| abstract |
A hydrof ormylation process for the production of alcohols comprising reacting, in a reactor system comprising one or more feed streams, a reaction environment and an output stream, a feedstock composition comprising a compound having at least one olefinic carbon-to-carbon bond with hydrogen and carbon monoxide in the presence of an organophosphine modified cobalt hydrof ormylation catalyst, wherein the hydrof ormylation process is carried out in the reaction environment which comprises at least two reaction zones, comprising a first reaction zone, a second reaction zone and, optionally, one or more later reaction zones, wherein the molar ratio of hydrogen to carbon monoxide entering the first reaction zone is in the range of from 0.5 to 1.65, and wherein water is added into the reactor system. |
