Benefits of Dibasic ester in Engine Oils:
Volatility:
The polarity of Dibasic ester molecules causes them to be attracted to one another and this intermolecular attraction requires more energy (heat) for the esters to transfer from a liquid to a gaseous state.
Therefore, at a given molecular weight or viscosity, the esters will exhibit a lower vapor pressure which translates into a higher flash point and a lower rate of evaporation for the lubricant.
Generally speaking, the more ester linkages in a specific ester, the higher Dibasic ester’s flash point and the lower its volatility.
Lubricity:
Polarity also causes Dibasic ester molecules to be attracted to positively charged metal surfaces.
As a result, the molecules tend to line up on the metal surface creating a film which requires additional energy (load) to penetrate. The result is a stronger film which translates into higher lubricity and lower energy consumption in lubricant applications.
Detergency/Dispersency:
The polar nature of Dibasic ester also makes them good solvents and dispersants.
This allows the esters to solubilize or disperse oil degradation by-products which might otherwise be deposited as varnish or sludge, and translates into cleaner operation and improved additive solubility in the final lubricant.
Biodegradability:
While stable against oxidative and thermal breakdown, the ester linkage provides a vulnerable site for microbes to begin their work of biodegrading the ester molecule.
This translates into very high biodegradability rates for ester lubricants and allows more environmentally friendly products to be formulated.
Characteristics of Dibasic Ester:
