TL;DR: In this article, the authors propose a method to synthesize a mixture of compounds useful as lubricant and fuel dispersants by reacting an intermediate (A) of the formulae where each R is hydrogen or a lower hydrocarbon-based group, Ar is an aromatic moiety having at least one aliphatic substituent of at least 6 carbon atoms and x is 1 to about 10, with an amino compound (B) which contains one or more amino groups having hydrogen bonded directly to an amino nitrogen.

TL;DR: In this paper, combinations of amino phenols, wherein said phenols contain a substantially saturated hydrocarbon substituent of at least 10 aliphatic carbon atoms, and one or more detergent/dispersants selected from the group consisting of (I) neutral or basic metal salts of an organic sulfur acid, phenol or carboxylic acid; (II) hydrocarbylsubstituted amines wherein the hydrocar-byl substituents is substantially alophatic and contains at least 12 carbon atoms; (III) acylated nitrogen-containing

TL;DR: In this paper, a hydroxyaromatic compound containing an aliphatic or alicyclic substituent which has at least about 6 carbon atoms with an aldehyde in the presence of an alkaline reagent and at a temperature up to about 125°C.

TL;DR: In this paper, a two-step method was proposed to obtain substituted carboxylic acids of the type prepared by the alkylation of maleic anhydride with an olefin polymer (e.g., polybutene).

TL;DR: In this article, the authors describe a SALICYCLIC ACID, or a SALT THEREOF, with SULFUR and an ALKALINE EARTH BASE at a temperature of about 150-250*C, in the presence of an ALKYLENE OR POLYALKYLENE GLYCOL OR a MONOETHER THEROF.
