过碱性且硫化的烷基化羟基芳族化合物的盐的制备方法
摘要：
公开了一种过碱性且硫化的至少一种烷基化羟基芳族化合物的盐，其中所述羟基芳族化合物的烷基取代基是具有约15-约99wt.%分支的至少一种异构化烯烃的残基。所述过碱性且硫化的至少一种烷基化羟基芳族化合物的盐通过如下方法进行制备，该方法包括：(a)用具有约15-约99wt.%分支的至少一种异构化烯烃将至少一种羟基芳族化合物烷基化以提供至少一种烷基化羟基芳族化合物，所述异构化烯烃通过使具有约10-约40个碳原子的至少一种正构α-烯烃异构化而获得；(b)以任何顺序将所述烷基化羟基芳族化合物进行中和与硫化以提供至少一种中和且硫化的烷基化羟基芳族化合物；以及(c)将所述至少一种中和且硫化的烷基化羟基芳族化合物过碱化。
摘要（英）：

An overbased, sulfurized salt of at least one alkylated hydroxyaromatic compound, wherein the alkyl substituent of the hydroxyaromatic compound is a residue of at least one isomerized olefin having from about 15 to about 99 wt. % branching is disclosed. The overbased, sulfurized salt of at least one alkylated hydroxyaromatic compound is produced by the process comprising: (a) alkylating at least one hydroxyaromatic compound with at least one isomerized olefin having from about 15 to about 99 wt. % branching obtained by isomerizing at least one normal alpha olefin having from about 10 to about 40 carbon atoms, to provide at least one alkylated hydroxyaromatic compound; (b) neutralizing and sulfurizing the alkylated hydroxyaromatic compound in any order to provide at least one neutralized, sulfurized alkylated hydroxyaromatic compound; and (c) overbasing the at least one neutralized, sulfurized alkylated hydroxyaromatic compound.
