504-63-2 - Chemical Properties:

1,3-Propanediol (CAS: 504-63-2), 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.

504-63-2 - Application:

1,3-Propanediol (PDO) (CAS: 504-63-2) is mainly used to produce a new type of polyester polypro/panediol terephthalate (PTT). PTT not only has the chemical stability of polyethylene terephthalate (PET), but also has good resilience and resistance to pollution, so it has a good application prospect in the textile field.
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. Can also be used as antifreeze, emulsifier and other fine chemical raw materials.
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.
Used as organic synthesis, synthesis of various drugs and new antioxidants antifreeze. Solvent. Organic synthesis. Standard for analysis by gas chromatography. It can be used for the synthesis of a variety of drugs, new polyester PTT, pharmaceutical intermediates and new antioxidants. 

504-63-2 - Production Method:

The preparation process of 1,3-Propanediol (PDO) mainly includes three methods: Acrolein hydrate hydrogenation, Ethylene oxide hydroformylation method and biological fermentation. The first two processes are chemical processes, which require a large investment in equipment, high reaction conditions, and serious environmental pollution in the production process. The world's major production enterprises are constantly reducing their capacity. The third process is bioengineering, which has low production cost and green production process. It has gradually replaced chemical method and become the mainstream preparation process in the global 1,3-Propanediol (PDO) industry.
