Abstract

A method including hydroformylating, with syngas, allyl alcohol in an allyl alcohol feed, to produce a hydroformylation product comprising 4-hydroxybutyraldehyde and 3-hydroxy-2-methylpropionaldehyde; and producing a 1,4-butanediol (BDO) product comprising BDO and 1,3-methylpropanediol via hydrogenation of at least a portion of the hydroformylation product. A method including hydroformylating, with syngas, allyl alcohol in a feed comprising bio-allyl alcohol, to produce a hydroformylation product comprising 4-hydroxybutyraldehyde and 3-hydroxy-2-methylpropionaldehyde; and producing a BDO product comprising BDO and 1,3-methylpropanediol via hydrogenation of at least a portion of the hydroformylation product. A method including hydroformylating, with syngas, bio-allyl alcohol in a feed comprising bio-allyl alcohol, to produce a hydroformylation product comprising 4-hydroxybutyraldehyde and 3-hydroxy-2-methylpropionaldehyde; producing a BDO product comprising BDO and 1,3-methylpropanediol via hydrogenation of at least a portion of the hydroformylation product; and removing a byproduct of the production of the bio-allyl alcohol prior to hydroformylating the bio-allyl alcohol and/or from the BDO-product.
