1-Nonanol Usage And Synthesis

Description

1-Nonanol is a straight chain fatty alcohol with nine carbon atoms and the molecular formula CH3(CH2)8OH. It is a colorless to slightly yellow liquid with a citrus odor similar to citronella oil. Nonanol occurs naturally in the orange oil. The primary use of nonanol is in the manufacture of artificial lemon oil. Various esters of nonanol, such as nonyl acetate, are used in perfumery and flavors. Nonanol floats on water and its freezing point 23°F.

Toxicity

1-Nonanol shares similar toxicological properties to those of other primary alcohols. It is poorly absorbed through the skin and is severely irritating to the eyes. Vapors can be damaging to the lungs, causing pulmonary edema in severe cases. Oral exposure results in symptoms similar to those of ethanol intoxication, and like ethanol consumption, can cause liver damage.

Metabolism of action

Nonanol, like other primary alcohols, undergoes two general reactions in vivo. The first is oxidation to the carboxylic acid derivative and next the direct conjugation with glucuronic acid. It was reported that nonanol undergoes direct glucuronic conjugation to the extent of 4.1%. This oxidation proceeds with very little inhibition as opposed to that shown by methyl amyl alcohol and 2-ethyl butyl alcohol which form ester glucuronides.

Methods of Manufacturing

Made by sodium or high-pressure catalytic reduction of esters of pelargonic acid; hydroformylation of C8 linear alpha-olefins or internal olefins (occurs in a mixt); natural constituent of rose, grapefruit & orange oils.

Description

Nonyl alcohol has a characteristic rose-orange odor and a slightly fatty, bitter taste reminiscent of orange. May be synthesized by reduction of ethyl pelargonate; from heptaldehyde via heptanol and heptylmagnesium bromide with ethylene oxide.

Chemical Properties

Nonyl alcohol has a characteristic rose–orange odor and a slightly fatty, bitter taste reminiscent of orange.

Chemical Properties

colourless to light yellow liquid

Chemical Properties

1-Nonanol is found in a number of citrus oils. It is a liquid.

Occurrence

Reported as occurring frequently in nature, free or esterified; in the essential oils of grapefruit, Guinea sweet orange, Italian and Israeli sweet orange, bitter orange; and in oak musk concrete. Also reported found in apple, citrus juices, many berries, currants, guava, grapes, papaya, melon, pineapple, asparagus, cucumber, leek, peas, potato, cheeses, butter, milk, cooked chicken, beef and pork, hop oil, beer, rum, grape wines, tea, pecan, peanut oil, soybean, olive, plum, rose apple, beans, mushroom, starfruit, cauliflower, tamarind, fig, cardamom, rice, prickly pear, sweet corn, malt, cherimoya, clary sage, oysters, crab, crayfish, clam, nectarine, mate, pepino fruit (Solanum muricatum), apricot, tobacco, and wheat bread.

Uses

1-Nonanol is an chain fatty acid alcohol that naturally occurs in oil of orange. 1-Nonanol is used in the manufacture of artificial lemon oil.

Uses

In manufacture of artificial lemon oil.

Preparation

By reduction of ethyl pelargonate; from heptaldehyde via heptanol and heptylmagnesium bromide with ethylene oxide.

Production Methods

1-Nonanol is produced by the high-pressure catalytic reduction of esters of pelargonic acid.

Aroma threshold values

Detection: 50 to 90 ppb; aroma characteristics at 1.0%: intensely waxy, sweet, green, citrus, orange-like, creamy with fruity nuances of tamarind and melon.

Taste threshold values

Taste characteristics at 0.5 to 1.0 ppm: waxy, green, coconut, cheese, milky and creamy with citrus orange nuances.

General Description

Colorless liquid with a rose or fruity odor. Floats on water. Freezing point 23°F.

Reactivity Profile

1-Nonanol is an alcohol. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert them to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides.

Health Hazard

Liquid irritates eyes.

Chemical Reactivity

Reactivity with Water: No reaction; Reactivity with Common Materials: No reaction; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.

Safety Profile

Mddly toxic by ingestion, skin contact, and inhalation. Experimental reproductive effects. Combustible liquid. When heated to decomposition it emits acrid smoke and irritating fumes. See also ALCOHOLS.

Metabolism
