Henry Hennell
Henry Hennell FRS (''c.'' 1797 – 4 June 1842) was an English chemist. Hennelll was one of the founders of the Chemical Society of London and was a member of the first elected Council of the Chemical Society. He was elected F.R.S. in 1829. He worked as Chemical Operator at Apothecaries' Hall, London. In 1825 Michael Faraday discovered that sulfuric acid could absorb large volumes of coal gas. He gave the resulting solution to Hennell, who found in 1826 that it contained "sulphovinic acid" ( ethyl hydrogen sulfate). Hennell's finding was a major breakthrough in the synthesis of ethanol Ethanol (also called ethyl alcohol, grain alcohol, drinking alcohol, or simply alcohol) is an organic compound with the chemical formula . It is an Alcohol (chemistry), alcohol, with its formula also written as , or EtOH, where Et is the ps ... and led to major developments in organic chemistry.

Chemical Society Of London
The Chemical Society was a scientific society formed in 1841 (then named the Chemical Society of London) by 77 scientists as a result of increased interest in scientific matters. Chemist Robert Warington was the driving force behind its creation. The London Chemical Society 1824 The early days of the 1824 Chemical Society came with a rough start. Among the artisan class, the magazine ''The Chemist'', written by John Knight and Henry Lacey, had started to get some traction. Some argue that they falsely mentioned that the 1824 Chemical Society was attempting to gather an educated upper and middle-class group of chemists and philosophers. Because of this, the writers of ''The Chemist'' maintained a very practical and anti-theoretical bias, as they had lashed out at the time wasted by academic chemists researching atomic weight distributions. To find a means of how this society should be better set up and run, correspondents and proponents of ''The Chemist'' advised that membership i ...

Apothecaries' Hall, London
Apothecaries Hall is a scheduled monument at Black Friars Lane, London. It is the headquarters of the Worshipful Society of Apothecaries of London, one of the livery companies of the City of London. It is one of the largest livery companies (with over 1,600 members in 2012) and ranks 58th in their order of precedence. The building, originally part of the Dominican priory of Black Friars, was called Cobham House prior to its purchase by the society in 1632. The original building was destroyed in the Great Fire of London in 1666, although a significant extent of the 13th-century buildings remain, including a portion of the walls, now incorporated into the north range of the hall courtyard. A new hall was built on the same site and footprint of rooms, and completed in 1672 to the design of Edward Jerman; an "Elaboratory" was included at this time for the first-ever large-scale manufacture of drugs. From then until 1922, the society manufactured medicinal and pharmaceutical prod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Michael Faraday
Michael Faraday (; 22 September 1791 – 25 August 1867) was an English chemist and physicist who contributed to the study of electrochemistry and electromagnetism. His main discoveries include the principles underlying electromagnetic induction, diamagnetism, and electrolysis. Although Faraday received little formal education, as a self-made man, he was one of the most influential scientists in history. It was by his research on the magnetic field around a Electrical conductor, conductor carrying a direct current that Faraday established the concept of the electromagnetic field in physics. Faraday also established that magnetism could Faraday effect, affect rays of light and that there was an underlying relationship between the two phenomena. the 1911 ''Encyclopædia Britannica''. He similarly discovered the principles of electromagnetic induction, diamagnetism, and the Faraday's laws of electrolysis, laws of electrolysis. His inventions of electric motor, electromagnetic rotar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sulfuric Acid
Sulfuric acid (American spelling and the preferred IUPAC name) or sulphuric acid (English in the Commonwealth of Nations, Commonwealth spelling), known in antiquity as oil of vitriol, is a mineral acid composed of the elements sulfur, oxygen, and hydrogen, with the molecular formula . It is a colorless, odorless, and Viscosity, viscous liquid that is Miscibility, miscible with water. Pure sulfuric acid does not occur naturally due to its Dehydration reaction, strong affinity to water vapor; it is Hygroscopy, hygroscopic and readily absorbs water vapor from the Atmosphere of Earth, air. Concentrated sulfuric acid is a strong oxidant with powerful dehydrating properties, making it highly corrosive towards other materials, from rocks to metals. Phosphorus pentoxide is a notable exception in that it is not dehydrated by sulfuric acid but, to the contrary, dehydrates sulfuric acid to sulfur trioxide. Upon addition of sulfuric acid to water, a considerable amount of heat is releas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coal Gas
Coal gas is a flammable gaseous fuel made from coal and supplied to the user via a piped distribution system. It is produced when coal is heated strongly in the absence of air. Town gas is a more general term referring to manufactured gaseous fuels produced for sale to consumers and municipalities. The original coal gas was produced by the coal gasification reaction, and the burnable component consisted of a mixture of carbon monoxide and hydrogen in roughly equal quantities by volume. Thus, coal gas is highly toxicity, toxic. Other compositions contain additional Calorific Value, calorific gases such as methane, produced by the Fischer–Tropsch process, and volatile hydrocarbons together with small quantities of non-calorific gases such as carbon dioxide and nitrogen. Prior to the development of natural gas supply and transmission—during the 1940s and 1950s in the United States and during the late 1960s and 1970s in the United Kingdom and Australia—almost all gas for fu ...

Ethyl Sulfate
Ethyl sulfate (IUPAC name: ethyl hydrogen sulfate), also known as sulfovinic acid, is an organic chemical compound used as an intermediate in the production of ethanol from ethylene. It is the ethyl ester of sulfuric acid. History This substance was studied contemporaneously with ether by German alchemist August Siegmund Frobenius in 1730, subsequently by French chemists Fourcroy in 1797 and Gay-Lussac in 1815. Swiss scientist Nicolas-Théodore de Saussure also studied it in 1807. In 1827, French chemist and pharmacist Félix-Polydore Boullay (1806-1835) along with Jean-Baptiste André Dumas noted the role of ethyl sulfate in the preparation of diethyl ether from sulfuric acid and ethanol. Further studies by the German chemist Eilhard Mitscherlich and the Swedish chemist Jöns Berzelius suggested sulfuric acid was acting as a catalyst, this eventually led to the discovery of sulfovinic acid as an intermediate in the process. The advent of electrochemistry by Italian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ethanol
Ethanol (also called ethyl alcohol, grain alcohol, drinking alcohol, or simply alcohol) is an organic compound with the chemical formula . It is an Alcohol (chemistry), alcohol, with its formula also written as , or EtOH, where Et is the pseudoelement symbol for ethyl group, ethyl. Ethanol is a Volatility (chemistry), volatile, flammable, colorless liquid with a characteristic wine-like odor and pungent taste. As a psychoactive depressant, it is the active ingredient in alcoholic beverages, and the second most consumed drug globally behind caffeine. Ethanol is naturally produced by the fermentation process of sugars by yeasts or via petrochemical processes such as ethylene hydration. Historically it was used as a general anesthetic, and has modern medical applications as an antiseptic, disinfectant, solvent for some medications, and antidote for methanol poisoning and ethylene glycol poisoning. It is used as a chemical solvent and in the Chemical synthesis, synthesis of orga ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Humphry Davy
Sir Humphry Davy, 1st Baronet (17 December 177829 May 1829) was a British chemist and inventor who invented the Davy lamp and a very early form of arc lamp. He is also remembered for isolating, by using electricity, several Chemical element, elements for the first time: potassium and sodium in 1807 and calcium, strontium, barium, magnesium and boron the following year, as well as for discovering the elemental nature of chlorine and iodine. Davy also studied the forces involved in these separations, inventing the new field of electrochemistry. Davy is also credited with discovering clathrate hydrates. In 1799, he experimented with nitrous oxide and was astonished at how it made him laugh. He nicknamed it "laughing gas" and wrote about its potential as an Anesthesia, anaesthetic to relieve pain during surgery. Davy was a baronet, President of the Royal Society (PRS), Member of the Royal Irish Academy (MRIA), a founder member and Fellow of the Geological Society of London, and a ...

William Thomas Brande
William Thomas Brande FRS FRSE (11 January 178811 February 1866) was an English chemist. Biography Brande was born in Arlington Street, London, England, the youngest son of six children to Augustus Everard Brande an apothecary, originally from Hanover in Germany. He was educated first in Kensington and then in Westminster. After leaving Westminster School, he was apprenticed, in 1802, to his brother, an apothecary, with the view of adopting the profession of medicine. He studied medicine at Great Windmill Street Medical School and at St George's Hospital, before being drawn to chemistry following a meeting with Humphry Davy. He then began to lecture in chemistry, based on a sound knowledge of which he acquired in his spare time. In 1811 he published the first of what were to be two very influential articles on the measurement of alcohol in fermented drinks, including wine, cider and ale. Until that point chemists had only been able to measure alcohol in distilled drinks (b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
East India Company
The East India Company (EIC) was an English, and later British, joint-stock company that was founded in 1600 and dissolved in 1874. It was formed to Indian Ocean trade, trade in the Indian Ocean region, initially with the East Indies (South Asia and Southeast Asia), and later with East Asia. The company gained Company rule in India, control of large parts of the Indian subcontinent and British Hong Kong, Hong Kong. At its peak, the company was the largest corporation in the world by various measures and had its own armed forces in the form of the company's three presidency armies, totalling about 260,000 soldiers, twice the size of the British Army at certain times. Originally Chartered company, chartered as the "Governor and Company of Merchants of London Trading into the East-Indies," the company rose to account for half of the world's trade during the mid-1700s and early 1800s, particularly in basic commodities including cotton, silk, indigo dye, sugar, salt, spices, Potass ...

Union Street, London
Union Street is a major street in the London Borough of Southwark. It runs between Blackfriars Road to the west and Borough High Street to the east. Southwark Bridge Road crosses in the middle. History The eastern part of the street was laid out under a 1774 Act passed for making a new workhouse and for "making a carriage way from the … High Street, through the Greyhound Inn, into Queen Street, and for improving the passage from thence into Gravel Lane, leading towards the Black Friars Bridge Road, in the parish of Christ Church." In 1782 the Union Hall was opened as the Surrey Magistrates Court in the borough, the JPs having previously sat at the Town Hall in the High Street. The façade of the Hall was retained on the new structure on the site in 2005. In 1813, Queen Street and Duke Street were renamed Union Street. In 1908 Charlotte Street, at the western end of Union Street, was also renamed to be part of the street yet it clearly has a dislocated junction with it, ex ...
