Cl: Encyclopedia II - Oxide - Types of oxides

Oxides of more electropositive elements tend to be basic. They are called basic anhydrides; adding water, they may form basic hydroxides. For example, sodium oxide is basic; when hydrated, it forms sodium hydroxide. Oxides of more electronegative elements tend to be acids. They are called acid anhydrides; adding water, they may form oxygen acids. For example, dichlorine heptoxide is acid; perchloric acid is a more hydrated form. Some oxides can act as both acid and base, at different times. They are amphoteric. An example is aluminium oxide. Some oxides do ...

Cl: Encyclopedia II - Palladium - Applications

When it is finely divided, palladium forms a good catalyst and is used to speed up hydrogenation and dehydrogenation reactions, as well as in petroleum cracking. A large number of reactions in organic chemistry are facilitated by palladium catalysis, many of which involve carbon-carbon bond formation. It is also alloyed and used in jewelry. Other uses; The largest use of palladium today is in catalytic converters. Much research is in progress to discover ways to replace the much more expensive platinum with palladium in this app ...

Cl: Encyclopedia II - Phosphorus trichloride - Uses

World production exceeds one-third of a million tonnes[1]. Phosphorus trichloride is an important starting point for the manufacture of many industrial products containing phosphorus. It is the starting material for organophosphorus compounds which contain one or more (P3+) atoms, most notably phosphites and phosphonates. These compounds do not usually contain the chlorine atoms found in (PCl3). These are lost as hydrogen chloride (HCl) during their synthesis. (PCl3) is however the usual starting compound for their synthesis, since it is the most v ...

Cl: Encyclopedia II - Phosphorus trichloride - Precautions

PCl3 is highly toxic, with a concentration of 600 ppm being lethal in just a few minutes[7]. It reacts violently with water and is highly corrosive. Wear gloves and goggles and work in a fume cupboard (hood), and use an apron and face shield with larger amounts. It is a reducing agent and should be kept away from strong oxidising agents. PCl3 is classified as very toxic and corrosive under EU Directive 67/548/EEC, and the ri ...

Cl: Encyclopedia II - Phosphorus trichloride - Preparation

Phosphorus trichloride is prepared industrially by the reaction of chlorine with a refluxing solution of white phosphorus in phosphorus trichloride, with continuous removal of PCl3 as it is formed. In the laboratory it may be more convenient to use the less toxic red phosphorus[6]. P4 + 6 Cl2 → 4 PCl3 Industrial production of phosphorus trichloride is controlled under the Chemica ...

Cl: Encyclopedia II - Palladium - History

Palladium was discovered by William Hyde Wollaston in 1803. This element was named by Wollaston in 1804 after the asteroid Pallas, which was discovered two years earlier. Wollaston found element 46 in crude platinum ore from South America. He did this by dissolving the ore in aqua regia, neutralizing the solution with sodium hydroxide, NaOH, precipitating platinum as ammonium chloroplatinate through treatment with ammonium chloride, NH4Cl, and then adding mercuric cyanide to form the compound palladium cyanide. Finally, he heated the resulting compound ...

Cl: Encyclopedia II - Palladium - Occurrence

Palladium is found as a free metal and alloyed with platinum and gold with platinum group metals in placer deposits of the Ural Mountains, Australia, Ethiopia, South and North America. However it is commercially produced from nickel-copper deposits found in South Africa and Ontario (the huge volume of ore processed makes this extraction profitable in spite of its low concentration in these ores). About the possibility of producing palladium in reactors or extracting it from spent nucl ...

Cl: Encyclopedia II - Titanium - Applications

Approximately 95% of titanium production is consumed in the form of titanium dioxide (TiO2), an intensely white permanent pigment with good covering power in paints, paper, toothpaste, and plastics. Paints made with titanium dioxide are excellent reflectors of infrared radiation and are therefore used extensively by astronomers and in exterior paints. It is also used in cement, in gemstones, and as a strengthening filler in paper. Recently, it has been put to use in air purifiers (as a filter coating) or in window film on building ...
