Chemical compound

1,3-Propanediol is the organic compound with the formula CH2(CH2OH)2. This 3-carbon diol is a colorless viscous liquid that is miscible with water.

It is mainly used as a building block in the production of polymers such as polytrimethylene terephthalate.[2]

1,3-Propanediol can be formulated into a variety of industrial products including composites, adhesives, laminates, coatings, moldings, aliphatic polyesters, and copolyesters. It is also a common solvent. It is used as an antifreeze and as a component in wood paint.

1,3-Propanediol is mainly produced by the hydration of acrolein. An alternative route involves the hydroformylation of ethylene oxide to form 3-hydroxypropionaldehyde. The aldehyde is subsequently hydrogenated to give 1,3-propanediol. Biotechnological routes are also known.[2]

Two other routes involve bioprocessing by certain micro-organisms:

1,3-Propanediol does not appear to pose a significant hazard via inhalation of either the vapor or a vapor/aerosol mixture.[7]
