Security Information
Storage precautions: Store in a cool, ventilated warehouse. 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.
