APPLICATION
1,3-propanediol (1,3-PDO) is a colorless, odorless, salty, hygroscopic viscous liquid. It is a raw material for the production of unsaturated polyester, plasticizers, surfactants, emulsifiers and demulsifiers; in the polyurethane industry, it is commonly used as a raw material for polyester polyols, a starter for polyether polyols and a polyurethane extender. Chain agent, etc.; in the organic chemical industry, it is also an important monomer and intermediate. Its main use is as a polymer monomer to synthesize polytrimethylene terephthalate (PrT). It is estimated that by 2020, the potential market capacity of 1,3-propanediol will reach 2.27 million tons.
