Acetonitrile is an organic compound with the molecular formula CH3CN or c2h3n. It is a colorless liquid, highly volatile, with a special smell similar to ether, excellent solvent performance, and can dissolve a variety of organic, inorganic and gaseous substances. It has certain toxicity and is infinitely miscible with water and alcohol. Acetonitrile is an important organic intermediate, which can undergo typical nitrile reactions and is used to prepare many typical nitrogen-containing compounds. Acetonitrile can be used as a solvent for the synthesis of vitamin A, cortisone, carboamine drugs and their intermediates, and also as an active medium solvent for the manufacture of vitamin B1 and amino acids. It can replace chlorinated solvent. It is used in vinyl coating, fatty acid extractant, alcohol denaturant, butadiene extractant and solvent of acrylonitrile synthetic fiber. It is also used in fabric dyeing, lighting, perfume manufacturing and photosensitive material manufacturing.
Chemical analysis and instrumental analysis
Acetonitrile is an organic modifier and solvent used in thin layer chromatography, paper chromatography, spectroscopy and polarographic analysis in recent years. Since high-purity acetonitrile does not absorb ultraviolet light at 200nm ~ 400nm, an application being developed is as a solvent for high-performance liquid chromatography HPLC, which can make the analytical sensitivity as high as 10-9 levels.
Intermediate of synthetic medicine and pesticide
Acetonitrile can be used as an intermediate in the synthesis of various medicines and pesticides. In medicine, it is used to synthesize a series of important pharmaceutical intermediates, such as vitamin B1, metronidazole, ethambutol, aminopteridine, adenine and antitussive; In pesticides, it is used to synthesize pyrethroid insecticides, acetaminophen and other pesticide intermediates.
Semiconductor cleaning agent
Acetonitrile is an organic solvent with strong polarity. It has good solubility in grease, inorganic salt, organic matter and polymer compounds. It can clean grease, wax, fingerprints, corrosive agent and flux residues on silicon wafers. Therefore, high purity acetonitrile can be used as semiconductor cleaner.

Keep away from fire and heat sources. The storage temperature should not exceed 30°C. Keep the container tightly closed. It should be stored separately from oxidizers, reducing agents, acids, alkalis, combustibles, and edible chemicals, and avoid mixed storage. Use explosion-proof lighting and ventilation facilities. It is forbidden to use mechanical equipment and tools that are prone to sparks. The storage area should be equipped with leakage emergency treatment equipment and suitable storage materials. Application The main purpose of acetonitrile is as a solvent. For example, as a solvent for extracting butadiene, a solvent for synthetic fibers and a solvent for some special coatings. Used in the petroleum industry to remove tar, phenol and other solvents from petroleum hydrocarbons. In the oil industry, it is used as a solvent for extracting fatty acids from animal and vegetable oils, and as a reaction medium for the recrystallization of steroid drugs in medicine. When a polar solvent with a high dielectric constant is required, a binary azeotropic mixture of acetonitrile and water is often used. Acetonitrile is an intermediate of medicine (vitamin B1) and spices, and a raw material for the manufacture of s-triazine nitrogen fertilizer synergist. It is also used as a denaturant for alcohol. In addition, it can also be used to synthesize ethylamine, acetic acid, etc., and also have many uses in textile dyeing and electronics industry. Acetonitrile is also used as a mobile phase solvent in analytical equipment such as chromatography.
