PDO is a valuable component for a variety of processes and products
In the chemical industry and manufacturing sphere, 1-3 propanediol, also called trimethylene glycol or 1-3 propylene glycol but more commonly known as PDO, is a valuable component for a variety of processes and products. At Gantrade, we advise customers on the many uses of PDO for multiple industrial applications.
Diols are a subset of molecules known for their usefulness in a multitude of chemical reactions, including the formation of polyesters and polyurethanes, and 1-3 propanediol is no exception. PDO’s high reactivity leads to its use as a primary diol, its use in chain extension reactions for the formation of polyurethanes, and as an intermediate in the formation of polyester polyols.
Traditionally, PDO has been derived from petrochemicals, such as propylene and ethylene glycol. This route makes use of the hydration of acrolein, a toxic petrochemical derivative of propylene, to produce PDO in large quantities.
In recent years, technology has emerged to derive PDO from corn and other biological sources via sugar fermentation, allowing for a smaller ecological footprint and safer manufacturing. In tandem with bio-based succinic and sebacic acids, bio-based 1-3 propanediol can be used to produce 100 percent renewably sourced polyesters.
PDO is a colorless and odorless liquid with a large assortment of useful properties in various applications.
