Bis-(#-hydroxyalkyl)-sulfones are prepared by reacting salts of hydroxy-methanesulphinic acid with 1,2-epoxides having from 2C to 20C in inert solvents at temperatures of 0-100 C., pH of 4 to 10 and with the addition of an acid. Preferably, the sodium, potassium or zinc salts are used, with water as the solvent. The acids include H 2 SO 4 , HC1, H 3 PO 4 , HCO 2 H or CH 3 CO 2 H. Hydroxymethanesulphinic acid salts are made by reacting a bisulphite, e.g. sodium metabisulphite with formaldehyde and reducing for example with sodium amalgam. |
