethoxylated (2 times) isethionate is prepared similar to the synthesis method described in Synthesis Example 1 but using sodium 2-[2-(2-hydroxyethoxy)ethoxy]ethanesulfonate in place of the sodium salt of 2-(2-sulfoethoxy)ethanol.
- This starting material is prepared as follows.
- NMR(DMSO-dg) shows that the reaction is complete by the disappearance of the isethionate peaks at ⁇ 53.5ppm and ⁇ 57.4ppm.
- the solution is cooled to room temperature and neutralized to pH 7 with 57.4g of a 16.4% solution of p- toluenesulfonic acid monohydrate in diethylene glycol. (Alternatively, methanesulfonic acid may be used.)
- the ⁇ C-NMR spectrum of the product shows resonances at ⁇ 51ppm (-CH2SO3Na) , ⁇ 60ppm (-CH2OH), and at ⁇ 69ppm, ⁇ 72ppm, and ⁇ 77ppm for the remaining four methyienes.

- This starting material is prepared as follows.
- Sodium hydroxide pellets (MCB, 5.5g, 0.138 mol) are added, followed by triethylene glycol (Aldrich, 448.7g, 3.0 mol).
- the triethylene glycol can be purified by heating with strong base such as NaOH until color stabilizes and then distilling off the purified glycol for use in the synthesis. The solution is heated at 190C° under argon overnight as water distills from the reaction mixture.
- a ⁇ C-NMR(DMSO-dg) shows that the reaction is complete by the disappearance of the isethionate peaks at ⁇ 53.5ppm and ⁇ 57.4ppm, and the emergence of product peaks at ⁇ 51ppm (-CH2SO3Na) , ⁇ 60ppm (-CH2OH), and at ⁇ 67ppm, ⁇ 69ppnvand ⁇ 72ppm for the remaining methyienes.

- a more soluble buffer can be more effective in controlling pH during the stripping of excess triethylene glycol.
- a more soluble buffer is the salt of N- methylmorpholine with methanesulfonic acid.
- the pH can be controlled by frequent or continuous addition of acid such as methanesulfonic acid to maintain a pH near neutral during the stripping of excess glycol.
- the material is believed to contain a low level of the disulfonate arising from reaction of both ends of the triethylene glycol with isethionate. However, the crude material is used without further purification.
- the sodium salt of allyl alphasulfopalmitate is reacted with 1.0 molar equivalent of sodium metabisulfite at a pH of 3-4 in water using a redox initiator system as in the above example.
