ABSTRACT:
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 in a prescribed manner with sufficient water to provide a water:sulfuric acid mole ratio of about 1:1. The heat generated by the internal dilution reduces the energy requirement of the column. Feeding the dilution water to the column below the feed mixture is a key element of the process.
