Low pressure process for the preparation of methanedisulfonic acid alkali metal salts |
| abstract |
The invention provides a process for producing alkylpolysulfonic acid alkali metal salts such as methanedisulfonic acid alkali metal salts. The process involves heating an aqueous solution of about two molar equivalents of an alkali metal sulfite to a temperature of from about 70° C. to about 90° C.; adding about one molar equivalent of a dihaloalkane to the aqueous alkali metal sulfite solution at a temperature of about 70-90° C.; and then separating the resulting alkyldisulfonic acid alkali metal salt from the reaction solution. The dihaloalkane is added at a pressure of about 1.1 atmospheres or less. |
