Beschreibung
Zusammenfassung:The present invention discloses with the development of ecofriendly and biodegradable lubricant formulation useful for micro electro mechanical systems and process thereof. The new generation Mineral oil free lubricant formulations were developed by esterification of polyols such as 2,2-dimethyl, 1,3-Propanediol, 2,2-diethyl-1,3-propane diol, and aliphatic di carboxylic acids like adipic and azelaic and with mono alcohol, using heterogeneous catalyst Indion 140 with cation exchange properties. The said formulation has a viscosity in the range of 31 to 47 cSt at 40° C., a high viscosity index of 139-196, pour point of approximately
