Production of a concentrated aqueous cobalt salt solution
Abstract
Abstract A process for the production of an aqueous solution of cobalt salts of aliphatic carboxylic acids having from two to eight carbon atoms which contains from 3 to 8 percent by weight of cobalt and is suitable as a catalyst solution for the oxo synthesis, in which process an aqueous solution of cobalt salts obtained by treating an oxo reaction mixture with oxidants in an aqueous acid medium at elevated temperature and separation of the aqueous solution and containing from 0.5 to 1.5 percent by weight of cobalt is treated with from 0.01 to 3 percent by weight, with reference to the aqueous cobalt salt solution to be treated, of a noble metal from group VIII of the Periodic System in the presence of an amount equivalent to the amount of cobalt contained in the aqueous solution of an aliphatic carboxylic acid having from two to eight carbon atoms, and subsequent concentration by distillation.
