What is Lauric acid?

Lauric acid is a major component of soap. Typical amphiphiles, head and tail ends of different affinity. The head is polar molecule genes, hydrophilic. Tail is hydrocarbon chain lipophilic. When mixing water and oil soap when amphiphilic molecules assemble into layered automatically. Molecular end point oil head pointing to the water.
Low concentrations of soap, showing isotropic random distribution of amphiphilic molecules form micelles. Diluted with water micelles disappear. Wider extension will increase the concentration of micelle formation. Causes the formation of a series of liquid crystal phase. Cubic phase and hexagonal phase has emerged as the concentration increases.

Lauric acid - Preparation: industrial production methods can be grouped into two categories: First, from natural plant oils after saponification or decomposed under high temperature and pressure; second is separated from the synthesis of fatty acids. Japan, mainly in coconut oil and palm kernel oil as raw materials lauric acid. Lauric acid used for extracting natural vegetable oils are: coconut oil, Litsea kernel oil, palm kernel oil and mountain pepper benevolence oil. Other plants, such as palm kernel oil, rub tree oil, camphor oil and other preparation services also lauric acid. Extracting the remainder of C12 lauric acid fraction, containing a large dodecenoic acid, hydrogenated at atmospheric pressure, without catalyst, can be more than 86% conversion of hydrocarbon transfer is twelve acids.

Lauric acid - its purpose: dodecanoic acid surfactant most widely used in industry, in accordance with the classification of surface active agent, a cationic, anionic, nonionic and amphoteric. Lauric acid based surfactant species see the entry table. Lauric acid, lauryl alcohol derivative surfactants are also some disinfectant, such as sodium lauryl dimethyl benzyl ammonium chloride (benzalkonium chloride), dodecyl dimethyl benzyl ammonium bromide (benzalkonium bromide), dodecyl dimethyl (2 - phenoxyethyl) ammonium bromide (domiphen). Such derivatives lauryl dimethyl ammonium-2 ,4,5 - trichloro-phenol salts useful as citrus preservative. Lauric acid in plastic additives, food additives, spices, pharmaceutical industries have many applications.

Lauric acid can block HIV: U.S. scientists found that a commonly used in the food and cosmetics cheap compound that can help block the monkey monkey immunodeficiency virus (referred to SIV, that is, "the monkey version" of the AIDS virus) transmission. This discovery is expected to provide HIV prevention mankind new ways.
University of Minnesota research team recently published a new British "Nature" magazine reported that they were targeted to female monkeys for experiments found that lauric acid monoglyceride can effectively help prevent female monkeys infected with HIV.
Lauric acid monoglyceride are present in some plants the compound, it is often to extract this compound as a fungicide and preservative added to food, daily necessities, or cosmetics. "Nature" magazine, said there had also research team experimented with different fungicides inhibiting HIV infection, but the results were disappointing, and lauric acid monoglyceride have shown a significant inhibitory effect of HIV.

The performance of methyl palmitoleic acid ester

Methyl palmitoleic acid ester is ablaze chicken oil aqueous with the body 0.875 g / mL at 25 ° C (lit.). Its freezing point is 113 ° C and the baking point is 180 ° C.It is acclimated in auxiliary, oil artefact additives etc.This artefact should stored beneath 0 ° C. The best cost-effective Methyl palmitoleic acerbic ester, Master Germany co, ltd production, Welcome to buy Methyl palmitoleic acerbic ester, Methyl palmitoleic acerbic ester Is your best choice, Welcome To Contact Us. Acrylate, it is simple to ablaze and calefaction and the activity of the initiator, by bulk, band-aid or abeyance polymerized, but aswell with added monomers, to change the backdrop of the polymer. Furthermore, methyl acrylate and pentaerythritol, trimethylol propane and added reactions, polyfunctional crosslinking abettor can be acquired for the photosensitive coating, photosensitive ink. a-cyano acrylate, cyano able animosity and permeability, top courage of the adhering polymer, acclimated as metal, wood, glass, leather, adhesives. Achievement acrylate alkyl acrylate monomer by its capital amount of carbon atoms in the alkyl accumulation of. Acrylate-based rubber, oil resistance, calefaction attrition is better; the acrylic ester rubber-based, due to the access in the amount of carbon atoms in an alkyl group, an ester accumulation of the careful aftereffect of arctic groups increases, so that baptize was improved, and because the careful aftereffect of abrasion the intermolecular force of rubber, accretion the centralized plastic, so that the brittleness temperature is lowered, finer cold. If the two monomers and acclimated by the above, can be acquired amid the achievement of the elastic amid the two.

Methyl Methyl palmitoleic acid ester ancillary alternation to the solubility constant with a array of oil. Especially far mineral oil, which showed acceptable oil resistance, it is important appearance acrylic rubber. Room temperature, the oil attrition of essentially top acrylonitrile agreeable nitrile elastic agnate than chloroprene rubber, chlorosulfonated polyethylene, silicone rubber. However, in hot oil, and its achievement is far above to nitrile rubber, are apparent in Table 15-3. Acrylic elastic continued captivation in hot oil, due to ozone, oxygen is shielded, and appropriately achievement than added abiding in hot air. Such a abstraction can be established, at temperatures beneath 150 ℃ oil, acrylic rubber, fluorine elastic accepting a agnate oil resistance; oil at college temperatures, the additional fluorine rubber, in addition, attrition to beastly and vegetable oils, constructed lubricants , silicic acerbic ester hydraulic fluids with acceptable performance. Acrylate adherence is aswell reflected in a actual acceptable attrition to ozone, UV birthmark is aswell actual good, appearance a advanced range, acceptable for light-colored blanket material, in accession to accomplished weather, crumbling attrition Flexing and cut advance resistance, permeability, but the electrical achievement is poor. Since the solubility constant of a polyacrylate adhesive and the solubility constant of the uncured or less, there is a acceptable miscibility amid the two. Polyacrylate courage and because no bifold bonds, it has acceptable thermal oxidation. Aqueous elastic apathetic adhesive acrylate determinants are: the elastic appearance is formed, the agreement and adaptability of the elastic phase, the elastic appearance atom admeasurement administration of the elastic appearance and the cast adhesive and the adhesive adhesive cast chemically affirmed to the atomic anatomy and l in its atom absorption of adhesive anatomic groups.
