Soda soaps produced by aldehyde oxidation can be separated from reactor mixtures of hydrocarbons produced in the catalytic hydrogenation of CO by H₂O or aqueous alcohol solutions when the reaction mixture does not contain free alkali hydroxide. The amount of H₂O or aqueous alcohol solution should be 10-15 times the weight of the soap. To prevent foaming the H₂O or solvent mixture used in extracting the soap contains an anti foam agent such as 10-15% of ethyl alcohol.
