    摘要: Additives for improving the low temperature flow properties and oxidative stability of hydrocarbon oils are disclosed, which comprise the condensation reaction product of alkylated phenol and sulfurizing agent, wherein:(a) the polymer composition has a number average molecular weight of at least about 3,000 and a molecular weight distribution of at least about 1.5;(b) in the alkylated phenol reactant the alkyl groups (i) are essentially linear; (ii) have between 6 and 50 carbon atoms; and (iii) have an average number of carbon atoms between about 12 and 26; and(c) not more than about 10 mole percent of the alkyl groups on the alkylated phenol have less than 12 carbon atoms and not more than about 10 mole percent of the alkyl groups on the alkylated phenol have more than 26 carbon atoms. The additives may also be produced in a branched backbone form in which monomer reactants are compolymerized with certain tri- or tetrafunctional comonomers. Blends of these additives with various hydrocarbon oils, and particularly various middle distillates and lubricating oil compositions, whose low temperature flow properties and oxidative stability are significantly improved thereby, are also disclosed.

    摘要: Essentially linear alkyl aromatics wherein the alkyl is attached to the aromatic ring at the .beta.-position are produced by the process wherein a linear hydrocarbon selected from the group consisting of linear .alpha.-olefins, linear .alpha.-substituted alkyl halides or linear .alpha.-substituted alkyl alcohol or mixtures of such olefins, halides or alcohols are reacted with an aromatic compound in the presence of an aprotic-polar cosolvent.

    摘要: Additives for improving the low temperature flow properties and oxidative stability of hydrocarbon oils are disclosed, which comprise the alkylation of a phenol in the presence of a dipolar aprotic cosolvent to produce an essentially linear alkylated phenol which is condensated with a sulphurizing agent to produce the low temperature flow improver wherein:(a) the polymer composition has a number average molecular weight of at least about 3,000 and a molecular weight distribution of at least about 1.5;(b) in the alkylated phenol reactant the alkyl groups (i) are essentially linear; (ii) have between 6 and 50 carbon atoms; and (iii) have an average number of carbon atoms between about 12 and 26; and(c) not more than about 10 mole percent of the alkyl groups on the alkylated phenol have less than 12 carbon atoms and not more than about 10 mole percent of the alkyl groups on the alkylated phenol have more than 26 carbon atoms.
