Process for removing a cobalt or rhodium carbonyl compound from an aqueous 3-hydroxypropanal solution |
| abstract |
The cobalt or rhodium carbonyl compound is (a) an aqueous solution of 3-hydroxypropanal, at least one water soluble cobalt or rhodium, by contacting oxygen with a 3-hydroxypropanal solution at temperatures ranging from about 5 to about 45 ° C. under acidic conditions. To produce an oxidative product mixture comprising species and byproduct carbon monoxide; (b) removing byproduct carbon monoxide immediately from the oxidation product mixture; (c) removing the at least some soluble metal compound from the oxidation product mixture by contacting the oxidation product mixture with an acidic ion exchange resin maintained at a temperature of about 45 ° C. or less. Is removed from the aqueous solution. This method is useful for the preparation of 1,3-propanediol, for example, via intermediate 3-hydroxypropanal solution containing residual carbon dioxide and insoluble cobalt or rhodium catalyst compounds from ethylene oxide. |
