1-Octanol Chemical Properties,Uses,Production

Chemical properties

Colorless oily liquid; Boiling point 195℃; relative density 0.822-0.830; refractive index 1.428-1.431; flash point 82.5℃; soluble in 5 volumes of 50% ethanol or 3 volumes of 60% ethanol and oil, acid value <1.0. This product has dry sweet and sharp fat wax aroma, and also has citrus, orange peel and rose flavor, like the bottom note of parsnip root creams, the duration time of which is not long. And it also has grease and fruit smell, as well as sweet and slight grass flavor.


1. 1-octanol can be appropriately used in roses, jasmine, lilac, sweet tofu pudding, honey, orange blossom, citrus, parsnip root, cologne, pine needles and other types. And n-octanol can coordinate with roses, ylang-ylang, parsnip root, orange oil and linalool. Trace n-octanol can also be used in edibile peaches, pineapple, coconut, chocolate, citrus and fruit-based flavors.
2. 1-octanol is mainly used in the production of plasticizers, extractants, stabilizers, and also used as solvents and spices intermediates. In the field of plasticizers, octanol is generally referred to 2-ethyl alcohol, which is a megaton bulk raw materials and is more valuable than n-octanol in the industry. Octanol itself is also used as spices, blending roses, lilies and other floral fragrance to make soap perfume. China's GB2760-86 provides for the allowed use of this product for food spices. And it is mainly used to prepare coconut, pineapple, peach, chocolate and citrus flavor.
3. 1-octanol can be used as raw material for perfume, octyl aldehyde, octanoic acid and its ester. It can also be used as solvent, antifoaming agent and lubricating oil additive.
4. Used for the preparation of spices, but also for solvents and antifoaming agents
5. Used as surfactants, solvents, defoamers, industrial additives, etc.
6. Used as solvents, flavoring agents and defoamers. Replace amyl alcohol to reduce ketones in organic synthesis. Used for manufacturing perfume, and also used as gas chromatography analysis standards.

Production methods

Octanol exists in the form of free state or acetate, butyrate and isovalerate esters bitter in orange, grapefruit, sweet orange, green tea, violet leaves and other essential oils. In industrial production, octanol can be obtained by the reduce of octyl aldehyde or the esterification of the octanoic acid in coconut oil. Octanol can also be prepared through carbonyl synthesis with heptene-1 as the raw material. Heptene, carbon monoxide and hydrogen can react in the presence of cobalt salt at 150-170 °C and under high pressure of 20-30MPa to generate aldehyde. After cobalt removal, the above aldehyde is converted into primary alcohol by pressurized hydrogenation with the catalyst of nickel. There has been mature production technology of this method in foreign countries.

Chemical Properties

colourless liquid with a penetrating odour


1-Octanol is an fatty acid alcohol that is used industrially to form various synthetic intermediate and pharmaceuticals.


1-Octanol is a synthetic flavoring agent that is a colorless, stable liquid of sharp fatty odor. it is soluble in alcohol, most fixed oils, mineral oil, and propylene glycol. it should be stored in glass or tin containers. it is used in essential oils for application in beverages, candy, and baked goods at 1–3 ppm. it is also available in the natural form, obtained from natural precursors. it is also termed octyl alcohol.


ChEBI: An octanol carrying the hydroxy group at position 1.

General Description

A clear colorless liquid with a penetrating aromatic odor. Insoluble in water and floats on water. Vapors heavier than air. Vapors may irritate the eyes, nose, and respiratory system.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

Attacks plastics [Handling Chemicals Safely 1980. p. 236]. Acetyl bromide reacts violently with alcohols or water [Merck 11th ed. 1989]. Mixtures of alcohols with concentrated sulfuric acid and strong hydrogen peroxide can cause explosions. Example: an explosion will occur if dimethylbenzylcarbinol is added to 90% hydrogen peroxide then acidified with concentrated sulfuric acid. Mixtures of ethyl alcohol with concentrated hydrogen peroxide form powerful explosives. Mixtures of hydrogen peroxide and 1-phenyl-2-methyl propyl alcohol tend to explode if acidified with 70% sulfuric acid [Chem. Eng. News 45(43):73. 1967; J, Org. Chem. 28:1893. 1963]. Alkyl hypochlorites are violently explosive. They are readily obtained by reacting hypochlorous acid and alcohols either in aqueous solution or mixed aqueous-carbon tetrachloride solutions. Chlorine plus alcohols would similarly yield alkyl hypochlorites. They decompose in the cold and explode on exposure to sunlight or heat. Tertiary hypochlorites are less unstable than secondary or primary hypochlorites [NFPA 491 M. 1991]. Base-catalysed reactions of isocyanates with alcohols should be carried out in inert solvents. Such reactions in the absence of solvents often occur with explosive violence [Wischmeyer 1969].

Health Hazard

Irritates skin and eyes.

Safety Profile

Poison by intravenous route. Moderately toxic by ingestion. Mutation data reported. A skin irritant. Combustible liquid when exposed to heat or flame; can react with oxidizing materials. To fight fire, use water foam, fog, alcohol foam, dry chemical, CO2. See also ALCOHOLS.

Purification Methods

Fractionally distil it under reduced pressure. Dry it with sodium and again fractionally distil or reflux with boric anhydride and re-distilled (b 195-205o/5mm), the distillate being neutralised with NaOH and again fractionally distilled. Also purify it by distillation from Raney nickel and by preparative GLC. [Beilstein 1 IV 1756.]
