The safe storage and transportation specification
of methyl acetate
Methyl acetate, also known as methyl acetate, is a colorless transparent liquid with a special fragrance. It is widely used as a raw material in the fields of chemical industry, food and medicine. However, methyl acetate has flammable, explosive and toxic properties, so during storage and transportation, relevant safety regulations must be strictly observed.

1. the physical and chemical properties of methyl acetate

methyl acetate molecular formula is C3H6O2, molecular weight is 74.08, density is 0.932g/cm3, melting point is -98 ℃, boiling point is 57.2 ℃. It is poorly soluble in water, but is miscible with organic solvents such as alcohols and ethers. After the vapor of methyl acetate is mixed with air, it can form an explosive mixture, and the explosion limit is 4%-15% (volume ratio).

2. the hazardous
of methyl acetate
methyl acetate is less toxic to humans, but long-term exposure may cause damage to the nervous system and digestive system. Methyl acetate is also irritating and narcotic, and exposure to high concentrations may cause human poisoning. In addition, methyl acetate is also flammable and explosive, and may cause combustion and explosion when exposed to open flame, high heat or oxidant.

3. methyl acetate safe storage specification

1. storage place should be selected in a cool, well-ventilated, away from the fire. The storage temperature should not exceed 30 ℃, and the relative humidity should be kept below 75%.
2. The storage container must be well sealed to prevent leakage of methyl acetate. The storage container shall be subject to regular safety inspection and maintenance to ensure the integrity of the container.
3. The storage site shall be equipped with corresponding fire-fighting equipment and leakage emergency treatment equipment for use in emergency situations.
4. Avoid mixing with oxidants, acids, alkali metals and other items during storage.
Safety transportation specifications for
4. methyl acetate

1. Before transportation, check the safety and tightness of the transportation vehicle to ensure that the vehicle will not leak during transportation.
2. During transportation, the vehicle speed should be kept stable, and operations such as sudden braking and sharp turns should be avoided to reduce impact and vibration during transportation.
3. Transport vehicles shall be equipped with corresponding fire fighting equipment and leakage emergency treatment equipment for use in emergency situations.
4. During transportation, high temperature and open fire environment should be avoided to prevent methyl acetate from burning and exploding.

5. methyl acetate leakage emergency treatment

1. In case of methyl acetate leakage accident, the emergency plan should be started immediately, and personnel should be organized to evacuate and rescue.
2. For small spills, sand, dry lime or soda ash can be mixed and recycled. For large spills, special pumps shall be used to recycle the spills into special containers.
3. When dealing with leakage, personal protective equipment such as protective gloves and face masks should be used to avoid direct contact with methyl acetate.

In short, methyl acetate is an important raw material for chemical production, and its safe storage and transportation are very important. In the process of storage and transportation, the relevant safety regulations should be strictly observed, and the training of management and operators should be strengthened to ensure the safe use of methyl acetate.
