Read： 529 Time：12months ago Source：Transform the World with Simplicity

Isophthalyl ether is an important raw material for chemical production, which is widely used in medicine, pesticide, dye and other fields. Due to its flammable and toxic properties, it is necessary to strictly comply with relevant regulations during storage and transportation to ensure safety. This article will detail the safety storage and transportation specifications of m-phthalide.

1. the physical and chemical properties of m-phthalide

m-phthalide is a colorless and transparent liquid with a pungent odor. Its molecular formula is C8H10O2 and its molecular weight is 138.17. Isophthalyl ether is insoluble in water, but is miscible with organic solvents such as alcohols and ethers. It has a melting point of -25°C, a boiling point of 197°C and a flash point of 73°C. Isophthalyl ether is a flammable and toxic substance, which may cause combustion and explosion when exposed to open flame, high heat or oxidant.

2. isophthalic ether risk overview

isophthalic ether has certain harm to the human body, mainly through the respiratory tract, skin and digestive tract into the human body, can cause toxic hepatitis, nephritis, neuritis and other diseases. In addition, m-phenylene ether is also flammable and may cause combustion and explosion when exposed to open flame, high heat or oxidant. Therefore, during storage and transportation, special attention needs to be paid to its safety.

3. isophthalic ether storage specification

1. The storage place should choose a cool, ventilated and dry place, away from open flame, heat source and oxidant.
2. The storage container shall be a special container with good sealing performance to avoid leakage and volatilization.
3. The storage area shall be provided with obvious safety warning signs, and equipped with corresponding fire-fighting equipment and leakage emergency treatment equipment.
4. During the storage process, the safety status of containers and storage areas should be checked regularly, and any abnormalities should be handled in time.

4. m-phthalic ether transport specifications

1. Transport vehicles should have the appropriate qualifications and certificates, transport personnel should be professionally trained and obtain the appropriate qualification certificate.
2. During transportation, the container shall be sealed to avoid leakage and volatilization. At the same time, it should be kept away from open flames, high heat and oxidants.
3. During transportation, the vehicle speed should be strictly controlled to avoid sudden braking and severe vibration to prevent container damage.
4. Transportation vehicles shall be equipped with corresponding fire-fighting equipment and leakage emergency treatment equipment to deal with emergencies.

for leakage of
5. m-phthalide
1. if m-phthalide leakage occurs, the leakage source should be cut off immediately, and special absorption materials should be used to absorb and treat the leakage.
2. During the treatment, open flame, high heat and oxidant should be avoided to prevent combustion and explosion.
3. If the leakage is large, it should be reported to the local environmental protection department immediately and disposed of in accordance with relevant regulations.

In short, as an important raw material for chemical production, its safety and stability are of great significance to ensure the smooth progress of the production process. Therefore, in the process of storage and transportation, relevant regulations must be strictly observed to ensure safety. At the same time, the safety education and training of employees should be strengthened to improve safety awareness and ensure the effective implementation of various safety measures.
