Diphenylphosphine is a commonly used organic phosphorus compound, which is widely used in chemical industry. It has good reducibility and electrophilicity, and is often used as a reducing agent and catalyst. However, due to its toxicity and flammability, extreme care is required during use. The following are some things to pay attention to when using diphenylphosphine:
Keep the
1. well ventilated
When using diphenylphosphine, ensure that the operating place is well ventilated. Should try to operate in a well-ventilated place to avoid long-term inhalation of its vapor.

used in a confined environment should wear a gas mask and protective gloves to prevent inhalation or contact with diphenylphosphine.

2. avoid contact with oxygen or water
contact of diphenylphosphine with oxygen or water will produce toxic phosphine gas, and even cause explosion in severe cases. Therefore, care should be taken to avoid contact with air or water, store in a dry place, and keep away from open flames and heat sources.

3. the correct storage of
diphenylphosphine in storage away from oxidants, acids and so on. Store in a cool, dry, ventilated place, avoid direct sunlight.

should be stored in isolation from flammable and combustible materials to prevent fire accidents.

4. Avoid direct contact with skin and eyes
diphenylphosphine is a toxic substance. Avoid direct contact with skin and eyes when using it. Once in contact, rinse with plenty of water immediately and seek medical treatment in time.

5. to properly dispose of waste
After the use of diphenylphosphine waste to be properly disposed of, can not be directly discarded into the trash can. The classification and disposal shall be carried out in accordance with the requirements of relevant laws and regulations to avoid pollution to the environment.

through the above points of attention, we can use diphenylphosphine more safely to avoid accidents. In chemical production, safety is the first priority. I hope every practitioner can strictly abide by the relevant safety operation procedures to ensure the safety and smooth progress of the work.
