The product, High Quality dibenzyltoluene with CAS number 26898 - 17 - 9, is a chemical compound known for its excellent thermal stability and high boiling point. Its chemical formula is C₂₀H₂₀. Dibenzyltoluene appears as a clear, colorless to slightly yellow liquid under normal conditions.
It has a molecular weight of approximately 260.37 g/mol. The density of dibenzyltoluene is around 1.02 g/cm³ at 20°C. It has a boiling point in the range of 390 - 400°C, which makes it suitable for high - temperature applications. The flash point is quite high, typically above 170°C, ensuring a certain level of safety during storage and handling.
1. Heat transfer fluid: Due to its high thermal stability, dibenzyltoluene is widely used as a heat transfer fluid in various industrial processes. It can efficiently transfer heat in systems operating at high temperatures, such as in chemical reactors, food processing plants, and solar thermal power plants.
2. Solvent: It serves as a good solvent in the production of some specialty chemicals and polymers. Its non - polar nature allows it to dissolve a variety of organic compounds, facilitating chemical reactions and product purification.
3. Insulating oil: In the electrical industry, dibenzyltoluene can be used as an insulating oil in transformers and other electrical equipment. Its high dielectric strength and thermal stability help to maintain the performance and safety of electrical systems.
1. Storage: Store dibenzyltoluene in a cool, dry, and well - ventilated area away from direct sunlight and heat sources. Keep the container tightly closed when not in use to prevent evaporation and contamination.
2. Handling: When handling the product, wear appropriate personal protective equipment (PPE), including chemical - resistant gloves, safety goggles, and a lab coat. Avoid contact with skin, eyes, and clothing. In case of accidental contact, immediately rinse the affected area with plenty of water and seek medical attention if necessary.
3. Application: For heat transfer applications, ensure that the system is clean and free of contaminants before filling with dibenzyltoluene. Monitor the temperature and pressure of the system regularly during operation to ensure optimal performance. When using it as a solvent or insulating oil, follow the standard operating procedures of the specific process.
1. Chemical reactor: In a large - scale chemical manufacturing plant, dibenzyltoluene was used as a heat transfer fluid in a reactor where a high - temperature reaction was taking place. The plant had previously used other heat transfer fluids that were prone to thermal degradation at the required reaction temperature. After switching to dibenzyltoluene, the reactor's efficiency increased significantly. The stable heat transfer performance ensured consistent reaction conditions, resulting in a higher quality and yield of the final product. The maintenance cost of the heat transfer system also decreased as dibenzyltoluene's long - term stability reduced the frequency of fluid replacement and equipment cleaning.
2. Solar thermal power plant: A solar thermal power plant adopted dibenzyltoluene as its heat transfer fluid. The high boiling point of dibenzyltoluene allowed the plant to operate at higher temperatures, which increased the efficiency of the power generation process. The plant was able to produce more electricity with the same amount of solar energy input. Additionally, the excellent thermal stability of dibenzyltoluene ensured the long - term reliability of the heat transfer system, reducing downtime and maintenance requirements.
