| titleOfInvention | Processes for producing organophosphorous compounds |
| abstract | The present invention relates to processes for producing organophosporous compositions having low acid content as well as processes for reprocessing partially degraded organophosporous compositions that contain high levels of phosphorous acid. In one embodiment, a process comprises: (a) receiving a solid organophosphite compound that has been recrystallized or triturated, wherein the solid organophosphite compound comprises phosphorous acid; (b) dissolving the solid organophosphite compound in a an aromatic hydrocarbon solvent in the absence of water and free amine, wherein the hydrocarbon solvent comprises an aromatic hydrocarbon, a saturated aliphatic hydrocarbon, or a mixture thereof; and (c) removing undissolved phosphorous acid from the solution, wherein the acid content of the organophosphite following step (c) is 30 ppm or less. |
