This 3-carbon diol is a colorless viscous liquid that is miscible with water. It is soluble in many common organic solvents, except benzene, carbon tetrachloride, diethyl ether, methyl isobutyl ketone, and nitromethane.Weast, Robert C. (1973). "Miscibility of Organic Solvent Pairs". CRC Handbook of Chemistry and Physics (54th ed.). Ohio, USA: CRC Press. page C-720. Products It is mainly used as a building block in the production of polymers such as polytrimethylene terephthalate.Propanediols Carl J. Sullivan Anja Kuenz Klaus-Dieter Vorlop 2018 10.1002/14356007.a22_163.pub2 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. Production 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. Two other routes involve bioprocessing by certain micro-organisms: Conversion from glucose effected by a genetically modified strain of E. coli by DuPont Tate & Lyle BioProducts (See: bioseparation of 1,3-propanediol). An estimated 120,000 tons were produced in 2007".Werle Peter Alcohols, Polyhydric 2008-07-15 https://onlinelibrary.wiley.com/doi/10.1002/14356007.a01_305.pub2 Ullmann's Encyclopedia of Industrial Chemistry a01_305.pub2 Wiley-VCH Verlag GmbH & Co.
