Abstract
A method of treating the residue generated in the production of diphenylphosphinous chloride is presented. The method comprises extracting the aluminum content of the residue by contacting the residue with an organic solvent to produce a mixture which when hydrolyzed results in a two-phase solution, the organic phase of which can be incinerated.
