| use | used as paint desiccant, plasticizer and synthetic lubricant GB 2760-96 stipulates that it is allowed to use edible spices. Mainly used to prepare coconut and berry flavors. Organic synthesis raw materials, oxidation can produce azelaic acid, ammonia hydrogenation can produce nonamine, pressure hydrogenation can produce nonanol. Nonanoic acid is also used in the production of nonanoic acid esters plasticizers and also as a paint desiccant. Nonanoic acid has light fat and coconut aroma. China's GB2760-86 regulations are allowed to use edible spices, mainly used to prepare coconut and berry flavors. An intermediate for the production of detergent bleaching activators, used to produce polyol esters as lubricants for fibers and jet turbines. Organic synthesis. Organic synthetic raw materials, oxidation can be made into azelaic acid, ammoniation can be made into nonylamine, pressure hydrogenation can be made into nonyl alcohol, but also can be used to produce nonyl acid ester plasticizers and so on. |
| production method | the natural product (free or esterified state) exists in essential oils such as rose, geranium, iris, hops, lavender, etc. Industrially obtained by oxidation of 1-octene or oleic acid. 1. Oleic acid is oxidized by nitric acid or ozone. 2. Using 1-octene and synthesis gas as raw materials, nononaldehyde is prepared by carbonylation, and then nononic acid is obtained by air oxidation. During laboratory preparation, the resteamed diethyl malonate can be added to sodium butanol, heated to 80-90 ℃, and bromoheptane can be added to slowly reflux the reactants until litmus is neutral. Then add the potassium hydroxide solution, heat and reflux for 4-5h, after the saponification is completed, carry out steam distillation, and steam until there is no butanol distillation. Concentrated hydrochloric acid is added into the residual liquid, refluxed for 1h, then cooled and separated into oil layers and heated. When carbon dioxide release is stopped at 180 ℃, the oil in the reactant is crude nonanoic acid. Distillation under reduced pressure, 140-142 ℃(1.6kPa) fraction was collected to obtain finished nonanoic acid with a yield of about 70%. It is obtained by oxidation of nonanol or nonaldehyde or methyl nonone. Oleic acid is obtained by ozone oxidation. |
