Abstract
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° C. to obtain hydroformylation products.
