Background and Overview
Odd chain fatty acids (OCFA), including 21-carbonic acid, function similarly to unsaturated fatty acids and help improve the fluidity of cell membranes. The content in some bacteria is high, but the content in animals and lower plants does not exceed 1%. Odd-carbon fatty acids produce sugar residues after metabolism, so they have better nutritional effects and no adverse effects; in addition, triglycerides containing odd-carbon fatty acids can reduce the occurrence of secondary complications in sepsis and intensive care treatment. The frequency may reduce inflammation or shorten the course of disease. The increase in odd-carbon fatty acids is also considered to be an adaptive mechanism for microorganisms to cope with environmental stress. Since odd-numbered fatty acids are synthesized in very small amounts in nature, they are often added as internal references for quantitative analysis of fatty acids and fatty acid intake analysis.
Main applications of henoconic acid
Heconic acid can be used as an anionic surfactant, such as preparing surfactant cleaning fracturing fluid, including the following steps: 1) reacting the anionic surfactant with a strong base to obtain product A; 2) the product A The surfactant cleaning fracturing fluid is obtained by reacting with the cationic surfactant. In the above preparation method, the anionic surfactant can be a long-chain saturated or unsaturated fatty acid, specifically, it can be behenic acid, behenic acid, behenic acid or behenic acid, etc.
Heconic acid can also be used to prepare a sweating and rubber protective wax. On the basis of the ordinary sweating process, oil-soluble emulsifiers and oil-soluble acids are dissolved in the sweating raw materials as the oil phase material, and the inorganic salt solution is used as the water phase material. After emulsification, sweating is carried out, and the oil-soluble acid and the inorganic salt are reacted to generate After the bubbles and salt solution are discharged, a small space is formed, forming a channel for oil discharge to facilitate the rapid discharge of oil. At the same time, the air flow is used to pass through the wax layer during the sweating process to forcefully separate the wax and oil, thereby quickly and effectively removing the rubber protection in the paraffin. Unsuitable components of wax are then formulated to produce rubber protective wax products. Described oil-soluble acid is selected from n-unitary acid, n-decanoic acid, n-undecanoic acid, lauric acid, n-tridecanoic acid, myristic acid, n-pentadecaic acid, palmitic acid, pearlescent acid, stearic acid, n- Nadecaic acid, arachidic acid, n-27-acid, behenic acid, n-23-acid, lignoceric acid, n-25-acid, ceric acid, n-27-acid, montanic acid, n-29-acid A group of substances composed of , melicic acid, n-triacontanic acid, lactic acid, phyllic acid, linoleic acid, palmitoleic acid, oleic acid, erucic acid, and selachyl acid. It is preferably an organic acid that has no special odor, is non-toxic, is easily available and low-priced, and has a melting point lower than the maximum temperature for sweating and heating in step (B3). It is selected from linoleic acid, palmitoleic acid, oleic acid, erucic acid, and sharkleic acid. , a group of substances composed of n-decanoic acid, n-undecanoic acid, lauric acid and n-tridecanoic acid.
