13086-84-5 - Introduction
Di-tert-butyl phosphite (BPDP) is an organic phosphate compound. The following is a description of its nature, use, preparation and safety information:
Nature:
Di-tert-butyl phosphite is a colorless liquid with a low boiling point and flash point. It is insoluble in water at normal temperature and can be dissolved in organic solvents such as alcohols and ethers. The compound has good thermal stability and chemical stability.
Use:
Di-tert-butyl phosphite is mainly used as an additive for flame retardants and plasticizers in industry. It can increase the softness, cold brittleness and heat resistance of the plastic. In addition, di-tert-butyl phosphite can also be used as a light stabilizer, which plays a role in anti-ultraviolet aging in polymer and rubber products.
Preparation Method:
The preparation of di-tert-butyl phosphite usually adopts transesterification reaction. Specifically, tri (diisopropyl) tris (tert-butoxy) phosphate is reacted with diethyluronyl alcohol to produce di-tert-butyl phosphite by transesterification.
Safety Information:
The use of di-tert-butyl phosphite requires caution. It can be harmful to humans and the environment. Contact with di-tert-butyl phosphite may cause irritation and allergic reactions, so skin contact and inhalation should be avoided during use. At the same time, we should pay attention to prevent its leakage and diffusion, so as not to cause pollution to the environment. Appropriate protective measures, such as gloves, goggles and protective clothing, are required during operation.
