Basic properties and benefits of biolubricant
...The term biolubricants applies to all lubricants that are both rapidly biodegradable and non‐toxic to humans and aquatic environments. A biolubricant may be plant oil‐based (e.g., rapeseed oil) or derived from synthetic esters manufactured from modified renewable oils or from mineral oil‐based products 18, 20. Table 4 summarizes some of the benefits of biolubricants...
...The chemical modification of plant oils by addition reactions to the double bonds constitutes a promising manner of obtaining valuable commercial products from renewable raw materials. In order to use plant oil‐based lubricants with special additives, chemical modifications, de novo synthesis, breeding, and/or biotechnology play an important role. These methods improve the performance and stability of base oils in lubricating formulations...
The so called "Bio-Lubricants" today are actually mixtures of GroupIV, Group V esters, and bio-based oils.
Virgin vegetable oils cannot be used in an IC engine.
