20140252281SYNTHETIC ESTER-BASED DIELECTRIC FLUID COMPOSITIONS FOR ENHANCED THERMAL MANAGEMENT - A dielectric fluid composition for electrical apparatus comprises a functionalized methyl-12-carboxy methyl stearate having desirable properties including a pour point less than −30° C. and a fire point greater than 250° C. It may be prepared by a process wherein methyl-12-hydroxy methyl stearate is transesterified by reaction with a C3-C20 alcohol to form the hydroxy methyl ester, followed by reaction with a linear or branched C4-C20 carboxylic acid selected from free acid chlorides, fatty acids, carboxylic acid anhydrides, and combinations thereof. The second step serves to end-cap the hydroxyl groups, thereby producing the functionalized methyl-12-carboxy methyl stearate compound that exhibits improved thermoxidative stability and low temperature flowability, as well as increased fire point.09-11-2014
20140319435High Purity Dielectric Vegetable Oil, and A Method for Obtaining the same and it's Use in Electric Apparatuses - A dielectric high purity vegetable oil—free from antioxidants and/or external additives to be used in electric equipment such as transformers, as isolating element and as cooling means and a method for obtaining the same in which the dielectric high purity vegetable oil—is obtained by means of the optimization of the bleaching steps—and deodorizing—from the Refining process—known as Modified Caustic Refining Long-Mix (RBD).10-30-2014
20140346414DIELECTRIC FLUID COMPOSITIONS FOR ENHANCED THERMAL MANAGEMENT - A dielectric fluid composition for electrical apparatus comprises a functionalized 12-hydroxy stearic acid having desirable properties including a pour point less than −30° C. and a fire point greater than 250° C. It may be prepared by a process wherein 12-hydroxy methyl stearate is transesterified by reaction with a C3-C20 alcohol to form an alkyl-12-hydroxy stearate, followed by esterification thereof with a linear or branched C4-C20 carboxylic acid.
