Analyzing the synthesis route of Sodium isethionate

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,1562-00-1, its application will become more common.

Reference of 1562-00-1, In the chemical reaction process,reaction time,type of solvent,can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product.An updated downstream synthesis route of 1562-00-1 as follows.

Example A; 31 g of (E)-10-pentafluorosulfanyldec-9-enecarbonyl chloride, prepared as in Example 1, are dissolved in 100 g of THF, 2-hydroxyethanesulfonic acid Na salt (15 g) and triethylamine (10 g) are added, and the mixture is stirred at 30 C. for 6 hrs.In order to isolate the product, the mixture is added to ice/methyl tert-butyl ether, the water phase is extracted with this solvent, and all org. phases are evaporated. Ethanol and then 1.2 equivalents of sodium hydroxide are added. The mixture is warmed briefly, and, after cooling, the crystals formed are isolated and dried.

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,1562-00-1, its application will become more common.
