A high degree of selectivity towards the formation of butanol and butanal is provided by using the cobalt entity and the biphosphine disulfide in a molar ratio in the range of about 2:1 to about 10:1, based on elemental cobalt and phosphorus. The reaction is conducted at elevated temperature and pressure conditions for a time sufficient to convert methanol to n-butanol and n-butanal.
