Palladium palladium is one of the platinum group elements (ruthenium, rhodium, palladium, osmium, iridium, platinum), the periodic system is a group VIII element, the element symbol Pd, the atomic number 46, and the atomic weight 106.42. Palladium was isolated from crude platinum in Wollaston, England, in 1803. The content of the crust is 1 × 10-6%, which is the most abundant platinum group element. In nature, it exists as a simple substance or alloy, and it is symbiotic with other platinum elements, especially with platinum, such as the original platinum ore, nickel copper sulfide, nickel pyrite, Palladium containing chalcopyrite and so on. Palladium is produced industrially from platinum ores or as a by-product of refining copper and nickel ores. Palladium is a silver-white metal. Melting point 1554 ° C, boiling point 2970 ° C, density 12.02g/cm 3. Soft texture, good ductility and plasticity. Bulk palladium can absorb large amounts of hydrogen. The hydrogen absorption capacity of sponge-like or colloidal palladium is stronger. At room temperature, 1 volume of sponge Palladium absorbs 900 volume of hydrogen. When heated to 40~50 °c, most of the hydrogen is released, and all of the hydrogen is released at high temperature.
Palladium is a kind of catalyst with excellent catalytic performance. The applicable reaction types include hydrogenation, isomerization, disproportionation, dehydrogenation and oxidation, in petrochemical applications even more than platinum catalyst. Palladium Catalysts are also used for the treatment of toxic waste gases emitted from nitric acid plants. Palladium and its alloys can be used instead of platinum for jewelry, for example, alloys made with smaller amounts of palladium and gold are the best "Platinum". Palladium dichloride can be obtained by reacting Palladium with chlorine or aqua regia. Palladium dichloride can be used as a catalyst for Olefin oxidation, and also used in medicine, electroplating, photography, detection of trace carbon monoxide and preparation of other catalysts.

Noble metal catalyst Noble metal catalyst refers to a noble metal material that can change the rate of a chemical reaction without itself participating in the final product of the reaction. In 1831, the British Phillips (philips) proposed to produce sulfuric acid by the contact method of platinum as catalyst, and the method was industrialized in 1875, which is the earliest industrial application of noble metal catalysts. Almost all noble metals can be used as catalysts, but platinum, palladium, rhodium, silver, ruthenium and the like are commonly used, among which platinum and rhodium are the most widely used. According to the category of catalytic reaction, noble metal catalysts can be divided into two categories: homogeneous catalysis and heterogeneous catalysis. Catalysts for homogeneous catalysis are generally soluble compounds (salts or complexes), such as palladium chloride, Rhodium chloride, Palladium acetate, rhodium carbonyl, Rhodium triphenylphosphine carbonyl, and the like. The catalyst for heterogeneous catalysis is an insoluble solid, and its main morphology is a metal wire mesh state and a porous inorganic support supported metal state. Metal wire mesh catalyst (such as platinum mesh, silver mesh) the scope of application and the amount of limited. The vast majority of heterogeneous catalysts are supported on noble metals, such as Pt/Al2O3, Pd/C, Ag/Al2O3, Rh/process, and the heterogeneous catalytic reaction accounts for 80% ~ 90%.
1. Diphenyl carbonate can be prepared by reacting phenol with carbon monoxide in the presence of triethylamine in the presence of palladium chloride as catalyst.
2, using isobutylene as raw material, copper chloride-palladium chloride as catalyst, potassium chloride as co-catalyst, decane and water two-phase diluent for oxidation and molecular rearrangement, Can be prepared from methyl ethyl ketone products. The by-product, tert-butyl alcohol, is converted to isobutylene by catalytic dehydration.
3, with the development of petrochemical industry, using ethylene as raw material, oxygen is directly oxidized to synthesize acetaldehyde in one step through hydrochloric acid aqueous solution catalyst containing palladium chloride and copper chloride.
4, 2-methylfuran as raw material, in aqueous solution, palladium chloride as catalyst, at a pressure of 0.25MPa heated to 30 ℃, hydrogenation, ring opening, can produce 3-acetyl N-propanol crude. Then vacuum distillation refining, can be prepared fine.
Application for the preparation of special catalysts, molecular sieves; Preparation of non-conductor material coating; Production of gas sensors.
used as analytical reagent
It is mainly used in the manufacture of special product catalysts, molecular sieves, and the preparation of surfactants for the coating of non-conductor materials, production of gas sensitive element, etc.
It is mainly used as a catalyst for the production of acetaldehyde from ethylene and other palladium-based catalysts. Preparation of molecular sieve, preparation of non-conductor material plating surface activator. For the manufacture of gas-sensitive components.
determination of palladium, Mercury, thallium and iodine, purification of rare gases, palladium chloride test paper to test carbon monoxide, Cobalt; Catalyst, terminal olefin (α-olefin) to form methyl ketone oxidation catalysis; the oxidation of alkenes to aldehydes in aqueous solution using air as an oxidant by The Waker reaction is used to synthesize semiconducting metal-containing polymers with a polypyrrole skeleton that is minimal in energy and close to planar.
for ICP-AES, AAS, AFS, ICP-MS, ion chromatography, etc. Standard solutions were used for titration analysis.
production method Palladium powder is added to a reactor containing hydrochloric acid, and air is introduced for oxidation reaction under stirring, the palladium chloride solution is generated, and the solution is purified, filtered, evaporated and concentrated, cooled and crystallized, centrifuged and dried to obtain a finished palladium chloride product.
