Abstract

Aceite lubricante que comprende una mezcla aditiva de materiales base de aceites lubricantes y complejos alcohol éster de alta viscosidad y lubricantesque los comprenden. El aceite lubricante comprende una mezcla aditiva de los siguientes componentes: (A) un material base de un complejo alcohol éster quecomprende el producto de reaccion de una mezcla aditiva que tiene lo siguiente: (1) un compuesto polihidroxilo representado por la formula general:: R(OH)ndonde R es cualquier grupo hidrocarbilo alifático o cicloalifático, y n es por lo menos 2, con la condicion de que dicho grupo hidrocarbilo contenga desdeaproximadamente 2 a 20 átomos de carbono; (2) un ácido polibásico o un anhídrido de un ácido polibásico con la condicionde que la relacion deequivalentes de dicho ácido polibásico a equivalentes de alcohol de dicho compuesto polihidroxilo esté dentro del rango de entre aproximadamente 1,6:1a 2:1; y (3) un alcohol monohídrico, con la condicion de que la relacionde equivalentes de dicho alcohol monohídrico a equivalentes de dicho ácidopolibásico esté en el rango de entre aproximadamente 0,84:1 a 1,2:1; donde dicho complejo alcohol éster exhibe una viscosidad en el rango de entreaproximadamente 100-700 cSt a 40°C, y tiene una concentracion de éster de ácido polibásico de menos de o igual a 70% en peso basado en dicho complejoalcohol éster; y (B) por lo menos un material base adicional.Lubricating oil that comprises an additive mixture of base materials of lubricating oils and high viscosity alcohol ester complexes and lubricants that comprise them. The lubricating oil comprises an additive mixture of the following components: (A) a base material of an alcohol ester complex comprising the reaction product of an additive mixture having the following: (1) a polyhydroxyl compound represented by the general formula: R (OH) n where R is any aliphatic or cycloaliphatic hydrocarbyl group, and n is at least 2, provided that said hydrocarbyl group contains from about 2 to 20 carbon atoms; (2) a polybasic acid or an anhydride of a polybasic acid with the proviso that the ratio of equivalents of said polybasic acid to alcohol equivalents of said polyhydroxyl compound is within the range of between about 1.6: 1 to 2: 1; and (3) a monohydric alcohol, provided that the ratio of equivalents of said monohydric alcohol to equivalents of said polybasic acid is in the range of between about 0.84: 1 to 1.2: 1; wherein said alcohol ester complex exhibits a viscosity in the range of about 100-700 cSt at 40 ° C, and has a polybasic acid ester concentration of less than or equal to 70 wt% based on said ester alcohol complex; and (B) at least one additional base material.
