1,3-Propanediol Chemical Properties,Uses,Production

Chemical Properties

Colorless oil liquid; odorless. Soluble in water, alcohol, and ether. Combustible.

Chemical Properties

1,3-Propanediol, an isomer of propylene glycol, is a viscous, colorless, odorless, hygroscopic liquid that has a brackish irritating taste .

Uses

1,3-Propanediol is prepared as a by-product in the manufacture of glycerin by the saponification of fat . It is used to lower the freezing point of water and as a chemical intermediate. Industrial exposure is limited.

Uses

1,3-Propanediol is used as a solvent for thin film preparations, in the production of polymers such as polytrimethylene terephthalate, adhesives, laminates, coatings, moldings, aliphatic polyesters, as an antifreeze and in wood paint. It also acts as a reagent for vinyl epoxide synthon, for epoxide ring-opening, for polymerization reactions and for natural product syntheses.

Uses

Solvent for thin film preparations.1 Vinyl epoxide synthon2 and reagent for epoxide ring-opening3 and polymerization reactions.4 Reagent for natural product syntheses.5

Purification Methods

Dry this diol with K2CO3 and distil it under reduced pressure. More extensive purification involves conversion with benzaldehyde to 2-phenyl-1,3-dioxane (m 47-48o) which is subsequently decomposed by shaking with 0.5M HCl (3mL/g) for 15minutes and standing overnight at room temperature. After neutralisation with K2CO3, the benzaldehyde is removed by steam distillation and the diol is recovered from the remaining aqueous solution by continuous extraction with CHCl3 for 1day. The extract is dried with K2CO3, the CHCl3 is evaporated and the diol is distilled. [Foster et al. Tetrahedron 6 177 1961, Beilstein 1 IV 2493.]
