Ball and stick model of 1,3-Propanediol

1,3-Propanediol is a chemical compound with the formula C_H_O_. It is a diol, meaning it contains two hydroxyl groups (-OH) attached to a three-carbon alkane chain. This compound is a colorless, odorless, and viscous liquid that is miscible with water.

Chemical Properties

1,3-Propanediol is known for its ability to form strong hydrogen bonds due to the presence of its hydroxyl groups. This property contributes to its high boiling point and solubility in water. The compound is relatively stable but can undergo oxidation to form carboxylic acids.

Production

1,3-Propanediol can be produced through several methods, including the hydration of acrolein and the hydrogenation of acrylic acid. More recently, it has been produced through biotechnological processes using microorganisms such as Escherichia coli that have been genetically modified to convert glucose into 1,3-propanediol.

Applications

1,3-Propanediol is used in the production of polymers, particularly polytrimethylene terephthalate (PTT), which is used in the manufacture of textiles and carpets. It is also used as a solvent, in adhesives, and as an ingredient in cosmetics and personal care products.

Safety and Handling

While 1,3-propanediol is generally considered to be of low toxicity, it should be handled with care. Direct contact with the skin or eyes can cause irritation, and ingestion or inhalation of large quantities can be harmful. Appropriate personal protective equipment should be used when handling this chemical.
