1,3-Propanediol, also propane-1,3-diol or trimethylene glycol, is a three-carbon diol. It is a clear colorless viscous liquid that is miscible with water and ethanol.[1]
1,3-Propanediol can be formulated into a variety of industrial products including composites, adhesives, laminates, coatings, moldings, novel aliphatic polyesters, copolyesters, solvents, antifreeze and other end uses.
1,3-Propanediol does not appear to pose a significant hazard via inhalation of either the vapor or a vapor/aerosol mixture.[2]

Production
1,3-Propanediol may be prepared via various routes:[3]
- Hydration of acrolein, followed by reduction
- Hydroformylation of ethylene oxide
- fermentation of glycerol
- Aldol condensation of formaldehyde and acetaldehyde, followed by hydrogenation
Currently 1,3-propanediol is being produced with genetically modified strain of E. coli fed a refined corn syrup by Dupont Tate & Lyle Bioproducts.citation needed
