What does chemical engineering do?

Chemical engineering is an abbreviation for "chemical process", "chemical industry", "chemical engineering", etc.

Any technology that uses chemistry to change the composition of a substance or synthesize a new substance is a chemical process.

Any technology that uses chemistry to change the composition or structure of a substance or to synthesize a new substance is a chemical production technology, or chemical process, and the resulting products are called chemicals or chemical products. In the beginning, the production of such products was handmade workshops, which later evolved into factories and gradually formed a specific production industry, namely the chemical industry.

Since the 1960s to 1970s, the chemical industry, the fierce competition among enterprises, on the one hand, due to the reaction process of the in-depth understanding of the production of some traditional basic chemical products can be made, increasingly large-scale production units, in order to reduce costs. At the same time, due to the rise of the new technological revolution, the chemical industry has put forward new requirements, promote the technological progress of the chemical industry, the development of fine chemicals, ultra-pure substances, new structural materials and functional materials.

Chemical development industry development focus - fine chemical industry

Fine chemical industry, including pharmaceuticals, pesticides, synthetic dyes, organic pigments, coatings, fragrances and flavors, cosmetics and toiletries, soaps and synthetic detergents, surfactants, and other chemicals. Synthetic detergents, surfactants, printing inks and their auxiliaries, adhesives, photographic materials, magnetic materials and more than 40 industries and categories. With the development of the national economy, the development and application of fine chemicals will continue to develop, new categories will continue to increase.

Fine chemicals, the term, used for a long time, originally refers to the production of small, high purity, expensive chemical products, such as pharmaceuticals, dyes, paints and so on. However, this meaning has not fully revealed the nature of fine chemicals.

Since the 21st century, experts in various countries have some new insights into the definition of fine chemicals, some countries in Europe and the United States to the yield of small, according to the different chemical structure of the production and sale of chemical substances, known as fine chemicals; to the yield of small, after the processing of the preparation, with a specialized function or end-use performance of the product, known as specialty chemicals. China, Japan and other products of these two categories are collectively referred to as fine chemicals.
