What is Pure Oleic Acid?

Pure Oleic Acid is an unsaturated fat with a carbon-carbon dual bond in its molecular framework, which is the fatty acid that composes olein. Amongst one of the most prevalent kinds of normally occurring unsaturated fatty acids. Pure Oleic Acid can be gotten by oil hydrolysis, and additionally its chemical formula is CH3(CH2)7CH=CH(CH2)7 · COOH. Glycerides of oleic acid are among the main aspects of olive oil, hand oil, lard and numerous other pet dog as well as also vegetable oils. Business products often consist of 7-12% saturated fatty acids (palmitic acid, stearic acid) in addition to a percentage of various other unsaturated fats (linoleic acid). Anemic oily fluid. Specific gravity 0.895 (25/25 ° C). Freezing point 4 ℃. The boiling point of 286 ° C (13,332 ). Refractive index 1.463 (18 ° C). The iodine well worth is 89.9 as well as the acid well worth is 198.6. Insoluble in water, soluble in alcohol, benzene, chloroform, ether as well as likewise other uncertain or set oils. When exposed to the air, specifically when it includes some contaminations, it is conveniently oxidized, the shade turns yellow or brown, as well as it has a rancid smell. It breaks down when warmed to 80-100 ° C under normal tension. It is obtained by saponification as well as acidification of animal and also veggie oils. Oleic acid is an important nutrient in animal food. Its lead, manganese and cobalt salts are paint driers; copper salts are preservatives for angling nets; light weight light weight aluminum salts can be made use of as textile water repellents and also thickeners without a doubt lubricating oils. Oleic acid is epoxidized to develop epoxidized oleate (plasticizer). Oxidative cracking to generate azelaic acid (resources of polyamide product). Airtight, dark storage space.
Pure Oleic Acid is mostly existing in pet along with vegetable oils as well as fats in the form of glycerides. Some very easy oleates are utilized in the material, natural leather, cosmetic and additionally pharmaceutical markets. The alkali steel salt of oleic acid liquifies in water and is simply one of the primary parts of soap. Lead, copper, calcium, mercury, zinc as well as numerous other salts of oleic acid are insoluble in water as well as can be made use of as completely dry lubricating substances, paint driers along with water repellents.
Pure Oleic Acid is mostly originated from nature, in addition to oleic acid can be obtained by saponification, acidification and also splitting up of oils as well as fats with high oleic acid web content. Oleic acid has cis-trans isomers, as well as all-natural oleic acid is a cis-structure (trans-structure can not be soaked up by the body), which has a particular effect on softening blood vessels, along with similarly plays an essential duty in the metabolic rate of individuals as well as likewise animals, however the body itself Synthetic oleic acid can not meet the demands as well as need to be ingested from food, so it benefits health and wellness to take in cooking oil with a high content of oleic acid.

Activates healthy protein kinases in hepatocytes. A 75% alcohol remedy of Pure Oleic Acid can be made use of as a corrosion cleaner.

Production Process of Pure Oleic Acid

1. Pure Oleic Acid, along with other fats, exists in all animal as well as vegetable oils in the form of glycerides. In animal fats, oleic acid represent regarding 40-50% of fatty acids. The content of vegetable oil differs considerably, as high as 83% in tea oil, 54% in peanut oil, as well as just 5-6% in coconut oil. Oleic acid is a co-product in the production of stearic acid, and both industrial stearic acid as well as industrial oleic acid in fact include other fatty acids. There are several oil as well as fat resources made use of for the manufacturing of stearic acid and Pure Oleic Acid. In industry, combined oil formulas are normally utilized, such as 30% thawed tallow, 10% melted lard, 40% bone fat and also 20% cottonseed oil. Amongst the mixed fatty acids gotten by refining and also hydrolysis of oils and also fats, the melting point of saturated acid as well as unsaturated acid is fairly various. The returns of stearic acid and oleic acid are generally determined by the solution of oil esters. As a whole, cold pushing can obtain 30-50% oleic acid and 50-70% stearic acid. The animal as well as grease and solution are hydrolyzed at 105 ° C, detoxified with stearic acid, and the stearic acid is eliminated by pushing once to get crude oleic acid, which is dried out, distilled and iced up. After additional pushing, palmitic acid is eliminated, and also finally the finished item is obtained by dehydration and refining. This technique can co-produce stearic acid. In a similar way, when stearic acid is generated from oleic acid, oleic acid will likewise be co-produced. Resources consumption quota: pet as well as grease 1950kg/t, sulfuric acid (98%) 210kg/t.

2. Use oils and also fats containing a certain quantity of Pure Oleic Acid as basic materials, such as tallow, lard, and also hand oil, to decay fats, dissolve and cool the fats with a solvent, and eliminate strong fats to obtain crude oleic acid. Liquify with solvent as well as cool at low temperature level to crystallize Pure Oleic Acid.

Refining technique: recrystallize with acetone at -10 ~ -60 ℃, and oleic acid can be separated from linoleic acid and saturated fatty acid. Recurring saturated fatty acids can be sped up by the development of lead salts in ethanol, and afterwards purified by purification. Normally, readily offered oleic acid can be crystallized with acetone at -11 ° C, and also the crystals can be squashed as well as dried out in vacuum for one week. Other refining approaches consist of: converting oleic acid right into methyl oleate, hydrolyzing the ester after fractionation, and also recrystallizing the complimentary acid with acetone at -40 ~ -45 ° C. Use 12 mL of acetone per 1 g of oleic acid. There is likewise a method of fractional crystallization of the melt of oleic acid, followed by molecular distillation filtration at a stress of 133.3 MPa.

3. Take oil and hydrolyze to obtain blended fat, and also the liquid part acquired by cold pressing is Pure Oleic Acid, and the solid part of saturated fatty acid is removed. Acetone can be used as solvent to acquire pure product.

4. Making use of stearic acid co-production method. In the synthesis of stearic acid, the pressed unsaturated fats are additional frozen as well as pushed, the saturated fatty acids are separated, and afterwards dried out. Or in the prep work of grease, the soapstock is gotten by saponification, acidification, separation and distillation.

Preparation Method of Pure Oleic Acid

(1) Extract Pure Oleic Acid directly from vegetable oil, that is, extract by saponification method, blow steam into the oil under stirring, raise the temperature to 80-100 ℃, and then add lye to hydrolyze the oil. After hydrolysis, mixed fatty acids are obtained, and these are separated by distillation and cooling. This method is labor-intensive, energy consumption, and alkali consumption, and is generally not used.
(2) Using vegetable oil or animal oil as raw material, the Pure Oleic Acid is prepared by normal pressure catalytic hydrolysis method, and the catalyst can be alkylbenzene sulfonic acid. The intermittent medium-pressure catalytic cracking method can also be used, and the catalyst can be selected from zinc oxide, the pressure is 10.13×105～35.46×105Pa, and the temperature is 150～230℃. Continuous, countercurrent, high pressure cracking method can also be used, the pressure is 5-5.2MPa, the temperature is 260℃, and zinc oxide can be used as the catalyst. This method has higher benefits than the previous two, but it is not suitable for oils with high unsaturation and hydroxyl groups. . Using the above three methods, mixed fatty acids can be prepared, and then separated and refined. First, a crude fraction was carried out by distillation, and the distillation was carried out under reduced pressure (0.133×10 3 to 1.07×10 3 Pa). The distillation temperature was maintained not to exceed 260°C. The distilled fatty acids are further rectified using their boiling point difference. Depending on the melting point of various fatty acids, it can be purified by a crystallization method. It can also be purified by solvent extraction.
(3) Artificial synthesis of Pure Oleic Acid. In 1925, oleic acid was synthesized from ethyl acetoacetate. With the development of the petrochemical industry, the synthesis of Pure Oleic Acid has also been developed, and Pure Oleic Acid can be prepared from petroleum olefins.
