Linalyl acetate Usage And Synthesis


Beskrivelse

Linalylacetat tilhører monoterpenforbindelse. Det er et naturlig forekommende fytokjemisk funn i mange blomster og krydderplanter. Det er en av hovedkomponentene i essensielle oljer av bergamont og lavendel.1 Det er en klar, fargeløs væske med et kokepunkt på 220 ° C. Kjemisk er det acetatesteren av linalool, og de to forekommer ofte i forbindelse med essensielle oljer av lavendel og lavandin.2
Linalyl acetate is an approved flavoring food additive. It is the most important fragrance ingredient for bergamot, lilac, lavender, linden, neroli, ylang-ylang, and fantasy nots. It is used in decorative cosmetics, fine fragrances, shampoos, toilet soaps and other toiletries as well as in non-cosmetic products such as household cleaners and detergents.3,4

Beskrivelse

Linalyl acetate has a characteristic bergamot-lavender odor and persistent sweet, acrid taste.
Synthesis: Normally prepared by direct acetylation of linalool; another method starts from myrcene hydrochloride, anhydrous sodium acetate, and acetate anhydride in the presence of a catalyst; all synthetic methods tend to avoid the simultaneous formation (because of isomerization) of terpenyl and geranyl acetate.

Kjemiske egenskaper

Linalylacetat har en karakteristisk bergamott - lavendellukt og vedvarende søt, skarp smak.

Kjemiske egenskaper

Klar fargeløs flytende

Kjemiske egenskaper

Linalyl Acetate occurs as its (?) isomer as the main component of lavender oil (30–60%, depending on the origin of the oil), of lavandin oil (25–50%, depending on the species), and of bergamot oil (30–45%). It has also been found in clary sage oil (up to 75%) and in a small amount in many other essential oils. Racemic linalyl acetate is a colorless liquid with a distinct bergamot–lavender odor.
Linalylacetat brukes mye i parfymeri. Det er et utmerket duftmateriale for blant annet bergamott, syrin, lavendel, lind, neroli, ylang-ylang og fantasy notater (spesielt chypre). Mindre mengder brukes i andre sitrusprodukter. Siden linalylacetat er ganske stabilt mot alkali, kan det også brukes i såper og vaskemidler.

Uses

In perfumery.

Contact allergens

Structurally close to linalool, linalyl acetate is the main component of lavender oil and is commonly used in fragrances and toiletries, and in household cleaners and detergents as well. By autoxidation, it leads mainly to hydroperoxides, with a high sensitizing potent.

Chemical Synthesis

Normalt tilberedt ved direkte acetylering av linalool; en annen metode starter fra myrenhydroklorid, vannfritt natriumacetat og acetatanhydrid i nærvær av en katalysator; alle syntetiske metoder har en tendens til å unngå samtidig dannelse (på grunn av isomerisering) av terpenyl og geranylacetat.
