摘要: An exothermic chemical reaction, for example, hydroformylation, is carried out in a series of loop reactors. Fresh reactant feed is supplied not only to the first reactor in the series but also to the second reactor, thereby achieving improved overall throughput while maintaining a stable temperature in at least the first reactor.

摘要: The gas cycle in a high pressure hydroformylation reaction using a series of at least two reactors is controlled to optimise yield, conversion and selectivity and to control reaction temperature. The control is achieved through balancing fresh gases and recycle gases in each of the reactors and as an optional feature the use of hydrogen off gases from the downstream hydrogenation used in the conversion of the hydroformylation reaction product to product alcohols.

摘要: In a hydroformylation reaction, the circulation and recovery of cobalt carbonyl in a cobalt catalyst cycle using carbonylate as an intermediate and acidification thereof, is improved by supplying an aqueous sulfuric acid solution containing less than 16% wt of sulfuric acid to the carbonylate to control sulfuric acid concentration in the carbonylate/acid mixture, before accounting for any acid consuming reaction, to a value of from 2% to 10% by weight. Single step and multistage liquid/liquid extraction techniques as well as vapor/liquid extraction techniques followed by the absorption of cobalt from the vapor in an organic liquid both benefit from this improvement.
