1,4-Pentanediol

Description:

1,4-Pentanediol, with the CAS number 626-95-9, is a linear aliphatic diol characterized by its two hydroxyl (-OH) functional groups located at the first and fourth carbon atoms of a five-carbon chain. This compound is a colorless, viscous liquid at room temperature and has a mild, sweet odor. It is hygroscopic, meaning it can absorb moisture from the air, and is soluble in water as well as in many organic solvents, making it versatile in various applications. 1,4-Pentanediol is commonly used as a building block in the synthesis of polymers, plasticizers, and surfactants, and it serves as a solvent in chemical processes. Its low toxicity and biodegradability enhance its appeal in industrial applications. Additionally, it has a relatively high boiling point and a moderate flash point, indicating that it should be handled with care to avoid fire hazards. Overall, 1,4-Pentanediol is valued for its functional properties in both chemical synthesis and formulation.

1,4-Pentanediol is a diol that is used in the manufacture of polyurethanes and other organic compounds. It is produced by the oxidation of benzene with oxygen in the presence of a catalyst such as manganese dioxide. 1,4-Pentanediol can also be prepared from levulinic acid or glycol ethers. 1,4-Pentanediol reacts with an aromatic hydrocarbon in the presence of a homogeneous catalyst to produce viscosity and polycarboxylic acids. The reaction mechanism for this process begins with the addition of water to form hydrogen peroxide and acetaldehyde. Hydrogen peroxide then reacts with an aromatic hydrocarbon to produce glycol ether and hydroxy group. The hydroxyl group then reacts with another aromatic hydrocarbon to produce viscosity and polycarboxylic acid. The reaction products are isolated by distillation or vacuum evaporation, after which they are purified by recrystall
