Nature
colorless viscous liquid, leaf-like or rectangular plate-like crystals when solidified. There are sweet flowers. Insoluble in water, water solubility 2.8% (mass). Soluble in acetic acid, ethanol, benzene, petroleum ether, very soluble in ether. In case of high heat, open flame or contact with oxidant, there is a risk of combustion.
Preparation Method
coconut oil as a raw material, in the presence of mixed oxides, by high temperature and high pressure hydrogenation. The mixed alcohols with even number of carbon atoms obtained by the reaction (including low carbon alcohol to octadecanol) are subjected to vacuum fractionation. The Ca ~ Cl2 fraction is refined by boric acid esterification method, and then subjected to vacuum fractionation after hydrolysis, made of nonyl aldehyde, and then reduced to nonyl alcohol, refined by distillation. Alternatively, propylene is polymerized in the presence of phosphoric acid or boron fluoride to give nonene, which is reacted with carbon monoxide and hydrogen in the liquid phase.
Use
for oil drilling and secondary oil recovery, as an additive for oil-based fracturing fluids. Decyl alcohol is also the raw material of polyvinyl chloride wire coating material and high-grade artificial leather plasticizer (DIDP,DIDA), uranium refining, defoaming agent; Surfactant raw material, solvent. In agriculture, it can be used as a solvent and stabilizer for herbicides, pesticides and synthetic raw materials. As a green fruit ripening agent, can also be used for ornamental plants and tobacco and other seed germination control.
Safety
inhalation, ingestion or absorption through the skin is harmful to the body, has a strong stimulating effect, after contact can cause burning sensation, Cough, laryngitis, shortness of breath, Head Pain, Nausea and Vomit. Long contact time can cause anesthetic effect. Staff should be protected. Store in a cool, ventilated room. Keep away from fire and heat source. Keep the container sealed. Should be stored separately from the oxidant. Handling should be light and light unloading, to prevent packaging and container damage.

| Use | n-decyl alcohol is used to make artificial rose oil, orange flower type and Acacia type essence, etc. Also used in the system of lubricating oil additives, plasticizers, adhesives, etc. It is a raw material for the manufacture of surfactants, plasticizers, synthetic fibers, defoamers, herbicides, lubricating oil additives and perfumes, it is also used as a solvent for ink and the like GB 2760-96 is defined as a permitted perfume. Mainly used in the preparation of orange, lemon, coconut and fruit flavor type. trace for Acacia, osmanthus fragrans, violet, red rose, orange flower, yellow narcissus, Iris, clove, Jasmine and sweet orange flower flavor formula. It can be used as a synergic or modifying agent for linalool in low-grade floral-type formulations. Sometimes used in industrial deodorization or to mask the bad breath of industrial products. In the food flavor can also be used in small amounts in cream, orange, coconut, lemon and a variety of fruit aroma. preparation of soap, daily cosmetics flavor. In C8-C18 of the very important position of the alcohol, used in the Rose line flowers fragrant essence. As a citrus fruit flavor, it is used in beverages, sweets, etc. The amounts in food (ppm) were as follows: Ice cream 4.6, Candy 5.2, chewing gum 3.0, beverage 2.1. They should not be used for purposes other than perfuming. Decyl alcohol is also the raw material of polyvinyl chloride wire coating material and high-grade artificial leather plasticizer (DIDP,DIDA), uranium refining, Defoamer, surfactant raw material, solvent. In agriculture, it can be used as a solvent and stabilizer for herbicides, pesticides and synthetic raw materials. As a green fruit ripening agent, can also be used for ornamental plants and tobacco and other seed germination control. It can also be used in oil drilling and secondary oil recovery. used in the production of surfactants, plasticizers and fatty alcohols |
| preparation method | n-decanol is obtained by reduction of coconut oil fatty acids. It can also be obtained from ethylene by controlled polymerization followed by hydrolysis and separation. Naturally occurring: present in sweet orange oil, orange flower oil, apricot flower oil, yellow sunflower seed oil. |
| production method | 1. Natural products are obtained by hydrogenation of coconut oil at high temperature and high pressure in the presence of mixed oxides. The mixed alcohol with even number of carbon atoms (including low carbon alcohol to octadecanol) obtained by the reaction is fractionated under reduced pressure, and the C8-C12 fraction is refined by boric acid esterification method. After hydrolysis, it can also be subjected to carbonylation reaction from nonane, made of nonyl aldehyde, and then reduced to nonyl alcohol, refined by distillation. 2. Polymerization of propylene in the presence of phosphoric acid or boron fluoride to give nonene, which is obtained by reaction of the latter with carbon monoxide and hydrogen in the liquid phase. natural products are obtained by using coconut oil as raw material, under the catalysis of mixed oxides, hydrogenation at high temperature and high pressure, and then fractional distillation under reduced pressure. |
