The Development Of The Chemical Industry
Soon after the Middle Ages, factories supplying soaps, alums, acids and other basic chemicals grew. In 1749, the Lead Chamber process for the commercial manufacture of hydrogentetraoxosulphate (VI) was developed. This initiated a whole new range of the chemical industries. Later in 1791, the Lebanc process for the making of trioxocarbonate(IV) was invented. Extensive industrial chemical research, however, was not in full swing until 1856 when Willian Perkin discovered the first aniline dye. Then, research by teams of scientists became the norm in chemical industry. chemical industry Now in our society, you will see the raw materials used and how they are converted into the various products that are in great demand.
The chemical industry produces a variety of products, it is useful to classify the industry base on its products. We have chemical industries which produce
* chemical products used as starting materials in other industries that manufacture substances such as fertilizer, paints and explosives;
* basic chemicals such as aids, alkalis salts and organic chemicals;
*chemical products that are used in the manufacture of artificial fibres and plastics; and
*Chemical products such as cosmetics, drugs and soap for our personal use.
The fertilizer industry, for instance, is an important one. Fertilizers are needed to increase crop yield to feed the world’s rapidly increasing population.
There are three important elements that must be provided in suitable form in fertilizer production. They are NITROGEN, PHOSPHORUS and POTASSIUM (commonly referred to as N.P.K.) There are different sources to get these important elements of fertilizer production.
Nitrogen is supplied in the form of ‘ammonia’. Ammonia is obtained from fuel such as coal or oil that was formed over millions of years from the remains of animals or plants – fossil fuels.
