摘要： An improved process for separation of valuable components of a waste stream resulting from production of an olefin polymerization procatalyst by the addition to the waste stream of a separation solvent of intermediate boiling point, subjecting the resulting mixture to a first distillation zone to separate the desired waste stream components from the upper portion of the zone and passing the bottoms product to a second distillation zone wherein separation solvent is recovered from the upper portion of the zone for recycle and passing the bottoms product to disposal or further processing.
