    摘要: 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.

    摘要: Additives for internal combustion engines are provided which in fuels maintain cleanliness of intake system without contributing to combustion chamber deposits. The additives are hydrocarbyl methylol poly(oxyalkylene) amino ethanes comprising a hydrocarbyl-terminated methylol poly(oxyalkylene) chain of 2 to 4 carbon oxyalkylene units bonded to an ethane or substituted ethane chain in turn bonded to a nitrogen atom of an amine or polyamine having from 1 to 12 amine nitrogens and from 2 to 40 carbon atoms.
