By the 1920s, chemical firms consolidated into large conglomerates ; IG Farben in Germany, Rhône-Poulenc in France and Imperial Chemical Industries in Britain. Dupont became a major chemicals firm in the early 20th century in America. Polymers and plastics such as polyethylene , polypropylene , polyvinyl chloride , polyethylene terephthalate , polystyrene and polycarbonate comprise about 80% of

192-558: A plant in Charleroi Belgium. In 1874, they expanded into a larger plant in Nancy , France. The new process proved more economical and less polluting than the Leblanc method, and its use spread. In the same year, Ludwig Mond visited Solvay to acquire the rights to use his process, and he and John Brunner formed Brunner, Mond & Co. , and built a Solvay plant at Winnington , England. Mond

240-630: A site separate from the production plant(s). The scale of chemical manufacturing tends to be organized from largest in volume ( petrochemicals and commodity chemicals ), to specialty chemicals , and the smallest, fine chemicals . The petrochemical and commodity chemical manufacturing units are on the whole single product continuous processing plants. Not all petrochemical or commodity chemical materials are made in one single location, but groups of related materials often are to induce industrial symbiosis as well as material, energy and utility efficiency and other economies of scale . Those chemicals made on

288-579: A wide variety of solid, liquid, and gaseous materials. Most of these products serve to manufacture other items, although a smaller number go directly to consumers. Solvents , pesticides , lye , washing soda , and portland cement provide a few examples of products used by consumers. The industry includes manufacturers of inorganic - and organic -industrial chemicals, ceramic products, petrochemicals, agrochemicals, polymers and rubber (elastomers), oleochemicals (oils, fats, and waxes), explosives, fragrances and flavors. Examples of these products are shown in

Ammonium sulphate fertiliser, asphalt road surfacing , coke oil and coke were later added to the product line. The late 19th century saw an explosion in both the quantity of production and the variety of chemicals that were manufactured. Large chemical industries arose in Germany and later in

432-573: The Mountain Rescue Committee and president of the Rucksack Club . Fellow climber, Frank Solari , praised Hartley in his obituary for Alpine Journal , His personal qualities were of the highest. Able to converse on many subjects, he knew when to appreciate silence. Under intolerable weather conditions he never lost his head or temper. His natural courtesy avoided offence when his intellect forced him to disagree with others. On rock he

480-451: The first pieces of environmental legislation to be passed in 1863. This provided for close inspection of the factories and imposed heavy fines on those exceeding the limits on pollution. Methods were devised to make useful byproducts from the alkali. The Solvay process was developed by the Belgian industrial chemist Ernest Solvay in 1861. In 1864, Solvay and his brother Alfred constructed

528-585: The raw materials . Later a plant (of his own) was in operation producing 320 tons of soda ash per year. The process, however, is now obsolete and is superseded by the Solvay process . Two years later the plant was confiscated by the French revolutionary government, which refused to pay him the prize money he had earned ten years earlier. In 1802 Napoleon returned the plant (but not the prize) to him, but by then Leblanc could not afford to run it. He committed suicide by

576-791: The $ 546 billion global specialty chemical market was 33% Paints, Coating and Surface Treatments, 27% Advanced Polymer, 14% Adhesives and Sealants, 13% additives, and 13% pigments and inks. Speciality chemicals are sold as effect or performance chemicals. Sometimes they are mixtures of formulations, unlike " fine chemicals ," which are almost always single-molecule products. Consumer products include direct product sales of chemicals such as soaps , detergents , and cosmetics . Typical growth rates are 0.8 to 1.0 times GDP. Consumers rarely come into contact with basic chemicals. Polymers and specialty chemicals are materials that they encounter everywhere daily. Examples are plastics, cleaning materials, cosmetics, paints & coatings, electronics, automobiles and

624-540: The 1840s. The first synthetic dye was discovered by William Henry Perkin in London . He partly transformed aniline into a crude mixture which, when extracted with alcohol, produced a substance with an intense purple colour. He also developed the first synthetic perfumes. German industry quickly began to dominate the field of synthetic dyes. The three major firms BASF , Bayer , and Hoechst produced several hundred different dyes. By 1913, German industries produced almost 90% of

672-576: The EU and U.S. chemical companies are the world's largest producers. Sales of the chemical business can be divided into a few broad categories, including basic chemicals (about 35% - 37% of dollar output), life sciences (30%), specialty chemicals (20% - 25%) and consumer products (about 10%). Basic chemicals, or "commodity chemicals" are a broad chemical category including polymers, bulk petrochemicals and intermediates, other derivatives and basic industrials, inorganic chemicals , and fertilizers . Polymers are

720-518: The European Chemical industry saw its sales increase from 295 billion Euros to 539 billion Euros, a picture of constant growth. Despite this, the European industry's share of the world chemical market has fallen from 36% to 20%. This has resulted from the huge increase in production and sales in emerging markets like India and China. The data suggest that 95% of this impact is from China alone. In 2012

768-784: The Food and Drug Administration. Pesticides, also called "crop protection chemicals", are about 10% of this category and include herbicides , insecticides , and fungicides . Specialty chemicals are a category of relatively high-valued, rapidly growing chemicals with diverse end product markets. Typical growth rates are one to three times GDP with prices over a dollar per pound. They are generally characterized by their innovative aspects. Products are sold for what they can do rather than for what chemicals they contain. Products include electronic chemicals, industrial gases , adhesives and sealants as well as coatings, industrial and institutional cleaning chemicals, and catalysts. In 2012, excluding fine chemicals,
