摘要：
本发明公开的是硫化烷基羟基芳族化合物的中性或过碱性盐，其通过包括以下步骤的方法得到：(a)硫化烷基羟基芳族化合物以提供硫化烷基羟基芳族反应产物，所述烷基羟基芳族化合物得自羟基芳族化合物用一种或多种烯烃的烷基化，所述烯烃包含选自丙烯、丁烯或它们的混合物的单体的C9-C18低聚物；(b)从步骤(a)的所述硫化烷基羟基芳族反应产物中除去任何未硫化烷基羟基芳族化合物，以得到基本上不含未硫化烷基羟基芳族化合物的硫化烷基羟基芳族化合物；和(c)中和步骤(b)的所述硫化烷基羟基芳族化合物，以提供所述硫化烷基羟基芳族化合物的盐，其中所述硫化烷基羟基芳族化合物的所述过碱性盐含有小于约2％的所述未硫化烷基羟基芳族化合物及其未硫化金属盐的总质量。
摘要（英）：

Disclosed herein is a neutral or overbased salt of a sulfurized alkylhydroxyaromatic compound obtained by the process comprising the steps of (a) sulfurizing an alkylhydroxyaromatic compound 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 to provide a sulfurized alkylhydroxyaromatic reaction product; (b) removing any unsulfurized alkylhydroxyaromatic compound from the sulfurized alkylhydroxyaromatic reaction product of step (a) to obtain a sulfurized alkylhydroxyaromatic compound substantially free of the unsulfurized alkylhydroxyaromatic compound; and (c) neutralizing the sulfurized alkylhydroxyaromatic compound of step (b) to provide a salt of the sulfurized alkylhydroxyaromatic compound, wherein the overbased salt of the sulfurized alkylhydroxyaromatic compound contains less than about 2% by combined mass of the unsulfurized alkylhydroxyaromatic compound and its unsulfurized metal salt.
