English title : n - Nonanoic acid; Nonanoic acid; Pelargonic acid; 1-octanecarboxylic acid; acide nonylique normal; acide pelargonique
traits Description : colorless or pale yellow oily liquid. Industrial products are pale yellow. A special micro-odor. 11-12.5 ° C melting point, boiling point, 255.6 ° C and relative density (20 / 4 ° C) 0.904-0.910, refractive index (nD20) 1.4322. Soluble alcohol, chloroform and ether organic solvents, do not dissolve in water.
production methods : the goods natural materials (free or esterification state) exist in roses, geraniol, Iris, hops, such as lavender essential oil. Industrial by 1-octene derived or oleic acid oxidation.
1. Nitric acid or oleic acid by ozone oxidation.
2. 1-octene and synthetic gas as raw material, by carbonylation system in the previous aldehyde, then by air to be Azelaic acid oxidation. Preparation Laboratory and can be re-steamed off to join DIETHYL butanol sodium, heated to 80-90 ° C, by adding bromine heptane, the reaction from litmus slowly back to neutral. Before adding potassium hydroxide solution, heating returning 4-5h, saponification completed after steam distillation, steaming to be no alcohol distillation. To join concentrated hydrochloric acid residue, returning after 1h separation cooling reservoir heating to 180 ° C when cease to emit carbon dioxide, the reaction from the bar that crude oil goods Azelaic Acid. Vacuum distillation, collecting 140-142 ° C (1.6kPa) distillate, in finished Azelaic acid, the yield of about 70%.
purposes : synthetic organic materials, by oxidation system Azelaic Acid, ammoniated hydride system may sic amine, can be used to pressure hydrogenation sic alcohol. Azelaic acid is also used in the production of Azelaic Acid Ester plasticizers, also used paint desiccant. Azelaic Acid pale fat and coconut aroma, my GB2760-86 provides for the use of food flavors, mainly used for preparation of coconut flavor and berries.
