1,3-프로판디올 C화학적 특성, 용도, 생산
화학적 성질
1,3-Propanediol, an isomer of propylene glycol, is a viscous, colorless, odorless, hygroscopic liquid that has a brackish irritating taste. miscible with various solvents such as water, ethanol, acetone, chloroform (chloroform) and ether, and is insoluble in benzene. Combustible.용도
As a diol, 1,3-propanediol is subject to many of the same polymeric applications as other low molecular mass diols (e.g., ethylene glycol, propylene glycol, and 1,4-butanediol). However, its relatively high price limits its use to applications requiring very specific performance characteristics. It is a raw-material source for 1,3-dioxanes. 1,3-Propanediol-bis(4-aminobenzoate) can be used as a chain extender in polyurethane elastomers. This bisbenzoate, which can also be synthesized from 1,3-dichloro-propane, finds other applications as a cross-linking agent in epoxy formulations and as a rubber additive.정의
ChEBI: Propane-1,3-diol is the simplest member of the class of propane-1,3-diols, consisting of propane in which one hydrogen from each methyl group is substituted by a hydroxy group. A colourless, viscous, water-miscible liquid with a high (210℃) boiling point, it is used in the synthesis of certain polymers and as a solvent and antifreeze. It has a role as a protic solvent and a metabolite.주요 응용
In adipate polyesters with other diols these diols are partly substituted by 1,3-propanediol (PDO) to break crystallinity in order to obtain liquid polyester polyols. In polyesters for powder coatings PDO improves the flexibility but lowers the glass transition temperature somewhat. PDO finds also uses in cosmetics and personal care products, engine coolants, and solvents for ink-jet and screen inks.주요 응용
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. It is also used to Solvent for thin film preparations, Vinyl epoxide synthon and reagent for epoxide ring-opening and polymerization reactions, Reagent for natural product syntheses.A new large market for 1,3-propanediol will be in polyester coatings and in the production of poly(trimethylene terephthalate), a new material for the production of high quality carpet fibers.
Biosynthesis
1,3-Propanediol (1,3-PDO) can be produced by fermentation from glycerol, with different strains such as Klebsiella pneumoniae, Clostridium butyricum, Clostridium pasteurianum, and Citrobacter freundii. Drawbacks of industrial fermentation using these strains are strong inhibition of 1,3-PDO production and by-products during fermentation.Synthesis
1,3-Propanediol is produced commercially by Degussa starting from acrolein.CH2CHCHO + H2O → HOHCH2CH2CHO
HOHCH2CH2CHO + H2 → HOHCH2CH2CH2OH
The addition of water under mild acidic conditions gives 3-hydroxypropionaldehyde with high selectivity. Preferentially buffer solutions with a pH 4-5 or weak acidic ion exchange resins are used as catalysts. Further hydrogenation of this aqueous solutions gives 1,3-propanediol. There is an alternative route via hydroformylation of ethylene oxide and subsequent hydrogenation of the intermediate 3-hydroxypropionaldehyde.
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.]1,3-프로판디올 준비 용품 및 원자재
