1. Performance Characteristics
Capacitor oil typically has a dielectric strength exceeding 30 kV/mm, which enables it to effectively prevent current leakage. Additionally, its extremely low dielectric constant and loss factor make it highly suitable for high - frequency applications. Moreover, it possesses strong antioxidant and hydrolysis - resistant properties, allowing it to maintain its physical and chemical properties during long - term use. Since it doesn't react easily with moisture and oxygen in the air, the likelihood of oil degradation is reduced.
2. Analysis of the Synthesis Method of Benzyltoluene
Synthesis using Lewis acid as a catalyst：The catalysts used in the synthesis method with Lewis acid as the catalyst mainly include metal halides such as AlCl3, FeCl3, ZnCl2 and GaCl3. This method was developed by Hess in Germany in the 1960s: using AlCl3 as catalyst, the synthesis experiment of benzyltoluene was carried out at 60-70 ℃, and dibenzyltoluene obtained by adding benzyl chloride to the reaction product monobenzyltoluene separated by distillation was added to the reaction with a yield of 84% of the theoretical value.
