Fluorinated Dielectric Liquid for Capacitors
Benzyltoluene insulating oil is mainly composed of benzyltoluene isomers. It is based on toluene as raw material, through a specific chemical reaction to introduce the benzyl group into the toluene molecule to form benzyltoluene compounds with different structures, usually a mixture of mono-benzyltoluene and dibenzyltoluene.
Product Details：Fluorinated Dielectric Liquid for Capacitors
Benzyltoluene is a high - temperature synthetic heat - transfer oil with favorable thermal stability, oxidation resistance, and a low condensation point. It is widely utilized in numerous gas - phase baking facilities for food, in spraying operations, and in non - woven fabric production. Besides, it can be used to achieve low - temperature cooling.

1. Application Areas
Electronic capacitors: In all sorts of electronic equipment such as cell phones, computers, TVs, and stereos, electronic capacitors are vital components. Capacitor oil is used within electronic capacitors. By using capacitor oil, the performance of capacitors can be improved. This allows capacitors to store and release charge steadily and perform functions such as filtering, coupling, and bypassing, thus guaranteeing the proper operation of electronic devices.
2. Analysis of the Synthesis Method of Benzyltoluene
Synthesis using Lewis acid as a catalyst：The improvement of the method is mostly focused on the simplification of post-treatment: toluene benzylation experiments were carried out at 100 ℃ using ferric chloride as the catalyst, and the crude product was directly dechlorinated using sodium methanol at 220-320 ℃ after distillation of toluene at the end of the reaction, followed by direct flash evaporation to separate mono- and dibenzyltoluene, and multi-benzyltoluene was released from the bottom of the tower as the kettle liquid together with the dechlorinator and the residue of the catalyst. This method eliminates the step of washing to remove the ferric chloride catalyst, avoids the generation of large amounts of wastewater and simplifies the post-treatment process.
