Preparation of Suberic acid:
Suberic acid is normally made from castor oil, which is essentially glycerol triricinoleate.
The castor oil is heated with sodium hydroxide at about 250°e.

This treatment results in saponification of the castor oil to ricinoleic acid which is then cleaved to give 2-octanol and Suberic acid:
This process results in low yields of Suberic acid (about 50% based on the castor oil) but, nevertheless, other routes have not proved competitive.
Suberic acid is a colourless crystalline solid, m.p. 134℃.

The Main Method of Preparation:
(1) Castor oil is as raw material, ricinoleate is separated from castor oil, with the condition of inflating and 280~300℃, caustic soda proceeds alkali fusion and the reaction is heated for 10h, sebum acid sodium salt can obtain, deputy product is 2-octanol.
The sodium salt is dissolved in water, adding sulfuric acid to neutralize, after bleaching, the solution is cooled to precipitate sebum acid, Suberic acid is washed with cold water, and finally recrystallized.

CH3 (CH2) 5CH (OH) CH2CH = CH (CH2) 7COOH +
2NaOH → CH3 (CH2) 5CH (OH) CH3 + NaOOC (CH2) 8COONa + H2
NaOOC (CH2) 3COONa + H2SO4 → HOOC (CH2) 8COOH + Na2SO4

(2) Adipic acid (hexane diacid) is as raw material to synthesize.
Adipic acid and methanol can proceed esterification reaction to form dimethyl adipate, ion exchange membrane proceeds electrolytic oxidation to get dimer, i.e., dimethyl sebacate, and then reacts with sodium hydroxide to form the disodium salt, hydrochloric acid (or sulfuric acid) is used to neutralize and Suberic acid can obtain.

Production of Suberic acid:
Suberic acid is produced from castor oil by cleavage of ricinoleic acid, which is obtained from castor oil.
Octanol & glycerin is a byproduct.
Suberic acid can also be obtained from decalin via the tertiary hydroperoxide, which gives cyclodecenone, a precursor to Suberic acid.

Octanol & glycerin is a byproduct.

Suberic acid can also be obtained from decalin via the tertiary hydroperoxide, which gives cyclodecenone, a precursor to Suberic acid.
Almost all of the current industrial production of Suberic acid is using castor oil as raw material.

Castor oil cracking method:
Castor oil is heated under the action of alkali hydrolysis to generate ricinoleic acid sodium soap, and then add sulfuric acid to generate ricinoleic acid; in the presence of diluent cresol, add alkali heated to 260-280 ℃ for cracking to generate Suberic acid double sodium salt and secoctanol and hydrogen, cracked material diluted by water, heated and neutralized with acid, the double sodium salt into a monosodium salt; and then boiled with acid after decolorization of activated carbon neutralization solution.
The monosodium salt of Suberic acid is turned into Suberic acid crystals, and then separated and dried to obtain the finished product.

Potential Medical Significance of Suberic acid:
Sebum is a secretion by skin sebaceous glands.
Suberic acid is a waxy set of lipids composed of triglycerides (≈41%), wax esters (≈26%), squalene (≈12%), and free fatty acids (≈16%).

Included in the free fatty acid secretions in sebum are polyunsaturated fatty acids and Suberic acid.
Suberic acid is also found in other lipids that coat the skin surface.
Human neutrophils can convert Suberic acid to its 5-oxo analog, i.e., 5-oxo-6E,8Z-octadecenoic acid, a structural analog of 5-oxo-eicosatetraenoic acid and like this oxo-eicosatetraenoic acid is an exceptionally potent activator of eosinophils, monocytes, and other pro-inflammatory cells from humans and other species.

This action is mediated by the OXER1 receptor on these cells.
Suberic acid is suggested that Suberic acid is converted to its 5-oxo analog during, and thereby stimulates pro-inflammatory cells to contribute to the worsening of, various inflammatory skin conditions.

Purification Methods of Suberic acid:
Purify Suberic acid via the disodium salt which, after crystallisation from boiling water (charcoal), is again converted to the free acid.
The free acid is crystallised repeatedly from hot distilled water or from Me2CO/pet ether and dried under vacuum.

Suberic acid is an alpha,omega-dicarboxylic acid that is the 1,8-dicarboxy derivative of octane.
Suberic acid has a role as a human metabolite and a plant metabolite.

Suberic acid is an alpha,omega-dicarboxylic acid and a dicarboxylic fatty acid.
Suberic acid is a conjugate acid of a sebacate(2-) and a sebacate.

Suberic acid derives from a hydride of a decane.

Stability and Reactivity of Suberic acid:

Reactivity:
Suberic acid reacts exothermically to neutralize bases, both organic and inorganic.
