What are the physical and chemical properties of 12-Hydroxystearyl Alcohol
12-Hydroxystearyl alcohol, its physical and chemical properties are quite unique. At room temperature, this substance is mostly in a solid state, with a relatively solid texture, just like uncut jade. Looking at its appearance, it is often a white to slightly yellow waxy solid, just like the first snow in winter covering the branches, pure and elegant color.
When it comes to solubility, 12-hydroxystearyl alcohol has a good solubility in organic solvents, such as oils and alcohols. It is like a fish entering water and blends freely. However, in water, its solubility is very small, just like oil droplets entering water, which is difficult to miscible. This characteristic makes it used in many industrial fields to cooperate with different solvents and display its own capabilities.
Its melting point is within a specific range, just like cooking with precise heat, and its shape can be changed at a suitable temperature. Generally speaking, the melting point makes it stable at room temperature, and it can be softened and melted when heated, so that it is easy to process and shape, and can be widely used in the manufacture of various products that require specific forms.
The chemical stability of 12-hydroxystearyl alcohol is also worth mentioning. Under normal circumstances, it is like a humble gentleman, relatively stable, and not easy to react violently with many substances. However, in case of extreme chemical environments such as strong acids and alkalis, its structure may be affected and corresponding chemical changes will occur. This is just like a gentleman also has its perseverance. In case of excessive external force, it is difficult to maintain its own state.
In terms of surface activity, although it is not as strong as professional surfactants, it also has certain performance. It can reduce the surface tension of the liquid to a certain extent, just like the ripples on the surface of a calm lake, which has a subtle impact on the properties of the interface. In some situations where the interface performance needs to be regulated, it can play an auxiliary role.
12-Hydroxystearyl Alcohol is widely used in which industries
12-Hydroxystearyl alcohol is widely used in various industries. In the daily chemical industry, its application is particularly significant. Because of its good emulsifying, thickening and emollient effects, it is often used in skin care products. Such as creams, lotions, etc., can make the texture of the product more delicate, smoother when applied, and can form a protective film on the surface of the skin, effectively locking in skin moisture, achieving moisturizing effect, and keeping the skin hydrated and smooth for a long time.
In the paint industry, 12-hydroxystearyl alcohol is also indispensable. It can be used as a rheological aid to effectively adjust the viscosity and leveling of coatings. When the paint is applied, it can avoid the occurrence of hanging phenomenon, so that the paint can be evenly covered on the surface of the object, thereby improving the quality and aesthetics of the coating.
Furthermore, in the plastics industry, it also plays an important role. Often used as a lubricant, it can reduce the friction between the components in the plastic processing process, make the plastic molding smoother, reduce the surface defects of plastic products, and improve the quality and appearance of plastic products.
In addition, in the ink industry, 12-hydroxystearyl alcohol can improve the fluidity and drying performance of the ink. When printing, it can transfer the ink evenly to the printing material, ensure that the printing pattern is clear and bright, and can accelerate the drying of the ink, prevent the phenomenon of rubbing, and improve the printing efficiency and quality.
In short, 12-hydroxystearyl alcohol is widely used in many industries such as daily chemicals, coatings, plastics, inks, etc., and is of critical significance to product performance improvement and quality assurance in various industries.
What should be paid attention to when using 12-Hydroxystearyl Alcohol
12-Hydroxystearyl alcohol is an important chemical substance. When using it, many matters need to be paid attention to.
The first priority is safety protection. This substance may pose a certain hazard to the human body, and may cause discomfort if it touches the skin, eyes, or is inhaled or ingested. When operating, be sure to wear appropriate protective equipment, such as gloves, goggles, and protective clothing to prevent direct contact with the body. If it is accidentally touched, it should be rinsed with plenty of water immediately. If the situation is serious, seek medical attention in time.
This is the storage condition. 12-Hydroxystearyl alcohol should be stored in a cool, dry and well-ventilated place, away from fire and heat sources. Because it is flammable, improper storage can easily cause fire hazards. At the same time, it is necessary to avoid mixing with strong oxidants, acids and other substances to prevent chemical reactions from occurring, resulting in deterioration or danger.
The other is the specification for use. Before use, it is necessary to fully understand its physical and chemical properties and scope of application, and precisely control the dosage according to specific needs and processes. Do not use excessive amounts at will, so as not to affect product quality or cause other adverse consequences. And during use, strictly follow the established operating procedures to ensure the safety of the operating environment.
In addition, after use, the remaining substances and containers should also be properly disposed of. The remaining 12-hydroxystearyl alcohol cannot be discarded at will, and should be recycled or disposed of according to regulations. The container should be cleaned. If the container is damaged or contaminated, it should be handled in accordance with relevant regulations to prevent pollution to the environment.
What is the production process of 12-Hydroxystearyl Alcohol?
The production process of 12-hydroxystearyl alcohol is very delicate. In the past, to make this product, first take natural oils, such as castor oil, which is the starting material.
Saponification of castor oil, blending with lye, at a suitable temperature and duration, hydrolysis of oil, raw sodium ricinoleate and glycerin. In this case, the temperature needs to be carefully controlled. If it is too high, the product will be damaged, and if it is too low, the reaction will be slow.
After saponification is completed, the method of acidification is followed. Neutralize the saponification product with acid solution, so that sodium ricinoleate is converted into ricinoleic acid. The concentration and dosage of acid are fixed, and it is necessary to accurately grasp before pure ricinoleic acid can be obtained.
Then, the ricinoleic acid is hydrogenated. When the catalyst exists, hydrogen is introduced to hydrosaturate the unsaturated bond of ricinoleic acid, and finally 12-hydroxystearic acid is obtained. In this step, the choice of catalyst, hydrogen pressure and reaction temperature are all key, which affect the quality and yield of the product.
Then 12-hydroxystearic acid is reduced by a specific reducing agent, under appropriate conditions, the carboxyl group is reduced to a hydroxyl group, and then 12-hydroxystearyl alcohol is obtained. The reduction process requires strict requirements on the reaction environment, and there is no water and no oxygen to ensure a smooth reaction and pure product.
This production process is interlocked step by step, and each link requires fine operation. If there is a slight difference, it is difficult to obtain high-quality 12-hydroxystearyl alcohol.
