14hexanediol

1,14-Hexadecanediol is a linear diol, meaning it has two hydroxyl (-OH) functional groups at the ends of a 16-carbon chain. Its chemical formula is C16H34O2 and its CAS number is 14743-86-3. It is a solid at room temperature, typically appearing as a white crystalline powder.

This compound finds applications primarily as a building block in the synthesis of various organic molecules. Its long hydrocarbon chain and reactive hydroxyl groups make it suitable for use in the production of polymers, such as polyesters and polyurethanes. These polymers can exhibit unique properties due to the presence of the long, flexible hexadecanediol unit.

1,14-Hexadecanediol can also be utilized in the formulation of lubricants, plasticizers, and surfactants. Its amphiphilic nature, with a hydrophobic hydrocarbon tail and hydrophilic hydroxyl ends, allows it to interact with both polar and nonpolar substances. This characteristic is beneficial in applications where emulsification or surface activity is required.

The synthesis of 1,14-hexadecanediol typically involves reduction reactions of corresponding dicarboxylic acids or diesters, or through other multi-step organic synthesis pathways. Like many diols, it can undergo reactions such as esterification, etherification, and oxidation. Its relatively low volatility and high molecular weight contribute to its stability in various applications.
