摘要： 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. This acid may be a free acid chloride, a fatty acid, a carboxylic acid anhydride, or combination thereof. The resulting functionalized 12-hydroxy stearic acid exhibits improved thermoxidative capability, low temperature flowability, and increased fire point.

摘要： 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.

摘要： An electrical insulating oil which can be produced easily at low cost, scarcely contains undesirable components of tarry substance, unsaturated compounds and carbonyl compounds, does neither swell nor dissolve plastic materials, and has excellent electrical properties. The electrical insulating oil is characterized in that it comprises a fraction having boiling points in the range of 270.degree. to 350.degree. C. which is prepared by distilling the heavier products obtained from the process for producing ethyltoluene by alkylating toluene with ethylene in the presence of synthetic zeolite catalyst. Included also in the present invention are oil-filled electrical appliances that are produced by impregnating them with the above insulating oil.
