Title: Improvements in or relating to the process for the production of aldehydes
IPC: C07C27/22
Filed: 1951-11-22
Abstract: In an Oxo process at 1500-4500, preferably 2500-3500 p.s.i.g and from 275-450, preferably 300-375 DEG  F., in the presence of a non-stationary cobalt catalyst the aldehyde product containing solid oil-insoluble forms of cobalt in suspension is withdrawn from the reaction zone and passed to a soaking zone together with unreacted CO and H2 where it is maintained for 1-60, preferably 5-30 mins., at substantially the pressure of reaction and at 150-300 DEG  F., preferably 200-250 DEG  F., for conversion of solid cobalt to cobalt carbonyl the aldehyde product cooled to 60-120 DEG  F. then being sent to a gas-liquid separation-zone and at least a portion of the cooled liquid product recycled to the reaction zone, e.g. at about 60-120 DEG  F.  Unreacted gases are preferably recycled to the reactor.  Solid olefine-insoluble catalysts are preferred, e.g. suspensions of cobalt metal, cobalt oxide, carbonate, formate or basic carbonate may be used, and paste, e.g. finely ground cobalt with about 50 per cent. petrolatum, and colloid catalysts.  Aqueous solutions of catalyst may be injected.  The reaction may be started with catalysts such as cobalt oleate or naphthenate and the solid catalysts added subsequently.  Solvents may be present.  Recycled liquid product is preferably added to the upper and intermediate portions of the reactor as well as at the bottom.  Liquid for product recovery is treated in a catalyst removal zone in convention fashion and may be subsequently hydrogenated to alcohols.  Additional solid cobalt catalyst may be added to the soaker.  In illustrative experiments it is shown (1) that solid cobalt catalysts are incompletely converted to the carbonyl under conditions when oil-soluble catalysts are substantially completely converted, (2) that as the temperature of reaction increases the amount of soluble cobalt in the aldehyde effluent decreases, (3) that a soaking temperature of 200-300 DEG  F., especially around 225 DEG  F., is to be preferred and (4) that a relatively short contact time in the soaker is sufficient to dissolve a high degree of cobalt from the relatively coarse slow-reacting oxide.  Specifications 629,915, 647,363 and 660,737 are referred to.
