Preparation and properties evaluation of biolubricants derived from canola oil and canola biodiesel.

This study demonstrates the evaluation and comparison of the lubricity properties of the biolubricants prepared from the feed stocks such as canola oil and canola biodiesel. Biolubricant from canola biodiesel has a low cloud and pour point properties, better friction and antiwear properties, low phase transition temperature, is less viscous, and has the potential to substitute petroleum-based automotive lubricants. Biolubricant from canola oil has high thermal stability and is more viscous and more effective at higher temperature conditions. This study elucidates that both the biolubricants are attractive, renewable, and ecofriendly substitutes for the petroleum-based lubricants.
