3. Exists in flue-cured tobacco leaves.
4. Naturally found in sweet orange oil and other essential oils.
Storage method
Stored sealed in a cool, dry place. Make sure the workspace has good ventilation. Keep away from sources of fire. Store away from oxidizing agents. Can be stored in iron, mild steel, copper or aluminum containers.
Generally, iron drums are used, and large quantities can be transported by tank trucks. Refined products can be packaged in glass bottles or iron cans. The storage tank should be grounded and use a flame arrester to prevent fire. It is advisable to protect yourself from the sun and stay away from fire and heat sources. Store and transport according to general chemical regulations.
Synthesis method
1. Natural products are made from coconut oil as raw material and are obtained by hydrogenation under high temperature and high pressure in the presence of mixed oxides. The even-numbered carbon-atom mixed alcohols (including low-carbon alcohols to octadecyl alcohols) obtained by the reaction are fractionated under reduced pressure. The C8-C12 fraction is refined by boric acid esterification. After hydrolysis, it is fractionated under reduced pressure. It can also be carbonylated from nonane. Nonaldehyde is made, then reduced to nonanol, and distilled and refined.
2. Propylene in phosphoric acid or fluorine Nonene is polymerized in the presence of boron to obtain nonene, which is obtained by reacting with carbon monoxide and hydrogen in the liquid phase.
Purpose
1. Prepare soap and daily cosmetics essence. It occupies a very important position among C8-C18 alcohols and is used in rose floral essences. As a citrus fruit flavor, it is used in beverages, candies, etc. The dosage (ppm) in food is as follows: ice cream 4.6, candy 5.2, chewing gum 3.0, and beverage 2.1. May not be used for purposes other than fragrance. Decanol is also a raw material for polyvinyl chloride wire covering materials and plasticizers (DIDP, DIDA) for high-grade artificial leather, uranium refining, defoaming agents, surfactants, and solvents. In agriculture, it can be used as a solvent and stabilizer for herbicides, pesticides and synthetic raw materials. It is used as a ripening agent for green fruits and can also be used to control the germination of ornamental plants and tobacco seeds. It can also be used in oil drilling and secondary oil recovery.
