Ivan Levinstein
Ivan Levinstein (1845-1916) was a German-born British chemist who pioneered the manufacture of synthetic dyes and helped develop the British chemical industry in the late nineteenth century. He was born in Charlottenburg, Germany, the son of a Berlin Calico manufacturer, studied chemistry at the Gewerbeinstitut, which later became the Technical University of Berlin, before joining the family business. He obtained his first patent in Germany in 1863 for improvements in manufacturing coal tar dyes. In 1864 he moved to Blackley, Manchester to start his own chemical manufacturing business. As the business grew it moved to larger premises in Crumpsall, Manchester, in 1887. He developed Rosaline, an artificial magenta dye, Blackley blue dye, Manchester Brown and Manchester Yellow dyes and red azo dyes. He also acted as a spokesperson for the British chemical industry, expressing concerns about growing German competitiveness. He founded, in 1871, the Chemical Review, in 1881 was ...

British Dyestuffs Corporation
British Dyestuffs Corporation Ltd was a British company formed in 1919 from the merger of British Dyes Ltd with Levinstein Ltd. The British Government was the company's largest shareholder, and had two directors on the board. Background By 1913, the Germans had provided 80 percent of the dyes used in Britain. Even the 20% that was produced in the United States was mainly reliant on German intermediates. Stocks of dyes and intermediates were exhausted when World War I broke out in 1914, putting the textile industry in jeopardy. In July 1915, British Dyes, Ltd., was created and bought Read Holliday & Sons of Huddersfield. In 1919, Levinsteins merged with British Dyes, which became the country's largest dyemaker and was renamed the British Dyestuffs Corporation Ltd. BDC supplied a comprehensive range of dyes within a competitive market. Its most notable foreign competitors were Allied Dye & Chemical, Du Pont and IG Farben. It became one of the four British chemical companies wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Imperial Chemical Industries
Imperial Chemical Industries (ICI) was a British chemical company. It was, for much of its history, the largest manufacturer in Britain. It was formed by the merger of four leading British chemical companies in 1926. Its headquarters were at Millbank in London. ICI was a constituent of the FT 30 and later the FTSE 100 indices.

Salford
Salford () is a city and the largest settlement in the City of Salford metropolitan borough in Greater Manchester, England. In 2011, Salford had a population of 103,886. It is also the second and only other city in the metropolitan county after neighbouring Manchester. Salford is located in a meander of the River Irwell which forms part of its boundary with Manchester. The former County Borough of Salford, which also included Broughton, Pendleton and Kersal, was granted city status in 1926. In 1974 the wider Metropolitan Borough of the City of Salford was established with responsibility for a significantly larger region. Historically in Lancashire, Salford was the judicial seat of the ancient hundred of Salfordshire. It was granted a charter by Ranulf de Blondeville, 6th Earl of Chester, in about 1230, making Salford a free borough of greater cultural and commercial importance than its neighbour Manchester..

Blackley
Blackley is a suburban area of Manchester, England. Historically in Lancashire, it is approximately north of Manchester city centre, on the River Irk. History The hamlet of Blackley was mentioned in the Domesday Book. The name derives from the Anglo-Saxon Blæclēah = "dark wood" or "dark clearing". In the 13th and 14th centuries Blackley was referred to as ''Blakeley'' or ''Blakelegh''. By the Middle Ages, Blackley had become a park belonging to the lords of Manchester.' Its value in 1282 was recorded as £6 13s 4d, a sum approximately equivalent in buying power to £333,500 today. The lords of Manchester leased the land from time to time. In 1473, John Byron held the leases on Blackley village, Blackley field and Pillingworth fields at an annual rent of £33 6s 8d. The Byron family continued to hold the land until the beginning of the 17th century when Blackley was sold in parcels to a number of landowners. By the middle of the 17th century, Blackley was a rural village o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Coomassie Brilliant Blue
Coomassie brilliant blue is the name of two similar triphenylmethane dyes that were developed for use in the textile industry but are now commonly used for staining proteins in analytical biochemistry. Coomassie brilliant blue G-250 differs from Coomassie brilliant blue R-250 by the addition of two methyl groups. The name "Coomassie" is a registered trademark of Imperial Chemical Industries. Name and discovery The name Coomassie was adopted at the end of the 19th century as a trade name by the Blackley-based dye manufacturer Levinstein Ltd, in marketing a range of acid wool dyes. In 1896 during the Fourth Anglo–Ashanti War, British forces had occupied the town of Coomassie (modern-day Kumasi in Ghana). In 1918 Levinstein Ltd became part of British Dyestuffs, which in 1926 became part of Imperial Chemical Industries. Although ICI still owns the Coomassie trademark, the company no longer manufactures the dyes. The blue disulfonated triphenylmethane dyes were first produced in ...

Levinstein Process
Mustard gas or sulfur mustard is a chemical compound belonging to a family of cytotoxic and blister agents known as mustard agents. The name ''mustard gas'' is technically incorrect: the substance, when dispersed, is often not actually a gas, but is instead in the form of a fine mist of liquid droplets.https://www.acs.org/content/dam/acsorg/education/resources/highschool/chemmatters/gc-mustard-gas-personal-safety-and-natl-security.pdf Mustard gases form blisters on exposed skin and in the lungs, often resulting in prolonged illness ending in death. The active ingredient in typical mustard gas is the organosulfur compound bis(2-chloroethyl) sulfide. In the wider sense, compounds with the structural element are known as ''sulfur mustards'' and ''nitrogen mustards'', respectively. Such compounds are potent alkylating agents, which can interfere with several biological processes. History as chemical weapons As a chemical weapon, mustard gas was first used in World War I, and has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chemical Companies Of The United Kingdom
A chemical substance is a form of matter having constant chemical composition and characteristic properties. Some references add that chemical substance cannot be separated into its constituent elements by physical separation methods, i.e., without breaking chemical bonds. Chemical substances can be simple substances (substances consisting of a single chemical element), chemical compounds, or alloys. Chemical substances are often called 'pure' to set them apart from mixtures. A common example of a chemical substance is pure water; it has the same properties and the same ratio of hydrogen to oxygen whether it is isolated from a river or made in a laboratory. Other chemical substances commonly encountered in pure form are diamond (carbon), gold, table salt (sodium chloride) and refined sugar (sucrose). However, in practice, no substance is entirely pure, and chemical purity is specified according to the intended use of the chemical. Chemical substances exist as solids, liquids, g ...
