Mild sulfonation of detergent‐range internal olefins in a falling‐film reactor results in quantitative conversion to a mixture of β‐sultones, alkenesulfonic acids, and larger‐ring sultones in a molar ratio of ca. 85:10:5. By direct neutralization and hydrolysis under well‐controlled conditions such mixtures can be converted into products that are rich in β‐hydroxysulfonates and have low levels of residual sultones, inorganic sulfate, and free oil.
