2-dicyclohexylphospho -2,4, 6-trimethoxybiphenyl (DEDP for short) is an organic phosphorus compound. The following is a description of its nature, use, preparation and safety information:
Nature:
DEDP is a colorless to pale yellow liquid with an aromatic odor similar to benzene. It has low toxicity and vapor pressure, and is soluble in many organic solvents, such as ethanol, ethers, and alkanes. It can evaporate slowly in the air, but is almost insoluble in water.
Use:
DEDP is mainly used as an intermediate for organic phosphorus ester antioxidants and flame retardants. It is often used in the production of products such as rubber, plastics, synthetic textiles, adhesives and paints, which can effectively extend its service life and improve its flame retardant properties.
Preparation Method:
DEDP is mainly prepared by reacting phosphoric anhydride with 2,4, 6-trimethoxybiphenyl. The specific preparation method can be simply summarized as follows: phosphoric anhydride and 2,4, 6-trimethoxybiphenyl are reacted under appropriate reaction conditions, and the DEDP product is obtained through dehydration condensation reaction. After the reaction, purification and purification steps are required to obtain a product with higher purity.
Safety Information:
DEDP has low toxicity, but still needs to be handled properly. During use, necessary protective measures should be taken, such as wearing gloves, goggles and protective clothing. During storage and transportation, DEDP should be kept away from fire sources, heat sources and oxidants, and avoid contact with strong oxidants, acids and alkalis. If you take it by mistake or come into contact with your skin, eyes, or respiratory tract, rinse immediately with plenty of water and seek medical help.
