Abstract
Butanediol production processes are described herein. In some embodiments, the processes include contacting an allyl alcohol stream with a hydroformylation catalyst in the presence of a gas stream including carbon monoxide and hydrogen under hydroformylation conditions sufficient to form a hydroformylation product stream including a butanediol intermediate, wherein the allyl alcohol stream includes less than 98 wt. % allyl alcohol.
Claims11
A process comprising:
- contacting an allyl alcohol stream with a hydroformylation catalyst comprising rhodium phosphate at a feed concentration of 0.3-3.3 wt. % in the presence of a gas stream comprising carbon monoxide and hydrogen under hydroformylation conditions sufficient to form a hydroformylation product stream comprising a butanediol intermediate, wherein the allyl alcohol stream comprises less than 98 wt. % allyl alcohol.
