Read： 787 Time：14months ago Source：Transform the World with Simplicity

Phthalic anhydride (phthalic anhydride) is a common chemical raw material, widely used in plastics, resins, coatings, pharmaceuticals and other fields. Due to its certain toxicity and corrosiveness, it is necessary to strictly comply with relevant safety regulations during storage and transportation.

1. Phthalic Anhydride Hazard Overview

Phthalic Anhydride is a colorless or slightly yellow crystalline powder with a high melting point and boiling point. It has a certain toxicity and irritation to the human body, can cause skin and eye irritation and allergies, long-term contact may also lead to chronic poisoning. In addition, phthalic anhydride is also corrosive and has a certain corrosive effect on metal containers and pipes.

2. phthalic anhydride storage specification

1. The storage place should be dry, ventilated, cool, and avoid direct sunlight and high temperature.
2. The storage container should be made of corrosion-resistant materials, such as stainless steel or glass fiber reinforced plastic.
3. The storage area should be kept away from fire source, heat source and oxidant, and it is forbidden to mix with alkaline substances and food.
4. During storage, the tightness and integrity of the container should be checked regularly to prevent leakage and contamination.

3. phthalic anhydride transport specification

1. should check the packaging is intact before transport, if there is damage should be dealt with in a timely manner.
2. During transportation, it should be kept stable to avoid violent vibration and collision.
3. The transport vehicles shall have the functions of sun protection, rain protection and leakage prevention to ensure the safety of transportation.
4. During transportation, relevant laws, regulations and regulations shall be observed to ensure legal compliance.

4. phthalic anhydride safety operation specification

1. operators should undergo professional training, understand the nature of phthalic anhydride and safe operation procedures.
2. Before operation, check whether the equipment, containers and pipelines are in good condition, and deal with any damage in time.
3. Wear protective gloves, goggles and other personal protective equipment during operation to avoid direct contact with phthalic anhydride.
4. Good ventilation should be maintained during operation to avoid high concentration of phthalic anhydride vapor.
5. In case of leakage and other accidents, measures shall be taken immediately to avoid environmental pollution.

5. phthalic anhydride waste disposal specification

1. waste phthalic anhydride should be in accordance with the relevant regulations and standards for processing, to avoid pollution to the environment.
2. The waste phthalic anhydride can be disposed by incineration, chemical treatment, etc., but it should be ensured that no secondary pollution will occur during the treatment process.

In short, phthalic anhydride, as a common raw material for chemical production, needs to strictly abide by relevant safety regulations during storage, transportation and operation to ensure personnel safety and environmental protection. At the same time, the waste phthalic anhydride also needs to be processed in compliance to avoid environmental pollution.
