Process for separating sulfuric acid and carboxylic acids |
abstract |
- i -PATENT APPLICATION OF Phillip D. T. Davies and Lawrence S. Kirch FOR IMPROVED PROCESS FOR SEPARATING SULFURIC ACID AND CARBOXYLIC ACIDS Abstract of the Disclosure The amount of water required to effect efficient separation of a mixture of sulfuric acid and carboxylic acids by distillation, is reduced, by diluting the mixture while in the distillation column with sufficient water to provide a water:sulfuric acid mole ratio of about 1:1. The heat generated by the internal dilution causes separ-ation within the column and permits higher distillation pot tempera-tures, and thereby promotes excellent separation. Feeding the dilu-tion water to the column below the feed mixture further promotes the separation. |
