This product is colorless transparent liquid; There was a slight ether odor. Acetonitrile is mainly used as a solvent. Such as the extraction of butadiene solvent, synthetic fiber solvent and some special coatings solvent. Used in the petroleum industry to remove tar from petroleum hydrocarbons; A solvent for substances such as phenols. It can be used as solvent to extract fatty acid from driven vegetable oil in oil industry and as reaction medium for recrystallization of steroid drugs in medicine. Binary azeotropic mixtures of acetonitrile and water are often used when polar solvents with high dielectric constants are required: acetonitrile 84%, boiling point 76℃. Acetonitrile is the intermediate of medicine and spice, and is the raw material for the manufacture of nitrogenous fertilizer synergist. Also used as a denaturing agent for alcohol.
Acetonitrile is a toxic, flammable colorless transparent liquid, so in the process of transportation must pay attention to safety. Acetonitrile transport vehicles should be equipped with the corresponding variety and quantity of fire fighting equipment and leakage emergency treatment equipment. Try to transport in the morning and evening in summer. The trough (tank) car used in transportation should have a grounding chain, and the groove can be equipped with a hole partition to reduce the shock generated static electricity. It is strictly forbidden to mix and transport with oxidizer, reducing agent, acid, alkali, combustible or combustible, edible chemicals and so on.
During transportation, it should be protected from sun exposure, rain and high temperature. When the vehicle in the stopover, should be far away from fire, heat source, high temperature area. The exhaust pipe of the vehicle carrying the goods shall be equipped with fire retardant device. Mechanical equipment and tools that are easy to produce sparks are prohibited to be loaded and unloaded. Road transportation should follow the prescribed route, do not stay in residential and densely populated areas. Slip away should be forbidden in railway transportation. It is strictly prohibited to transport in bulk by wooden vessel or cement vessel.
Tightly sealed, to provide sufficient local exhaust and full ventilation. The operation is mechanized and automated as far as possible. Operators need to be specially trained and strictly abide by the operating procedures. It is recommended that the operator wear a filter gas mask (full face mask), self-contained breathing apparatus or ventilated breathing apparatus, rubber anti-toxic clothing and rubber oil-resistant gloves. Keep away from fire and heat source. No smoking in workplace. Use explosion-proof ventilation systems and equipment. Keep away from flammable and combustible materials. Prevent steam leakage into the workplace air. Avoid contact with oxidants, reducing agents, acids and bases. Handling should be carried lightly to prevent damage to packaging and containers. Equipped with the corresponding variety and quantity of fire fighting equipment and leakage emergency treatment equipment. Empty containers may contain hazardous materials.
