专利汇可以提供Manufacture of innovative electricity insulation oil substance专利检索，专利查询，专利分析的服务。并且PURPOSE: To restrain deposition of crystals while maintaining low viscosity at low temperatures by distilling a reaction product containing benzyl toluene and ditolyle methane to make a composite substance made up with 20W80% of benzyl toluene and 80W20% of ditolyle methane.
CONSTITUTION: Toluene, and benzyl toluene or diphenyl methane manufactured not starting from chlorinated hydrocarbon which is benzine chloride are made to react under the presence of heterogeneous catalyst at temperatures of -10 to 550°C. For the heterogeneous catalyst, a catalyst chosen from a group consisting of Lewis acid, solid acid, heteropoly acid, and an ion exchange resins of extra-strong acid and strong acid type is used. From the reaction product obtained containing benzyl toluene and ditolyle methane, an electricity insulation oil composite substance is produced by distilling the reaction product so that the composite substance consists of 20W80% of benzyl toluene and 80W20% of ditolyle methane. With this procedure, an electricity insulating oil composite substance without substantially containing no chlorine is obtained while restraining the deposition of crystals and maintaining low viscosity at low temperatures.
