Capacitor Dielectric Fluid
Benzyl toluene insulating oil, an insulation fluid centered around benzyl toluene, is mainly applied to insulate and cool electrical equipment. Given its outstanding electrical insulation features and thermal stability, it finds extensive application in high - voltage transformers and cables. The chemical properties of benzyl toluene guarantee its stability in high - temperature and humid conditions, thus prolonging the service life of power equipment.
Product Details：Capacitor Dielectric Fluid
The employment of benzyl toluene insulating oil in capacitors shows its outstanding insulation properties. Compared to traditional capacitor oils, it not only offers enhanced electrical insulation but also has remarkable thermal management capabilities. Owing to its chemical stability, this insulating oil can work extremely well in high - temperature and humid environments. Consequently, it effectively extends the life of capacitors and upgrades the overall performance of the equipment.

1. Performance Characteristics
Capacitor oil usually features a dielectric strength above 30 kV/mm, effectively preventing current from leaking. Its low dielectric constant and loss factor make it suitable for high - frequency operations. It has strong antioxidant and hydrolysis - resistance properties, and during long - term usage, it can preserve its physical and chemical properties. Since it barely reacts with the moisture and oxygen in the air, the chance of oil degradation is reduced.
2. Analysis of the Synthesis Method of Benzyltoluene
Synthesis by using Lewis acid as the catalyst: In the synthesis method which uses Lewis acid as the catalyst, the catalysts mainly involve metal halides such as AlCl3, FeCl3, ZnCl2 and GaCl3. This method was developed by Hess in Germany during the 1960s. When AlCl3 was used as the catalyst, the synthesis experiment of benzyltoluene was carried out at 60 - 70 ℃. Monobenzyltoluene, separated by distillation from the reaction product, reacted with benzyl chloride to produce dibenzyltoluene, and the yield was 84% of the theoretical value.
