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.
Claims7
A method of treating the residue from the production of phosphorochloridothionates comprising the steps of:
- (a) contacting the residue with water and a chlorinating agent in an amount sufficient to form a chlorinated slurry wherein the amount of sulfur precipitated in the liquid phase is increased;
- (b) hydrolyzing the chlorinated slurry in controllable amounts to produce decomposition gases having a decreased sulfur content, and other by-products comprising sulfur and phosphoric acid.
