| Description |
Increasing environmental awareness and regulations have accelerated the developmental
activity of rapid biodegradable lubricants in some part of the globe in last few years.
Biodegradable products carry a significant price premium over conventional mineral oils.
Ester based products are generally compatible with most construction materials, and also
used as environmentally acceptable t1uids in high performance lubricants.
Polyol esters are gaining importance because of their inherent good oxidation, better
thern;tal stability and low volatility prop~rties as compared to mineral oils. Coupled with
their higher t1ash point and auto-ignition temperature; low order of toxicity for vapor
inhalation, ingestion and skin irritation along with high biodegradability, these are safe
for lubricant formulations with lesser impact on environment.
Ion exchange resins are found to be efficient catalyst for the synthesis of various types of
biodegradable/ecofriendly esters. The physicio-chemical properties of the esters
synthesized from 2,2-dimethyll,3-propane diol, 2,2-diethyll,3-propane diol,l,l,l-tris
hydroxy methyl propane and C5-C10 dicarboxylic acids with mono alcohol have been
determined to evaluate their suitability as synthetic lubricating oil base stocks. The paper
highlights the results of these complex esters.
