Pressure sensitive Dye Solvent
Benzyl toluene insulating oil is an insulation fluid based on benzyl toluene, primarily used for the insulation and cooling of electrical equipment. Its excellent electrical insulation properties and thermal stability make it widely used in high-voltage transformers and cables. The chemical properties of benzyl toluene ensure its stability in high-temperature and humid environments, extending the lifespan of power equipment.
Product Details：Pressure sensitive Dye Solvent
Benzyl toluene insulating oil's use in capacitors demonstrates its extraordinary insulation properties. When compared with traditional capacitor oils, it not only provides better electrical insulation but also has excellent thermal management capabilities. Because of its chemical stability, this insulating oil can perform remarkably in high - temperature and humid settings. This effectively increases the lifespan of capacitors and improves the overall performance of the equipment.

1. Performance Characteristics
Concerning thermal stability, it can maintain satisfactory insulation performance even in high - temperature (above 100 °C) and extreme environments. The high flash point effectively reduces the risk of fire. In terms of environmental characteristics, new capacitor oils like benzyl toluene insulating oil usually have more outstanding environmental performance. Their low volatility and high biodegradability minimize the impact on the environment. They conform to international environmental standards and are in tune with the trend of green power development.
2. Analysis of the Synthesis Method of Benzyltoluene
Synthesis with the use of Lewis acid as a catalyst: The catalysts utilized in the synthesis method with Lewis acid functioning as the catalyst are mainly metal halides such as AlCl3, FeCl3, ZnCl2 and GaCl3. Developed by Hess in Germany in the 1960s, this method adopted AlCl3 as the catalyst. The synthesis experiment of benzyltoluene was carried out at 60 - 70 ℃. After separating monobenzyltoluene from the reaction product by distillation, benzyl chloride was added to react with it to obtain dibenzyltoluene, with a yield of 84% of the theoretical value.
