Read： 667 Time：20months ago Source：Transform the World with Simplicity

In the field of chemical production raw materials, 3,4-dichloroaniline is an important organic compound, which is widely used in pesticides, pharmaceuticals, dyes and other industries. However, due to its toxicity and corrosiveness, it may cause harm to humans and the environment. Therefore, it is necessary to strictly abide by relevant regulations during storage and transportation to ensure safety.

This article will detail the safety storage and transportation specifications of 3,4-dichloroaniline to ensure safety in the production process.

1. the physical and chemical properties of 3,4-dichloroaniline

3,4-dichloroaniline is a white to light yellow crystalline powder with a melting point of 82-85 ℃ and a boiling point of 246 ℃. It is insoluble in water and soluble in alcohol, ether and other organic solvents. The compound is stable to light, heat and air, but may decompose at high temperatures to produce toxic gases.

2. safety storage specifications

1. Storage facilities: 3,4-dichloroaniline should be stored in a cool, dry, well-ventilated special warehouse, away from fire, heat and direct sunlight. The warehouse floor should be flat, non-slip, and with anti-leakage measures.
2. Storage container: 3,4-dichloroaniline should be stored in a container with good sealing performance to ensure that the container does not leak gas or liquid. The container shall be marked with the compound name, danger and safety precautions.
3. Storage management: A strict storage management system should be established to keep detailed records of 3,4-dichloroaniline's warehousing, outbound and storage, and make regular inventory to ensure that the accounts are consistent.

3. safety transport specification

1. transport vehicles: special vehicles with dangerous goods transport qualification shall be used for transport, and the vehicles shall be equipped with corresponding fire-fighting equipment and leakage emergency treatment equipment.
2. Transport packaging: The packaging of 3,4-dichloroaniline should meet relevant national standards and have sufficient strength to withstand vibration and impact during transportation. Packaging should be tight, moisture-proof, leak-proof, and indicate the compound name, danger and safety precautions.
3. Transportation route: Choose a safe transportation route and avoid crossing densely populated areas and environmentally sensitive areas as much as possible. During transportation, the vehicle speed shall be kept stable, and behaviors such as sudden braking and sharp turning shall be avoided.

4. safety operation specification

1. personnel protection: operators should be professionally trained to understand the physical and chemical properties of 3,4-dichloroaniline and safety operation procedures. Personal protective equipment such as protective gloves and masks should be worn during operation to avoid direct contact with compounds.
2. Operating environment: The operating site should be well ventilated to ensure air circulation. Safety warning signs shall be set up in the operation area to prohibit open fire and smoking.
3. operation steps: in strict accordance with the operating procedures to operate, to ensure that the feeding, reaction, discharge and other steps are accurate. In case of abnormal conditions during operation, the operation shall be stopped immediately and corresponding measures shall be taken.

5. emergency treatment measures

1. Leakage treatment: in case of leakage accident of 3,4-dichloroaniline, emergency plan shall be started immediately, effective measures shall be taken to prevent the leakage from spreading, and the leakage area shall be cleaned and disinfected.
2. Poisoning treatment: if any person is poisoned, the poisoned person shall be immediately moved to a safe area, and first aid measures shall be taken and sent to the hospital for treatment.

In conclusion, in the field of chemical production raw materials, the safe storage and transportation of 3,4-dichloroaniline is very important. By strictly abiding by relevant norms and taking effective protective measures and emergency treatment measures, the harm of compounds to human body can be reduced and the safety in the production process can be guaranteed.
