Abstract
Oil-in-water type emulsions of bis trichloromethyl sulfone which can be made from dimethyl sulfide and sodium hypochlorite. Emulsification is achieved by using the by-product aqueous brine solution from the formation reaction thereby avoiding the ecological problem of brine waste disposal and resulting in a simple one-pot type emulsion preparation procedure. The technique is also particularly well adapted to making mixed biocide concentrate formulations containing emulsified bis trichloromethyl sulfone.
