Module Rationale Industrial chemistry deals with commercial production of chemicals and related products from natural raw materials and their derivatives. It enables humanity to experience the benefits of chemistry when we apply it in the exploitation of materials and energy. When we apply chemistry in the transformation of materials and energy to make useable products, this results in growth and improvement in areas such as food production, health and hygiene, shelter and clothing. The economic growth of industrializedcountriesreliesonthemanufacturingindustryforfinishedproducts.The goalofstudyingindustrialchemistryatuniversityistotryandbridgethegapbetween classical chemistry and chemistry is applied in industry. The chemical industry is highly globalized and produces thousands of chemicals from a wide variety of raw materialsbymeansofvariedtechnologiesforvariedenduses.Itisthereforeimportant to base the study of industrial chemistry on an understanding of the structure of the industry and the unit operations and unit processes that make up the chemical pro-cesses. On the basis of natural raw materials sources and the chemistry involved, we finditeasiertostudyindustrialinorganicandindustrialorganicchemistryseparately, Through the electrolysis of brine, we obtain chlorine and sodium hydroxide both of whichareimportantreactantsinorganicsynthesisofproductssuchaspetrochemicals and detergents respectively. By fixing nitrogen, we obtain ammonia, from which we can make fertilizers. From sulphur, we get sulphuric acid, which we use, in the manufacture of phosphate fertilizers. Mineral ores as well as being raw materials for basic chemicals are the source of pure metals, which we use elsewhere in building and construction, manufacture of equipment, machines and jewellery. Turning now to organic chemical industry, we use petroleum as the source of petrochemicals and syntheticpolymers.Fermentationenablesustoconvertnaturalorganicmaterialsinto chemicals, some like penicillin being pharmaceutical ingredients. From natural oils and fats, we obtain soaps and detergents. ... - tailieumienphi.vn
