1. , for producing the method containing oxygen alcohol simultaneously, comprising:

  • A () provides flow of propylene and synthesis air-flow;

    B flow of propylene described in () hydroformylation and described synthesis air-flow are to produce the first aldehyde stream comprising butyraldehyde-n (NBAL) and isobutyric aldehyde (IBAL);

    C () aldol condensation at least partially described NBAL comprises the second aldehyde stream of 2-ethyl hexanal (EPA) with production;

    And(d) simultaneously hydrogenation at least partially described first aldehyde stream and at least partially described second aldehyde stream comprise the alcohol stream of propyl carbinol, isopropylcarbinol and 2-Ethylhexyl Alcohol with production;

    Wherein, step (d) is carried out in single hydrogenation reactor.
