Propanediol
Propanediol is a diol, meaning it is an organic compound containing two hydroxyl groups. It exists in three structural isomers: 1,1-propanediol, 1,2-propanediol, and 1,3-propanediol. 1,2-propanediol, also known as propylene glycol, is the most common isomer and is widely used in various industrial and consumer applications.
1,2-propanediol is a clear, colorless, and viscous liquid with a faint, sweet odor. It is miscible with
1,3-propanediol is another significant isomer. It can be produced through petroleum-based routes or via bio-based fermentation
The safety and environmental impact of propanediol isomers vary depending on the specific isomer and its application.
