The volatile gases, such as CO 2, Cl 2, N 2 or oxides of nitrogen, can be eliminated via washes, using a conventional process.ģ. Chromium(III)-containing waste sulfuric acid remains. NO 2 and SO 3 H groups are converted to oxides of nitrogen and sulfuric acid respectively. In such an oxidation, the organic carbon is oxidized to CO 2, and the chloride to Cl 2. by boiling with chromic acid, the sulfuric acid content of the solution generally being from 45 to 50%. 1-chloro-5-nitrotoluenesulfonic acid or isomers of this, can be completely destroyed in sulfuric acid at elevated temperatures, ie. Examples of compounds which do not readily undergo biodegradation are mononuclear or polynuclear aromatic compounds present in chlorinated, sulfonated and/or nitrated or amidated form. C01P2006/82- Compositional purity water contentįurthermore, waste acids which have a high chromium(III) content and a low sulfuric acid content may be obtained if organic compounds which do not readily undergo biodegradation and are present in waste sulfuric acids are disposed of by oxidation with chromium trioxide.C01P2006/00- Physical properties of inorganic compounds.C01P2002/82- Crystal-structural characteristics defined by measured data other than those specified in group C01P2002/70 by IR- or Raman-data.C01P2002/80- Crystal-structural characteristics defined by measured data other than those specified in group C01P2002/70.C01P2002/00- Crystal-structural characteristics.C01P- INDEXING SCHEME RELATING TO STRUCTURAL AND PHYSICAL ASPECTS OF SOLID INORGANIC COMPOUNDS.C01G37/006- Compounds containing, besides chromium, two or more other elements, with the exception of oxygen or hydrogen.C01G- COMPOUNDS CONTAINING METALS NOT COVERED BY SUBCLASSES C01D OR C01F.C14C3/00- Tanning Compositions for tanning.TANNING, IMPREGNATING, FINISHING APPARATUS THEREFOR COMPOSITIONS FOR TANNING C14C- CHEMICAL TREATMENT OF HIDES, SKINS OR LEATHER, e.g.Assignors: HAHN, ERWIN, LACH, DIETRICH, OSTERTAG, WERNER, WIENAND, HENNING Application granted granted Critical Publication of US4629616A publication Critical patent/US4629616A/en Anticipated expiration legal-status Critical Status Expired - Fee Related legal-status Critical Current Links Google has not performed a legal analysis and makes no representation as to the accuracy of the date listed.)
