Malic acid in the field of chemical production of raw materials in the safety of storage and transport norms

1. Introduction

Malic acid as an important chemical production of raw materials, widely used in food, medicine, cosmetics and other fields. In order to ensure the safety of malic acid during storage and transportation, this article will introduce its related standard operations in detail.

2. the physical and chemical properties of malic acid

malic acid is an organic acid with strong acidity and corrosion. It is generally a white crystalline powder, readily soluble in water, ethanol and ether. At high temperatures, malic acid easily decomposes, producing carbon dioxide and water. Therefore, special attention should be paid to its properties during storage and transportation.

3. malic acid storage specifications

1. Storage environment: Malic acid should be stored in a dry, cool, well-ventilated place, avoid direct sunlight and high temperature.
2. Storage container: Malic acid should be stored in a corrosion-resistant container to avoid corrosion of the container.
3. Storage identification: The name, purity, production date and service life of malic acid should be marked in the storage container.

4. malic acid transportation specifications

1. Transportation vehicles: Special vehicles with anti-corrosion and leak-proof functions should be used for transportation to ensure that there is no leakage during transportation.
2. Transport personnel: transport personnel should be professionally trained to understand the nature of malic acid and transport precautions.
3. Transportation identification: the name, risk level and transportation precautions of malic acid shall be marked on the transportation vehicle.

5. malic acid safety operation specification

1. operators: operators should be professionally trained to understand the nature of malic acid and safety precautions.
2. Operating environment: The operation should be carried out in a well-ventilated environment to avoid excessive malic acid gas concentration.
3. Operation protection: Operators should wear protective gloves, goggles and other personal protective equipment to avoid direct contact with malic acid.

6. malic acid emergency treatment specification

1. skin contact: such as malic acid contact with the skin, should immediately rinse with plenty of water, and seek medical treatment.
2. Eye contact: If malic acid comes into contact with eyes, rinse immediately with plenty of water and seek medical attention.
3. Inhalation: If malic acid gas is inhaled, immediately leave the scene to a fresh air place, keep the respiratory tract unobstructed, and seek medical treatment.
4. Leakage treatment: In case of malic acid leakage, measures should be taken immediately to prevent the leakage from spreading, collecting and recycling or transporting to the waste treatment site for disposal. Summary of

7.

Malic acid is an important raw material for chemical production, and its safe storage and transportation are very important. By understanding its physical and chemical properties, strictly complying with storage, transportation and safe operation specifications, and mastering emergency treatment methods, the safety of malic acid in the production and use process can be effectively guaranteed, and accidents and losses caused by improper operation can be avoided.
