Method of recovering manganese values from a mixture obtained by catalytically oxidizing a paraffin with gaseous oxygen |
摘要 |
When paraffins having a chain of 10 - 40 carbon atoms are reacted with gaseous oxygen in the presence of a manganese bearing catalyst, manganese is present in the oxidation mixture partly as a solute in the liquid mixture, and partly as a sludge. When the oxidation mixture is extracted with a dilute mineral acid, practically the entire manganese values present in the mixture are found in the aqueous extract which is free of significant amounts of organic matter. When a more concentrated aqueous acid is used in the extraction, practically the entire manganese values present are converted to a precipitate which is readily recovered and may be dissolved in water for further processing.
