What are the main uses of stearic acid?
Stearic acid, whose name comes from the Spanish Stearic Acid, is a common fatty acid. It has a wide range of uses and has important applications in various fields.
In industrial manufacturing, stearic acid is often an indispensable raw material. In the plastics industry, it can be used as a lubricant and a mold release agent. The power of these two is to make the surface of plastic products smoother and easier to come out of the mold, ensuring a smooth production process. For example, when producing plastic pipes and plastic films, adding stearic acid can improve the processing performance of plastics and improve the quality of products.
In the rubber industry, stearic acid also plays a key role. As a vulcanizing active agent, it can improve the reaction efficiency between rubber and vulcanizing agent, making the vulcanization process of rubber more rapid and sufficient. In this way, the physical properties of rubber products, such as strength, elasticity and wear resistance, can be significantly improved. Like tire manufacturing, stearic acid is an important auxiliary to improve rubber properties.
In the cosmetic industry, the application of stearic acid is also quite common. Because of its good emulsifying properties, it is often used in the manufacture of various skin care products and cosmetics, such as creams, lotions, lipsticks, etc. Stearic acid can evenly mix the oil phase and the water phase to form a stable emulsion, making the cosmetic texture more delicate, smoother to apply, and helping to extend the shelf life of the product.
In the field of candle manufacturing, stearic acid can improve the hardness and finish of candles. After stearic acid is added, the candle burns more stably, and it is not easy to deform and wax, thereby improving the experience and quality of candles.
In addition, stearic acid also has a place in the field of food additives. It can be used as a food lubricant and mold release agent to ensure smooth demoulding of food during food processing, and to avoid food sticking to processing equipment without affecting the flavor and safety of food.
What are the physical properties of Stearic Acid?
Stearic acid has a white and greasy appearance, is usually solid, and is stable at room temperature. Its melting point is about 70 degrees to 2 degrees. When heated, it melts into a liquid, and cools and solidifies. This substance is odorless or slightly fragrant, and it feels greasy to the touch.
The density of stearic acid is about 0.91 grams per cubic centimeter, which is lighter than water, so it can float on the water surface. Its solubility is also special. It is insoluble in water, but it can be soluble in hot alcohols, ethers, chloroform and other organic solvents. In alcohol, it is easy to dissolve when hot, and gradually dissolves when cold.
Stearic acid has good stability and is not easy to deteriorate at room temperature and pressure. In case of strong oxidants, it can also react. In the air, if it is exposed for a long time or heated too much, it may also be gradually oxidized.
In addition, stearic acid has certain lubricity and is often used as a lubricant and a mold release agent in industry. Because it can reduce the friction between objects and objects, make the surface of the product smooth and easy to shape. And because of its stable chemical properties, it is also used for the modification of many materials to increase their performance.
In which industries is stearic acid widely used?
Stearic acid, a common saturated fatty acid, is widely used in many industries.
In the daily chemical industry, it has a wide range of uses. In the field of soap making, stearic acid and alkali undergo a saponification reaction and can be made into soap. This soap has strong decontamination ability and is mild in nature, making it common in daily cleaning products. In the cosmetic industry, stearic acid can be used as an emulsifier to evenly mix the oil phase and the water phase. Products such as creams and lotions, because of stearic acid, the texture is more delicate, stable, and the application is more uniform.
Stearic acid is also commonly used in the plastics industry. It can act as a lubricant, reduce the melt viscosity of plastics during processing, improve its fluidity, make plastic products form more smoothly, and prevent plastics from sticking to the surface of equipment during processing, improving production efficiency. At the same time, stearic acid can also enhance the release performance of plastics, making plastic products easier to come out of the mold and reducing the rate of defective products.
In the rubber industry, stearic acid is also indispensable. It can be used as a vulcanization active agent to increase the vulcanization speed and crosslinking degree of rubber, thereby enhancing the physical properties of rubber products, such as hardness and tensile strength. In addition, stearic acid can also improve the compatibility between rubber and filler, so that the filler is more evenly dispersed in the rubber, and improve the quality of rubber products.
Stearic acid is also used in the food industry. It is often used as a food additive, mainly as a release agent and anti-stick agent. In the production of baked goods, a preparation containing stearic acid is applied on the surface of the mold to prevent food such as bread and cakes from sticking to the mold, which is convenient for release. Stearic acid is safe and meets the relevant standards for food additives.
What are the production methods of stearic acid (Stearic Acid)?
For stearic acid, there are three methods.
One is the method of separation. Take vegetable oils, such as tallow and palm oil, and separate them by steam. The boiling of different fatty acids is high, and the boiling of stearic acid is high. In the process of separation, other components can be obtained. This is an ancient method, but it is easy to operate and easy to produce.
The second method is the hydrolysis method. Vegetable oils are boiled in water, or added with acid or catalysis, to hydrolyze the oil. For oils, triglycerides are also hydrolyzed to produce fatty acids and glycerol. If catalysis is used, fatty acids are obtained, which are treated with acids, and fatty acids are synthesized. Stearic acid is among them. With sulfuric acid as catalyst, the reaction rate is fast and the yield is high; with sulfuric acid as catalyst, the reaction rate is high, and the product quality is good.
The third is the synthesis method. With petrochemical raw materials, such as ethylene, carbon monoxide, etc. First, carbonyl is synthesized to obtain high-quality fatty acids, and then it is divided and refined to obtain stearic acid. This way, the raw materials are rich, and they are not limited by natural sources. However, high-tech technology is required, and many large-scale molds are used for production.
What are the precautions during the use of stearic acid (Stearic Acid)?
When using stearic acid, all kinds of matters must not be ignored.
First, it is related to storage. Stearic acid prefers dry and cool places, and should be protected from direct sunlight and away from fire and heat sources. If it is in a humid and hot place, or close to fire and heat, it may cause its properties to change, which is not good for subsequent use.
Second, it is about operation. When handling, be careful. Or wear protective clothing, protective gloves and goggles to prevent stearic acid from touching the skin and eyes. Although it is not highly toxic, it may come into contact with the body and cause discomfort.
Third, it is related to compatibility. When using stearic acid, it is necessary to carefully check the complexes with it. Do not co-locate or mix with strong oxidizing agents and other substances. Otherwise, it may cause a biochemical reaction and cause a dangerous situation.
Fourth, about weighing. When using stearic acid, the weighing must be accurate. Large amounts and small amounts can affect the final effect. More may cause excessive reactions, and less than expected efficacy.
Fifth, apply to industrial production scenarios. In the process, temperature, time and other conditions also need to be strictly controlled. Improper temperature, or the melting of stearic acid, abnormal reaction state; wrong time, it is difficult to achieve the desired effect.
For those who use stearic acid, the above things should be kept in mind and used with caution to ensure its safety and effectiveness.
