Anwendungen

1,2-Propanediol is used in antifreeze and deicing solutions for cars, boats and aircraft. It is also used to create harmless, artificial smoke for training and theatrical purposes. It is used as a humectant solvent and preservative in food. It acts as a solvent for paints and plastics. Further, it is used in the manufacturing of lactic acid by green catalytic oxidation, propanal and propylene carbonate. It is also employed in veterinary medicine as an oral treatment for hyperketonaemia in ruminants. In addition to this, it reacts with propylene oxide to prepare oligomers.

Bemerkungen

Hygroscopic. Incompatible with acid chlorides, acid anhydrides, oxidizing agents, chloroformates and reducing agents.
