12-Hydroxystearic Acid Correlation Theory
12-Hydroxystearic Acid, with its unique properties, is widely used in various fields, and its preparation methods are also different.
1. Properties
12-Hydroxystearic acid, a white to pale yellow waxy solid. The melting point is quite high, about 80-82 ° C. Because it has both hydroxyl groups and long-chain alkyl groups in its molecules, it has both hydrophilicity and lipophilicity. This unique structure endows it with special physical and chemical properties. It has good solubility in organic solvents, such as ethanol, ether, etc., but has less solubility in water. At the same time, the substance has good thermal stability, and at higher temperatures, it is not easy to decompose and deteriorate, and can maintain the stability of its own structure and properties.
2. Application
1. ** Lubrication field **: Due to the structural characteristics of 12-hydroxystearic acid, it can be used as a lubricant. During metal processing, applying a lubricant containing this substance can form a uniform and dense moisturizing film on the metal surface, effectively reducing the friction between the metal and the mold, reducing wear and improving the surface quality of the workpiece. For example, when rolling steel, adding an appropriate amount of 12-hydroxystearic acid lubricant can make the steel surface smoother and have higher dimensional accuracy.
2. ** Plastic industry **: It is an excellent plastic additive. Added to plastics, it can improve the processing performance of plastics, enhance its fluidity, and reduce processing temperature and pressure. At the same time, it can improve the flexibility and impact resistance of plastic products. Taking polyvinyl chloride (PVC) as an example, after adding 12-hydroxystearic acid, PVC products become softer and less brittle on the basis of maintaining their original strength, broadening their application range in packaging, building materials and other fields.
3. ** Cosmetics field **: Using its lipophilic and hydrophilic characteristics, it can be used as a cosmetic emulsifier. It can make the oil phase and water phase mix evenly to form a stable emulsion system. In skin care products such as creams and lotions, 12-hydroxystearic acid helps to evenly disperse the active ingredients, improve the stability and feel of use of the product, and make it easier for the skin to absorb nutrients.
III. Production
1. ** Natural oil conversion method **: Natural oils are used as raw materials, such as castor oil. The main component of castor oil, glyceryl ricinoleate, can be obtained by hydrolysis reaction. Then through a series of reactions such as catalytic hydrogenation, the unsaturated double bond in ricinoleic acid is hydrosaturated, and then 12-hydroxystearic acid is obtained. This method has a wide range of raw materials and relatively low cost. However, the production process is relatively complicated, and multi-step reaction and refining processes are required to ensure product purity.
2. ** Chemical synthesis method **: Petrochemical products are used as starting materials and prepared through a series of organic synthesis reactions. For example, 12-hydroxystearic acid can be synthesized from butadiene, carbon monoxide and water through carbonylation reaction, hydrogenation reaction and subsequent treatment. The production process of this method is highly controllable, the product quality is stable, but it requires high equipment and technology, and some raw materials rely on petrochemical resources and are limited by resources and environmental factors.
To sum up, 12-hydroxystearic acid plays an important role in many fields due to its unique properties. Different production methods have their own advantages and disadvantages. It is necessary to choose the appropriate production method according to the actual needs to promote its wider application and development.
