What is Oleic Acid?

Oleic acid is an unsaturated fatty acid with a carbon-carbon dual bond in its molecular framework, and also it is a fat that makes up olein. One of one of the most widely present all-natural unsaturated fats. Oleic acid can be gotten by hydrolysis of oil, and its chemical formula is CH3(CH2)7CH=CH(CH2)7 · COOH. Glycerides of oleic acid are just one of the major elements of olive oil, palm oil, lard and also other animal and also vegetable fats. Industrial items usually have 7-12% saturated fatty acids (palmitic acid, stearic acid) and a small amount of other unsaturated fatty acids (linoleic acid). Anemic oily liquid. The particular gravity is 0.895 (25/25 ° C). The freezing point is 4 ° C. The boiling point is 286 ° C(13,332 ). The refractive index is 1.463 (18 ° C). The iodine value is 89.9 and also the acid worth is 198.6. Insoluble in water, soluble in alcohol, benzene, chloroform, ether as well as other unpredictable or non-volatile oils. When subjected to the air, specifically when it has some contaminations, it is quickly oxidized, the color turns yellow or brownish, and also it has a rancid odor. It disintegrates when heated up to 80-100 ° C under normal stress. It is acquired by saponification and acidification of pet and vegetable oils. Oleic acid is a vital nutrient in animal food. Its lead salts, manganese salts, as well as cobalt salts are paint drier; copper salts are fishing net preservatives; light weight aluminum salts can be utilized as textile waterproofing representatives as well as thickeners for certain lubricating oils. Oleic acid can be epoxidized to produce epoxy oleate (plasticizer). Azelaic acid (basic material of polyamide resin) is created by oxidative fracturing. Airtight, dark storage.
Oleic acid is mostly existing in pet and veggie oils in huge quantities in the form of glycerides. Certain simple oleic acid esters are used in the fabric, leather, cosmetic and pharmaceutical markets. The alkali steel salt of oleic acid is soluble in water as well as is one of the cornerstones of soap. The lead, copper, calcium, mercury, zinc as well as other salts of oleic acid are insoluble in water and also can be used as dry lubricating substances, repaint desiccants and waterproofing representatives.
Oleic acid is generally stemmed from nature, as well as oleic acid can be obtained by saponification as well as acidification of oil with high oleic acid web content. Oleic acid has cis as well as trans isomers, and also natural oleic acid has a cis framework (the trans framework can not be soaked up by the body). It has a particular impact on softening blood vessels and also plays an important role in the metabolic procedure of people and animals, but the body itself Artificial oleic acid can not satisfy the requirements as well as must be consumed from food, so eating oil with higher oleic acid material benefits health and wellness.

Oleic Acid Uses

1. Oleic Acid is mainly used to prepare plastic plasticizer epoxy butyl oleate and also epoxy octyl oleate. It is used in the prep work of antistatic representative and lubricating conditioner in wool spinning sector. In the timber market, it is utilized to prepare paraffin solution of anti-water agent. Azelaic acid can be prepared by oxidation, as well as azelaic acid is the raw product for preparing polyamide material. It can likewise be utilized in the manufacture of chemical emulsifiers, printing and also dyeing accessories, industrial solvents, mineral flotation representatives as well as launch representatives, and so on. It can additionally be used to prepare carbon paper, inputting paper, ballpoint pen oil as well as different oleates, and so on

2. Oleic Acid can be utilized as a lubricating and also unblocking representative for piercing mud. The salt or potassium salt of oleic acid is just one of the ingredients of soap. Pure salt oleate has great detergency, can be utilized as surfactants such as emulsifiers, and also can be made use of to deal with cholelithiasis. Other steel salts of oleic acid can likewise be made use of in waterproof materials, lubricants, polishing agents, etc, and its barium salt can be made use of as a rodenticide.

3. Oleic Acid is utilized for biochemical evaluation and also gas chromatography reference material.

4. Used in the prep work of plastic plasticizers, pesticide emulsifiers, lubricating substances, lotions, ore flotation agents, and so on

5. Oleic Acid is made use of as a basic material for detergents, fat soap bases, cosmetics, chemical fiber oils, and also textile accessories. Refined oleic acid is used as a raw material for plastics, design plastics, nylon 8 and nylon 9.

6. Used in baked food, meat items and also spices.

Oleic Acid Production Process

1. Oleic acid, together with various other fats, exists in all pet and also veggie oils in the form of glyceride. In animal fat, oleic acid make up regarding 40-50% of fats. The web content in grease differs considerably, it can be as high as 83% in tea oil, 54% in peanut oil, and just 5-6% in coconut oil. Oleic acid is a co-product of stearic acid production, and also both commercial stearic acid and also industrial oleic acid actually contain various other fatty acids. There are lots of oil resources for the manufacturing of stearic acid and also oleic acid. In industry, a combined oil formula is generally made use of, such as 30% melted tallow, 10% melted lard, 40% bone fat and 20% cottonseed oil. Among the blended fats gotten by refining and also hydrolyzing oils and fats, the melting points of saturated acids and also unsaturated acids are quite various. The return of stearic acid as well as oleic acid primarily depends on the formula of oil and also ester. Usually, 30-50% oleic acid and also 50-70% stearic acid can be obtained by chilly pushing. Hydrolyze with pet and also veggie oils and also emulsions at 105 ° C, cleanse with stearic acid, eliminate stearic acid by pushing when, different crude oleic acid, dehydrate, distill and also ice up. It is pushed once again to get rid of palmitic acid, and also finally dehydrated as well as fine-tuned to obtain the completed item. This technique can co-produce stearic acid, as well as likewise co-produce oleic acid when stearic acid is produced from oleic acid. Basic material consumption allocation: pet and grease 1950kg/t, sulfuric acid (98%) 210kg/t.

2. Use fats and also oils containing a particular amount of oleic acid as raw materials, such as tallow, lard, and hand oil, to decay fats, liquify and also cool down the fats with a solvent, and remove solid fatty acids to obtain crude oleic acid. Then dissolve it with a solvent, and cool it at a reduced temperature level to take shape the oleic acid.

Refining technique: Recrystallize with acetone at -10 ~ -60 ° C to different oleic acid from linoleic acid and saturated fatty acids. Recurring saturated fatty acids can be sped up by producing lead salts in ethanol, and after that refined by purification. Usually, commercially offered oleic acid can be taken shape with acetone at -11 ° C, as well as the crystals can be ground and also dried out in vacuum for one week. Various other refining approaches include: converting oleic acid right into methyl oleate, hydrolyzing the ester after fractional purification, and recrystallizing the complimentary acid with acetone at -40 ~ -45 ° C. Use 12 mL of acetone per 1 g of oleic acid. There is also a technique of fractional crystallization of the melt of oleic acid, adhered to by molecular purification as well as purification at a stress of 133.3 MPa.

3. Take oil and hydrolyze to acquire blended fatty acids, and also the fluid component gotten by chilly pressing is oleic acid, and also the saturated fatty acids in the solid component are eliminated. Acetone can be utilized as a solvent to acquire pure item.

4. Take on stearic acid co-production approach. When manufacturing stearic acid, the pressed unsaturated fat is additional icy as well as pushed to separate saturated fatty acid and then dried out. Or it can be gotten by saponifying, acidifying, separating and distilling soapstock when preparing grease.

The Preparation Method of Oleic Acid

1) Extract oleic acid directly from grease, that is, extract by saponification, strike steam right into the oil under mixing, raise the temperature to 80-100 ° C, and afterwards include lye to hydrolyze the oil. Combined fatty acids are obtained after hydrolysis, as well as they are divided by distillation and also air conditioning. This approach is labor-intensive, eats a lot of energy as well as antacids, and also is typically not made use of.
( 2) Utilizing vegetable oil or animal oil as resources, oleic acid is prepared by air pressure catalytic hydrolysis, and the catalyst can be alkylbenzenesulfonic acid. The periodic medium-pressure catalytic fracturing method can also be used, the driver can be zinc oxide, the stress is 10.13 × 105 ~ 35.46 × 105Pa, and also the temperature is 150 ~ 230 ° C. Continual, countercurrent, and high-pressure fracturing techniques can additionally be used. The stress is 5-5.2 MPa, the temperature level is 260 ° C, and the stimulant can be zinc oxide. This technique has higher advantages than the previous 2 approaches, but it is not appropriate for oils with high unsaturation and also hydroxyl groups. Using the above 3 techniques, mixed fatty acids can be prepared, and after that divided as well as fine-tuned. First, utilize purification to execute harsh splitting up, and the distillation is performed under lowered pressure (0.133 × 103 ~ 1.07 × 103Pa). Maintain the distillation temperature not going beyond 260 ° C. The distilled fatty acids are further rectified using their boiling point distinction. According to the different melting points of numerous fatty acids, it can be refined by condensation. It can also be improved by solvent removal.
( 3) Synthetic oleic acid. In 1925, oleic acid was manufactured from ethyl acetoacetate. With the development of the petrochemical sector, the process of manufacturing oleic acid has additionally been developed, as well as oleic acid can be prepared from oil olefins.
