摘要
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.
