Abstract

The invention is a method of treating the distillation residue from the production of phosphorochloridothionates which comprises draining the residue into agitated cold water to form a slurry and contacting the slurry with chlorine gas in a hydrolyzing zone to decompose the residue and produce decomposition gases in controllable amounts having a decreased sulfur content. The novel method would reduce the amount of sulfur in the decomposition gas and make possible the use of less costly abatement facilities.
