  • Patent number: 10256007
    Abstract: The present invention provides a process to extract liquid dielectric coolant from the sesame oil, which is suitable for both power frequency and high frequency electrical applications. The process comprises the steps of, processing the refined, bleached and deodorised sesame seed oil with an alkali to remove the fatty acids. After processing the sesame seed oil, at step, the processed sesame seed oil is blended with a Sodium Hydroxide (NaOH) solution. The blended sesame oil forms a top layer and a bottom layer within short duration of time. At step, the top layer is extracted and is water washed and filtered. At step, the top layer sesame seed oil is mixed the Tert Butyl Hydroxy Quinone solution. Finally, at step, the mixture of filtered top layer and Tert Butyl Hydroxy Quinone solution is heated to extract the liquid dielectric coolant.
