colorless oily liquid. With ethanol, ether and chloroform miscible, insoluble in water.
octanol is present in essential oils such as bitter orange, grapefruit, sweet orange, green tea, Violet Leaf, etc., either in a free state, or in an acetate, butyrate, isovalerate. In industrial production, octanal can be reduced or octanoic acid present in coconut oil can be used to prepare each. It can also be obtained by a carbonyl synthesis method using heptene-1 as a raw material. Heptene and carbon monoxide and hydrogen in the presence of cobalt salt, at 150,170 deg C and 20~30MPa high pressure to produce aldehyde, after cobalt removal, and then nickel catalyst pressure hydrogenation into primary alcohol.
used as an additive for oil-based fracturing fluids. It is also used in the production of plasticizers, extractants, stabilizers, as intermediates for solvents and perfumes. Octanol itself is also used as a spice, blending rose, lily and other floral essences, as soap spices.

application | octanol, also known as n-octanol, is an organic compound, colorless and transparent oily liquid, with strong grease smell and citrus flavor, not miscible with water, but miscible with ethanol, ether and chloroform. Octanol is mainly used to prepare dioctyl phthalate, dioctyl terephthalate, octyl acrylate, dioctyl azelate, dioctyl sebacate and other products; in addition, it can also be used as solvent, Plasticizer, antifreeze, lubricant, extractant, dispersant, stabilizer, perfume and other products are used in refined oil, plastics, coatings, printing and dyeing, food processing, cosmetics and other fields. Octanol is mainly used to produce plasticizers, extractants, stabilizers, and intermediates for solvents and fragrances. In the field of plasticizers, octanol generally refers to 2-ethylethanol, which is a bulk raw material of one million tons and is far more valuable in industry than n-octanol. Octanol itself is also used as a spice, blending roses, lilies and other floral flavors, as a soap spice. This product is a edible spice allowed by the GB2760-86 regulations of our country. It is mainly used to prepare coconut, pineapple, peach, chocolate and citrus essence. |
use | can be used in an appropriate amount of rose, jasmine, lilac, sweet bean flower, honey fragrance, orange blossom, citrus, parsnip root, cologne, pine needles, etc. It can be coordinated with rose, ylang ylang, parsnip root, orange oil and linalool. It can also be used in trace amounts of peaches, pineapples, coconuts, chocolate, various citrus and fruit-based flavors. It is mainly used to produce plasticizers, extractants, stabilizers, and intermediates for solvents and fragrances. In the field of plasticizers, octanol generally refers to 2-ethylethanol, which is a bulk raw material of one million tons and is far more valuable in industry than n-octanol. Octanol itself is also used as a spice, blending roses, lilies and other floral flavors, as a soap spice. This product is a edible spice that is allowed to be used according to the GB2760-86 regulations of our country. Mainly used to prepare coconut, pineapple, peach, chocolate and citrus flavors. It can be used as a raw material for fragrances, octopaldehyde, caprylic acid and its esters, as well as as solvents, defoamers and lubricating oil additives It is used for the preparation of fragrances, as well as solvents and anti-foaming agents. Used as surfactants, solvents, defoamers, industrial additives, etc. Solvents, flavoring agents, defoamers, organic synthesis, instead of pentanol to reduce ketones, manufacturing fragrances, gas chromatography analysis standards. |
production method | octanol exists in the free state of essential oils such as bitter orange, pomelo, sweet orange, green tea, violet leaves, or in the form of acetate, butyrate and isovalerate. In industrial production, octanal can be reduced or prepared by using the octanoic acid present in coconut oil. It can also be obtained by carbonyl synthesis with hepten-1 as raw material. In the presence of cobalt salt, heptene, carbon monoxide and hydrogen generate aldehydes at 150-170 ℃ and 20-30MPa. After cobalt removal, they are pressurized and hydrogenated into primary alcohols with nickel catalyst. The law has a mature production process abroad. |
