Fine chemical industry is one of the most dynamic emerging field of chemical industry, is an important part of the new material. Fine chemical products variety, high added value and wide application, the industrial connection, direct service industries of national economy and the areas of high and new technology industry. Developing fine chemical industry has become the world countries to adjust the structure of chemical industry and energy chemical industry industry and expand the economic benefits of strategic focus. Rate of fine chemical industry, fine chemical industry output value proportion of the total output value of chemical) of high and low has become a measure of a country or region developed chemical industry and chemical industry science and technology level of important symbol. The following is introduce simple fine chemical industry development.
Fine icbc industry emerged in the early 20th century to the postwar 60 ~ 70 s, with the constant progress of science and technology more and more varieties, dye, since the invention of the reactive dyes, dye and fiber combined by chemical bonds. Synthetic fiber and its blended fabric need new dyes, such as disperse dyes for polyester, used for acrylic cationic dye, reactive disperse dyes for polyester/cotton blended. In addition, there are used in laser, liquid crystal, and other special dye microscopy techniques. 40 s in terms of pesticide, f. h. miller, Switzerland invented the first organochlorine pesticide DDT, and developed a series of organochlorine, organophosphorus pesticides, the latter has the stomach to kill, tag, and other special effects. Insist on high-efficiency, later or no residues of pesticides, such as biomimetic synthesis method for the strain. Consciousness in the '60 s, fungicide, and herbicide is fast, there have been some performance good varieties, such as pyridine herbicide, benzene and imidazole fungicide, etc. In addition, pesticides and antibiotics, such as China in 1976 developed into jinggangmeisu for resistance to rice sheath blight. Medicine, in 1910 the French p. Ehrlich made 606 arsenic preparation (after the antidote to cure mumefural), and made improvements in the structure of the 914 s, 30 s sulphonamide compounds, steroide, etc from the structure improvement, play a role of the special effects.
