    摘要： Processes for recovering at least one triarylphosphine from a Group VIII metal catalyst triarylphosphine complex mixture are provided. The processes are particularly useful for recovering the triarylphosphine from spent Group VIII metal catalyst complex mixtures. The processes include the steps of (i) forming a distillate from a Group VIII catalyst complex mixture containing a Group VIII metal catalyst complex, a triarylphosphine, and a light ends component wherein the distillate contains at least a portion of the triarylphosphine as a vapor and at least a portion of the light ends component as a vapor; (ii) cooling the distillate to a temperature below the boiling point of the light ends component to form a condensate; (iii) crystallizing at least a portion of the triarylphosphine using the light ends component as a crystallizing liquid; and (v) recovering the crystallized triarylphosphine from the condensate. ® KIPO & WIPO 2008
