Abstract

SULFONATOS DE MAGNESIO SOBREBASADOS QUE TIENEN RESISTENCIA AUMENTADA A INTERACCIONES. SE PREPARAN DE ACIDOS SULFONICOS PREPARADOS DE ALQUILATOS CON GRUPOS ALQUILOS DE CADENA LARGA Y MEDIA. COMPUESTOS QUE COMPRENDEN TAL SULFONATO DE MAGNESIO SOBREBASA Y PARTICULARMENTE SON APROPIADOS PARA USAR EN COMBINACION CON DISPERSANTES Y/O MODIFICANTES DE FRICCION DE ALTO PESO MOLECULAR. PUEDEN PREPARARSE COMPOSICIONES ESTABLES LIBRES DE SEDIMENTOS DE ACEITES LUBRICANTES (INCLUYENDO SUS CONCENTRADOS Y LUBRICANTES) QUE PUEDEN ENCONTRAR REQUERIMIENTOS ECONOMICOS DE CUALIDAD SG Y EL FUEL TIER II.
