Abstract: Systems and methods of recovering 2-ethyl hexanol from crude alcohol are disclosed. The crude alcohol originates from a reactor that produces 2-ethyl hexanol and is first distilled in a first distillation column The distillate from the first distillation column is then further distilled in a second distillation column. A side stream is drawn from the second distillation column and recycled to the reactor that produces 2-ethyl hexanol. The bottom stream from the second distillation column is mixed with the bottom stream from the first distillation column. The combined stream is further distilled in a third distillation column to produce a 2-ethyl hexanol product stream.

Abstract: A method of storing and/or transporting oxo alcohol, comprises: combining an oxo alcohol having an initial aldehyde content X and an initial peroxide content Y with 5 ppm to 100 ppm of a phenolic antioxidant, preferably a phenolic antioxidant without ester linkage groups; and storing and/or transporting the oxo alcohol. The oxo alcohol can be used to produce a plasticizer, e.g., without adversely affecting color.

Abstract: A method of recovering 2-ethyl hexanol (2-EH) from crude alcohol that includes the 2-ethyl hexanol, 2-ethyl, 3-propyl acrolein (EPA), and 2-ethylhexanal (EHA) is disclosed. The crude alcohol stream is first separated into a first stream of primarily 2-EH, a second stream of primarily EPA and 2-EH collectively, and a third stream of primarily 2-EH and EHA collectively. The second stream and the third stream are combined to form a combined stream. The combined stream is processed further to form a first product stream comprising primarily 2-EH and a second product stream comprising primarily, 2-EH, EHA, and EPA collectively.
