Pentadecane-olid 15 , also 1.15 pentadecanolide or exaltolide is a macrocyclic (16-membered) lactone and is among the musk fragrances .
Occurrence
Pentadecan-15-olide is a component of the oil from angelica ( angelica ). It was identified in medicinal angelica oil by Max Kerschbaum von Haarmann & Reimer in the 1920s .
Manufacturing
When 15-bromopentadecanoic acid is heated with potassium carbonate or from 15-hydroxypentadenanoic acid and benzenesulfochloride , pentadecan-15-olide is formed with cyclization. It can also be obtained by hydrogenating 15-pentadecenolide . It is usually present as a mixture of 15-pentadecen-11-olide and 15-pentadecen-12-olide. This double bond isomer mixture is referred to in the present case as 15-pentadecene-11 (12) -olide.
use
Pentadecan-15-olide is a monomer used to make PGA-co-pentadecalactone polymers, which are used in the development of directly compressed, extended-release tablets of poorly soluble drugs such as ketoprofen . Pentadecan-15-olide can also be used for the synthesis of poly (pentadecanolide) (PPDL) by Novozyme 435 catalyzed ring-opening polymerization. It can also be used as a starting reagent for the synthesis of terminally branched iso-fatty acids (iso-C15-C17).
Pentadecan-15-olide can in particular also be used as a fragrance , in perfume compositions, perfume oils or fragrance compositions. Another area of use is hygiene or care products, particularly in the household and personal care sector.
