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