A process of co-feeding gaseous ethylene with liquid allyl alcohol in the presence of a catalyst to produce 1,4-butanediol and n-propanol may include: introducing a gaseous mixture of ethylene, carbon monoxide and hydrogen into a reactor in the presence of a hydroformylation catalyst in a solvent; introducing liquid allyl alcohol (AA) into the reactor; and carrying out hydroformylation reaction at a temperature between 50 and 100&#xb0; C. to obtain hydroformylation products.

Co-feeding ethylene with allyl alcohol in hydroformylation to make 1,4-butanediol and n-propanol

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.
