METHOD OF NEUTRALIZATION AND UTILIZATION OF THE AGGRESSIVE CHEMICAL COMPOUNDS Russian patent published in 2006 - IPC B01D53/60 B01D53/50 B01D53/56 

FIELD: chemical industry; methods of neutralization and a utilization of the aggressive chemical compounds.

SUBSTANCE: the invention is pertaining to the field of neutralization and a utilization of the aggressive chemical compounds, in particular, the saturated with the anhydrides acid-containing compounds and wastes. The neutralization is applied to the smoke mixture containing the sulfuric anhydride and chlorosulfonic acid, or the oxidizing agent of the rocket propellant based on of the nitric acid containing a dimer of the nitrogen dioxide. For neutralization use the hydrolyzed dispersible aluminosilicates based of the natural clays selected from: hydromicaceous Cambrian clay, montmorillonite clay, kaolinite clay or on the basis of their mixtures. At that the hydrolyzed dispersible aluminosilicates, which are taken at least in equal shares with an aggressive chemical compound, are prepared at the following ratio of components (in mass shares): a dry substance - 1.0-2.5, water - 1.0. The invention allows to neutralize the aggressive wastes and to produce the useful product with the sorption activity.

EFFECT: the invention ensures neutralization of the aggressive wastes and production of the useful product with the sorption activity.
