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&#xb0; C., a high viscosity index of 139-196, pour point of approximately &#x3c;&#x2212;39&#xb0; C. with a multifunctional EP additive of recommended dose of 1.5-4%. These new generation lubricants exhibited excellent biodegradability, a high viscosity index, and a low pour point, a high flash point, good lubricity, good oxidative stability, very good protection, against wear, no evaporation loss, good adherence to metal, corrosion inhibiting characteristics and suitability for use with commercial additives. In addition the products are non toxic to the sewage bacteria.

Ecofriendly and biodegradable lubricant formulation and process for preparation thereof

The present invention relates to a process for the conversion of a low molecular weight polymeric byproduct obtained during production of high density polyethylene (HDPE), commonly known as low polymer wax (LPW) or polymer mud, into different products like different grades of paraffin wax, microcrystalline wax, lube and grease base stocks by a process comprising of thermal treatment in an inert atmosphere in the presence of organic peroxides or hydroperoxides and metal oxides. The end product depends upon the suitable selection of various process parameters like type of peroxides or hydroperoxides, metal oxides, temperature and duration of reaction.
