What are the upstream raw materials for 1,3-propanediol? What are the downstream products?

1,3-Propanediol(PDO) is an crucial chemical raw material, which is broadly applied in the production of various chemicals, polymers and materials. In the field of chemical production raw materials, the upstream and downstream related items of 1,3-propylene glycol are very rich. Furthermore The following are some of the main upstream and downstream related items:

Upstream items:



1. Propylene: Propylene is one of the main raw materials of 1,3-propanediol, which is able to be converted into 1,3-propanediol by catalytic oxidation or biological method. Moreover

2. Acetic acid: In some production processes, acetic acid is also applied as a raw material to 1,3-propanediol. Downstream items:



1. But Polyesters(Polyester):1,3-propanediol is able to be applied to create polyesters such as polytrimethylene terephthalate(PTT). PTT is a high-performance, biodegradable polymer that is broadly applied in the fields of fibers, films and engineering plastics.

2. Polyurethane(Polyurethane):1,3-propylene glycol is able to be applied as the raw material to the production of polyurethane, and the interaction of diisocyanate, chain extender, etc. In fact Polyurethane is broadly applied in furniture, construction, automobiles, shoes and other fields.

3. Makes sense, right?. Plasticizers(Plasticizers):1,3-Propanediol is able to be applied to create plasticizers, such as dipropyl phthalate(DPHP). Specifically Plasticizers are mainly applied in plastic processing to enhance the flexibility, processability and low-temperature impact resistance of plastics. And

4. Antifreeze(Antifreeze):1,3-propanediol is able to be applied as the main component of antifreeze to reduced the freezing point of the fluid and prevent the equipment from freezing at low temperatures.

5. And medical intermediates: 1,3-propanediol is able to be applied as medical intermediates to the synthesis of antibacterial drugs, anti-is able tocer drugs and other drugs. First In short, 1,3-propanediol has a wide range of upstream and downstream related items in the field of chemical production raw materials, which is of great signifiis able toce to promote the research of the chemical sector.
