An aqueous based drilling fluid that exhibits improved lubricity, containing a phospholipid lubricant component and methods of improving the lubricity of an aqueous based drilling fluids. The methods include improving the lubricity of an aqueous based drilling fluid composed of an aqueous base fluid, and a weighting agent, with the addition of an effective amount of a phospholipid to substantially reduce the coefficient of friction when compared to the fluid absent the phospholipids.

Method for increasing lubrication in metal working processes by the use of phosphate esters of propoxylated and ethoxylated alcohols.

Method for increasing lubrication in metal working processes by the use of phosphate esters of propoxylated and ethoxylated alcohols.

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 <−39° 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.
