Physical and Chemical Properties of Mahua and Sal Seed Oils

摘要

Bio-lubricants are the emerging outcomes of the vegetable oils that can be used for several applications in machines and engines. They are very much helpful for providing the frictionless wear and tear operations under certain operating and controlling conditions of machines. Researches have focused in the study and analysis of the tribiological characteristics of the vegetable oils. Some vegetable oils are edible, and some are no edible. This chapter focuses on the characteristics of vegetable oils specifically non-edible oils which are great source of bio-lubricants. The petroleum production and final composition in lubricants contain 60-99% base oil and the remaining as additives, based on the desired performance. The main focus of study is carried on mahua and sal seed oils. The oils can be used in electrical machines, mechanical systems and rotary mills. The comparative study is also carried for mahua, coconut, palm, sal, neem, olive, castor, canola, cashew nut and jatropha.
