Procedure

5-Bromo-1-pentene (199.74 g), sodium sulfite (202.67 g), and water (650 ml) were mixed at room temperature. Under reflux, the solution was stirred for 19 hours. After cooling to room temperature, t-butyl methyl ether was added thereto. The aqueous layer separated was concentrated and dehydrated azeotropically with toluene. Thus, sodium 4-pentene-1-sulfonate (1) containing inorganic substances (387.51 g) was obtained as white solid.
