Ludwig Mond
Ludwig Mond FRS (7 March 1839 – 11 December 1909) was a German-born, British chemist and industrialist. He discovered an important, previously unknown, class of compounds called metal carbonyls. Education and career Ludwig Mond was born into a Jewish family in Kassel, Germany. His parents were Meyer Bär (Moritz) Mond and Henrietta Levinsohn. After attending schools in his home town, he studied chemistry at the University of Marburg under Hermann Kolbe and at the University of Heidelberg under Robert Bunsen but he never gained a degree. He then worked in factories in Germany and the Netherlands before coming to England to work at the factory of John Hutchinson & Co in Widnes in 1862. He worked in Utrecht for the firm of P. Smits & de Wolf from 1864 to 1867 and then returned to Widnes. Here he formed a partnership with John Hutchinson and developed a method to recover sulphur from the by-products of the Leblanc process, which was used to manufacture soda ash. In 1872 Mo ...

Leblanc Process
The Leblanc process (pronounced leh-blaank) was an early industrial process for making ''soda ash'' (sodium carbonate) used throughout the 19th century, named after its inventor, Nicolas Leblanc. It involved two stages: making sodium sulfate from sodium chloride, followed by reacting the sodium sulfate with coal and calcium carbonate to make sodium carbonate. The process gradually became obsolete after the development of the Solvay process. Background Soda ash (sodium carbonate) and potash (potassium carbonate), collectively termed ''alkali'', are vital chemicals in the glass, textile, soap, and paper industries. The traditional source of alkali in western Europe had been potash obtained from wood ashes. However, by the 13th century, deforestation had rendered this means of production uneconomical, and alkali had to be imported. Potash was imported from North America, Scandinavia, and Russia, where large forests still stood. Soda ash was imported from Spain and the Canary I ...

Sulfur
Sulfur (or sulphur in British English) is a chemical element with the symbol S and atomic number 16. It is abundant, multivalent and nonmetallic. Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S8. Elemental sulfur is a bright yellow, crystalline solid at room temperature. Sulfur is the tenth most abundant element by mass in the universe and the fifth most on Earth. Though sometimes found in pure, native form, sulfur on Earth usually occurs as sulfide and sulfate minerals. Being abundant in native form, sulfur was known in ancient times, being mentioned for its uses in ancient India, ancient Greece, China, and ancient Egypt. Historically and in literature sulfur is also called brimstone, which means "burning stone". Today, almost all elemental sulfur is produced as a byproduct of removing sulfur-containing contaminants from natural gas and petroleum.. Downloahere The greatest commercial use of the element is the production o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Utrecht (agglomeration)
The city of Utrecht and the surrounding cities, villages, and townships form an agglomeration in the middle of The Netherlands. It is located entirely in the province of Utrecht, and is the eastern part of so-called North Wing the larger Randstad urban area. The agglomeration has a population of about 690.000 people (a rough estimate based on data collected in 2001-2012). The following towns are commonly recognized as part of the agglomeration: This interpretation of what is to be acknowledged the greater Utrecht area, is the most common one. The physically joint urban area (the innercity-Utrecht area and its surrounding authentic quarters, boroughs and outskirts; the town of Maarssen, which is connected to Utrecht by the Utrecht district of Zuilen and the Lage Weide industrial area; Nieuwegein which has grown attached to the south of the city during the seventies and nineties. To which are attached the smaller suburban towns of IJsselstein and Vianen; the former villages of De ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Widnes
Widnes ( ) is an Industrial city, industrial town in the Borough of Halton, Cheshire, England, which at the 2011 United Kingdom census, 2011 census had a population of 61,464. Historic counties of England, Historically in Lancashire, it is on the northern bank of the River Mersey where the estuary narrows to form the Runcorn Gap.

John Hutchinson (industrialist)
John Hutchinson (1825 – 24 March 1865) was a chemist and industrialist who established the first chemical factory in Widnes, Lancashire, England. He moved from working in a chemical factory in St Helens and built his own chemical factory in 1847 in the Woodend area of Widnes near to Widnes Dock by the junction of the Sankey Canal and the River Mersey. In this factory he manufactured alkali by the Leblanc process. He later opened a second alkali factory nearby and developed a number of other business interests. He died at the early age of 40 by which time a number of other chemical factories had opened in the town. Early life The Hutchinson family came from Durham but moved to Liverpool where John was born. His father, John, had held a commission in the Royal Navy and served under Nelson during the Napoleonic Wars. In Liverpool he was a shipbroker and he acted as a Lloyd's agent.

Adolph Wilhelm Hermann Kolbe
Adolph Wilhelm Hermann Kolbe (27 September 1818 – 25 November 1884) was a major contributor to the birth of modern organic chemistry. He was a professor at Marburg and Leipzig. Kolbe was the first to apply the term synthesis in a chemical context, and contributed to the philosophical demise of vitalism through synthesis of the organic substance acetic acid from carbon disulfide, and also contributed to the development of structural theory. This was done via modifications to the idea of "radicals" and accurate prediction of the existence of secondary and tertiary alcohols, and to the emerging array of organic reactions through his Kolbe electrolysis of carboxylate salts, the Kolbe-Schmitt reaction in the preparation of aspirin and the Kolbe nitrile synthesis. After studies with Wöhler and Bunsen, Kolbe was involved with the early internationalization of chemistry through work in London (with Frankland). He was elected to the Royal Swedish Academy of Sciences, and won the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chemistry
Chemistry is the science, scientific study of the properties and behavior of matter. It is a natural science that covers the Chemical element, elements that make up matter to the chemical compound, compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during a Chemical reaction, reaction with other Chemical substance, substances. Chemistry also addresses the nature of chemical bonds in chemical compounds. In the scope of its subject, chemistry occupies an intermediate position between physics and biology. It is sometimes called the central science because it provides a foundation for understanding both Basic research, basic and Applied science, applied scientific disciplines at a fundamental level. For example, chemistry explains aspects of plant growth (botany), the formation of igneous rocks (geology), how atmospheric ozone is formed and how environmental pollutants are degraded (ecology), the properties ...

Metal Carbonyl
Metal carbonyls are coordination complexes of transition metals with carbon monoxide ligands. Metal carbonyls are useful in organic synthesis and as catalysts or catalyst precursors in homogeneous catalysis, such as hydroformylation and Reppe chemistry. In the Mond process, nickel tetracarbonyl is used to produce pure nickel. In organometallic chemistry, metal carbonyls serve as precursors for the preparation of other organometallic complexes. Metal carbonyls are toxic by skin contact, inhalation or ingestion, in part because of their ability to carbonylate hemoglobin to give carboxyhemoglobin, which prevents the binding of oxygen. Nomenclature and terminology The nomenclature of the metal carbonyls depends on the charge of the complex, the number and type of central atoms, and the number and type of ligands and their binding modes. They occur as neutral complexes, as positively-charged metal carbonyl cations or as negatively charged metal carbonylates. The carbon monoxide liga ...
