Abstract
Procedimiento para la preparación de una fracción de aceite mineral estable frente al envejecimiento, que cumple las especificaciones de índices característicos según la norma DIN 51.507 , y es apropiada como aceite para transformadores, convertidores, conmutadores, interruptores, y como aceite aislante eléctrico, y que consiste en el producto refinado desparafinado de al menos un petróleo crudo y en pequeñas porciones de un extracto obtenido en la refinación de productos destilados de petróleo, caracterizado porque a partir de un petróleo crudo de base parafínica se separa una fracción de producto destilado con un margen de ebullición de 270-400ºC, especialmente 300-355ºC, una viscosidad de 6-25 cSt, especialmente 10-12 cSt, a 20ºC, así como un punto de inflamación, según Marcusson, de al menos 130ºC, se desparafina de modo usual, y mediante una refinación con disolventes en sí conocida se refina con un disolvente selectivo para hidrocarburos aromáticos de manera tal que se obtenga por lo menos aproximadamente 70% en peso de un solvato.
