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. |

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. |
