undecanol

Undecanol, also known as hendecanol or undecyl alcohol, is a straight-chain fatty alcohol with the chemical formula CH3(CH2)10OH. It is a saturated alcohol containing eleven carbon atoms. At room temperature, undecanol is a colorless liquid or a waxy solid, depending on its purity and specific isomer. It has a characteristic fatty, waxy odor.

Undecanol is sparingly soluble in water but soluble in organic solvents such as ethanol and ether. It is produced through various chemical processes, often starting from fatty acids or their derivatives. One common method involves the reduction of undecanoic acid. It can also be synthesized through Ziegler alcohol synthesis or by hydroformylation of undecene followed by hydrogenation.

In terms of applications, undecanol is used as a precursor in the synthesis of various chemicals. It is employed in the production of plasticizers, lubricants, and surfactants. Its esters can be used as fragrances and flavorings in the cosmetic and food industries. Due to its long hydrocarbon chain, it can also find use in certain specialty solvents and as a component in some biodegradable polymers. Undecanol is generally considered to have low toxicity, but like many alcohols, it can be irritating to skin and eyes.
