- 2.4 Chemical Properties
- Palladium chloride is a dark brown powder, hygroscopic (absorbs moisture from the air). It is incompatible with acids, aluminium, ammonia, magnesium, nitrates, zinc, heat, thiocyanates, and organic solvents. Thermal decomposition of palladium chloride may release chlorine, hydrogen chloride, and oxides of palladium. It is used as a catalyst, photographic, and electroplating reagent. Palladium and its alloys are used as catalysts in the (petro)chemical and, above all, in the automotive industries. Applications of palladium compounds for electronics and electrical technology include use in metallisation processes (thick film paste), electrical contacts and switching systems, in the synthesis of semiconducting metal-containing polymers in which the polypyrrole backbone has a conformational energy minimum and is nearly planar. Palladium chloride is a stable chemical substance and is incompatible with strong oxidising agents.

3. Use and Manufacturing
- 3.1 General Description
- Dark brown crystals.
- 3.2 Produe Method
- The palladium powder is added to the reactor containing hydrochloric acid, with stirring, passing the air, an oxidation reaction is performed, generating palladium chloride solution, the solution is purified, filtered, concentrated by evaporation, cooling and crystallization, centrifugal separation, and dried to obtain a palladium chloride finished products.Pd+2HCl+0.5O2→PdCl2+H2O
- 3.3 Purification Methods
- The anhydrous salt is insoluble in H2O and dissolves in HCl with difficulty. The dihydrate forms red hygroscopic crystals that are readily reduced to Pd. Dissolve it in conc HCl through which dry Cl2 is bubbled. Filter this solution which contains H2PdCl4 and H2PdCl6 and on evaporation it yields a residue of pure PdCl2.

- SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.

6. Other Information
- 6.0 Usage
- Catalyst precursor. Palladium(II) chloride is used to remove the stain present in stainless steel . Its solutions are used to test the corrosion-resistance of stainless steel. It is used in carbon monoxide detectors. It is also used for cosmetic tattooing of leukomas in the cornea and in the preparation of palladium(II) iodide by reacting with potassium iodide. It is involved in the synthesis of semiconducting metal-containing polymers. It is used as a catalyst for carbonylation of organic tellurides and deamination of phenethylamines to phenyl substituted pyrroles with copper(I) as co catalyst.
