What are the characteristics of Dioctyldecyl Sebacate?
Dioctyldecyl sebacate (Dioctyldecyl Sebacate), with several characteristics. Its appearance is often clear and colorless to light yellow liquid, uniform texture, no visible impurities, this is a visually observable characteristic.
In terms of solubility, the substance exhibits good solubility in many organic solvents, such as aromatics, chlorinated hydrocarbons, etc., and can be miscibly formed with it to form a homogeneous system. This property makes it flexible in various formulations.
Its viscosity is moderate, neither too viscous to cause poor fluidity, nor too dilute to maintain a specific form. Such a moderate viscosity is conducive to the processing process, whether it is mixing, coating or perfusion, etc., it can be carried out smoothly.
Thermal stability is quite excellent. It can maintain the stability of its own chemical structure and physical properties within a certain temperature range, and it is not easy to decompose or deteriorate even when heated. This characteristic makes it advantageous in application scenarios related to high temperature environments.
And it has low volatility. Under normal conditions, it is rarely lost due to volatilization, which helps to maintain the long-term effectiveness and stability of the product. It is a key characteristic in products that need long-term storage or use.
Its chemical stability is also good, it can resist the erosion of many chemical substances, and it is not easy to chemically react with common acids and bases, thus ensuring its use efficiency in complex chemical environments.
What is the production process of Dioctyldecyl Sebacate?
The process of making dioctyl decyl sebacate is a delicate and complicated process. At the beginning, it is necessary to choose high-quality sebacic acid and octyl decanol as materials. The purity of the two is related to the quality of the product.
The selected sebacic acid and octyl decanol are poured into a reactor equipped with a stirrer, thermometer and reflux device in a specific ratio. Then, an appropriate amount of catalyst is added, which can promote the rate of reaction and enable the two to combine more quickly and efficiently. Common catalysts include sulfuric acid, p-toluenesulfonic acid, etc. The dosage needs to be precisely controlled, and most may cause side reactions, and at least the reaction is slow.
Place the reactor on the heating device and slowly raise the temperature. Temperature control is crucial. In the initial stage, the temperature should be raised slowly to allow the material to be evenly heated and fully mixed. When the temperature reaches a certain temperature, about 180-220 degrees Celsius, the reaction intensifies. It is necessary to pay close attention to the temperature change and do not make the temperature fluctuate greatly to ensure the stable progress of the reaction. During this process, there will be an esterification reaction. Sebacic acid interacts with octyl decanol to remove water molecules and gradually form dioctyl decyl sebacate.
During the reaction, the agitator continues to operate to mix the materials evenly to avoid local overheating or uneven reaction. And through the reflux device, the volatile alcohols in the reaction can be recovered, and the utilization rate of raw materials can be improved.
When the reaction reaches the expected level, the acid value of the reaction solution drops to a certain standard, depending on the reaction process, it may take a few hours or even tens of hours. At this time, stop heating, and when the material in the reactor is slightly cold, move it to the neutralization device. Use alkaline substances, such as sodium carbonate solution, to neutralize the acidic substances in the reaction solution, so that the pH value is nearly neutral.
After neutralization, the washing process is carried out to remove the remaining catalysts, unreacted acids and salts and other impurities in the material. Wash several times until the washing water is clear and the water quality is tested qualified.
Subsequently, the washed material is moved to a distillation unit and distilled under reduced pressure. By distillation, unreacted alcohols and low boiling point impurities are separated to obtain pure dioctyl decyl sebacate. Finally, after cooling, filtration and other post-processing processes, the product is formed and can be packaged and stored.
What are the advantages of Dioctyldecyl Sebacate compared to other similar products?
Today there is Dioctyldecyl Sebacate. What are the advantages compared to other seemingly similar products? Let me tell you.
Dioctyldecyl Sebacate has excellent cold resistance. In cold winter, other products may become stiff due to low temperature and lose their flexibility. However, Dioctyldecyl Sebacate can still maintain good flexibility and can operate freely in extremely cold environments without affecting the performance of related devices or materials.
Furthermore, its compatibility with various materials is quite good. Whether mixed with polymer or blended with other additives, it can be uniformly dispersed without the risk of phase separation. This characteristic makes the product made from it more uniform and stable in performance and high quality.
And its volatility is extremely low. Ordinary similar products, at a certain temperature and time, easily dissipate some ingredients, resulting in product performance changes. Dioctyldecyl Sebacate is not the case. It can maintain the stability of the ingredients for a long time, so that the product can last for a long time to play the established effect and prolong the service life.
In addition, Dioctyldecyl Sebacate exhibits good processing performance during processing. It can help the production process to be smoother, improve production efficiency, and make the product look smooth and flawless. From this point of view, Dioctyldecyl Sebacate has many significant advantages compared to other similar products.
