VEGETABLE DIALECTIC FLUID METHOD THEROF AND ELECTRIC POWER MACHINE COMPRISING THE SAME

摘要

More particularly, the present invention relates to a vegetable insulated fluid and a method for producing the vegetable insulated fluid, which comprises esterifying a vegetable mixed fatty acid containing a linear or branched fatty acid having 7 to 10 carbon atoms and a linear or branched fatty acid having 12 to 20 carbon atoms with diglycerol Wherein the diglycerol esterified product has a pour point of less than -40 캜 and a flash point of 300 캜 or higher, and a solid acid catalyst to produce a vegetable insulation fluid And a power device using the vegetable insulating fluid. According to the present invention, the vegetable-insulating fluid has an effect of exhibiting excellent insulation characteristics that are environmentally friendly and usable in a wide temperature range. Such a vegetable-insulating fluid can be produced at a high yield using a solid acid catalyst having excellent selectivity and activity have.
