    The present invention relates to an apparatus for producing alcohols from olefins, comprising: a hydroformylation reactor wherein aldehydes are produced from olefins; a catalyst/aldehydes separator; a hydrogenation reactor wherein the aldehydes are hydrogenated to produce alcohols; and a distillation column. The hydroformylation reactor is equipped with a distributor plate, which has a broad contact surface for providing sufficient reaction area for reactants such as olefins and synthesis gas, and allows the reaction mixture to circulate and mix sufficiently, which contribute to excellent efficiency in terms of production of aldehydes. In addition, the hydrogenation reactor suppresses sub-reactions to improve the production yield of alcohols.

    A process for the production of 2-alkylalkanol from an aldehyde is disclosed. The process comprises the steps of: feeding aldehyde to a reactor (42) operated under condensation and dehydration conditions such that reaction occurs and an unsaturated aldehyde is produced; recovering a stream from the reactor (42) comprising the unsaturated aldehyde and feeding said stream to a first hydrogenation reactor (45) operated under conditions such that at least some of the unsaturated aldehyde is converted to 2-alkylalkanol; recovering the stream from the first hydrogenation reactor (45) comprising the 2-alkylalkanol, one or more of unreacted acrolein, alkylalkenol and alkylalkanal and heavies; passing the stream recovered from the first hydrogenation reactor (45) to a first distillation zone (48) where at least some of the heavies are separated from the stream; recovering a stream from the first distillation zone (48) comprising the 2-alkylalkanol, one or more of unreacted acrolein, alkylalkenol and alkylalkanal, said stream having a reduced heavies content when compared to the stream fed to the first distillation zone (48), and feeding said stream to a second hydrogenation reactor (51) operated under conditions such that at least one of the unreacted acrolein, alkylalkenol and alkylalkanal are converted to 2-alkylalkanol; and recovering a stream from the second hydrogenation reactor (51) comprising an increased 2-alkylalkanol content compared to the stream fed to the second hydrogenation reactor (51).
