What is 10-UNDECEN-1-OL?

Chemical properties

Colourless liquid. Soluble in 70% alcohol. Combustible.

Chemical properties

10-Undecen-1-ol is a colorless liquid with a fatty, green, slightly citrus-like odor. It can be synthesized from 10-undecylenic acid and is used to give flower perfumes a fresh note.

Occurrence

Reported found in distilled essential oil from leaves of Litsea odorifera Valeton. Also reported found in grilled and roasted beef.

The Uses of 10-UNDECEN-1-OL

10-Undecen-1-ol is used as a flavoring agent. It reacts with tosylated beta-cyclodextrin to prepare beta-cyclodextrin undecenylether. It is used in the synthesis of 10-Undecenylacrylat by reacting with acryloyl and triethylamine. It reacts with carbon monoxide in the presence of dicobalt octacarbonyl and pyridine as a base at pressures greater than 150 bar and temperatures in the range of 100 to 2000C to linear and branched polyesters having relatively high molecular weights (Mn> 10,000 g / mol) in good yields.

The Uses of 10-UNDECEN-1-OL

Perfumes.

Definition

ChEBI: An alkenyl alcohol that is 1-undecene in which one of the terminal methyl hydrogens is replaced by a hydroxy group.

Preparation

Prepared from coconut fatty acids as starting material.
