Blend of Extracts of Hibiscus Flowers and Used Cooking Oil as Bio-Lubricant 2020-28-0523
The mineral oil based conventional lubricants are consumed more and hence they get depleted rapidly. The environmental issues and non-biodegradability of mineral oil necessitates the search for an alternative lubricant. The present work deals with the development of a bio-lubricant by blending extracts of hibiscus flowers in used cooking oil. The addition of extracts of hibiscus flowers enhances the viscosity and tribological characteristics of the used cooking oil. The developed bio-lubricant exhibits excellent physicochemical properties also. These results show the potential of developed bio-lubricant as a substitute for the mineral oil.
