Abstract
Aluminium oxalate or basic oxalate is obtained in the solid water-soluble state by dehydration of solutions thereof at temperatures which exceed the boiling point of water at the prevailing pressure, or at lower temperatures by using a fine dispersion of the solution with or without a heated current of gas or reduced pressure. In examples, a solution is concentrated until its boiling point reaches 110 DEG C. and is then evaporated to dryness at 120 DEG C.; a solution of basic oxalate is concentrated at 95 DEG C. and then further dehydrated at 90 DEG C. under reduced pressure; and a solution previously concentrated to a syrupy consistency is either spread in thin layers on glass plates and dried at 30-100 DEG C. or sprayed into a closed vessel in countercurrent to a heated current of gas.
