    • Disclosed is a process for preparing a salt of a sulfurized alkyl-substituted hydroxyaromatic composition having a reduced content of unsulfurized alkyl-substituted hydroxyaromatic compound and its unsulfurized metal salt. The process involves at least the steps of: (a) providing a composition comprising (i) a salt of a sulfurized alkyl-substituted hydroxyaromatic compound; (ii) an unsulfurized alkyl-substituted hydroxyaromatic compound and (iii) an unsulfurized metal salt of the alkyl-substituted hydroxyaromatic compound; wherein the alkyl-substituted hydroxyaromatic compound is derived from alkylation of a hydroxyaromatic compound with one or more olefins comprising C9 to C18 oligomers of monomers selected from propylene, butylene or mixtures thereof; and (b) extracting the unsulfurized alkyl-substituted hydroxyaromatic compound and its unsulfurized metal salt from the composition of step (a) with one or more solvents capable of solubilizing the unsulfurized alkyl-substituted hydroxyaromatic compound and its unsulfurized metal salt and under extraction conditions sufficient to provide a salt of a sulfurized alkyl-substituted hydroxyaromatic composition having a reduced content of unsulfurized alkyl-substituted hydroxyaromatic compound and its unsulfurized metal salt.
    • 公开了一种制备具有降低的未硫化烷基取代的羟基芳族化合物及其未硫化金属盐含量的硫化烷基取代的羟基芳族化合物的盐的方法。 该方法至少包括以下步骤:(a)提供包含(i)硫化烷基取代的羟基芳族化合物的盐的组合物; (ii)未硫化烷基取代的羟基芳族化合物和(iii)烷基取代的羟基芳族化合物的未硫化金属盐; 其中烷基取代的羟基芳族化合物衍生自羟基芳族化合物与一种或多种烯烃的烷基化,所述烯烃包含选自丙烯,丁烯或其混合物的单体的C 9至C 18低聚物; 和(b)从步骤(a)的组合物中提取未硫化的烷基取代的羟基芳族化合物及其未硫化金属盐与一种或多种能够溶解未硫化烷基取代的羟基芳族化合物及其未硫化金属盐的溶剂,并在提取条件下足够 提供具有降低的未硫化烷基取代的羟基芳族化合物含量及其未硫化金属盐的硫化烷基取代的羟基芳族组合物的盐。

    • Disclosed herein is a post-treated salt of a sulfurized alkyl-substituted hydroxyaromatic composition which is a reaction product of (a) a salt of a sulfurized alkyl-substituted hydroxyaromatic composition, wherein the alkyl-substituted hydroxyaromatic compound is derived from alkylation of a hydroxyaromatic compound with one or more olefins comprising C9 to C18 oligomers of monomers selected from propylene, butylene or mixtures thereof, (b) a source of an aldehyde and (c) a primary and/or secondary monoamine compound having at least one active hydrogen. The post-treated salt of a sulfurized alkylhydroxyaromatic composition disclosed herein has a reduced content of unsulfurized alkyl-substituted hydroxyaromatic compound and its unsulfurized metal salt as compared to the content, by combined mass, of the unsulfurized alkyl-substituted hydroxyaromatic compound and its unsulfurized metal salt present in the non-post-treated salt of a sulfurized alkyl-substituted hydroxyaromatic composition.
