This invention relates to a composition containing: (a) a hydrocarbon fluid; and (b) a hydrocarbyl- and hydroxy-substituted aromatic condensate comprising the reaction product of: (1) at least 75 mole percent based on the total amount of (b)(1) and (b)(2) of a hydrocarbyl- and hydroxy-substituted aromatic compound wherein the hydrocarbyl substituent is a linear substituent containing 8 to 36 carbon atoms; (2) 0.001 to 25 mole percent based on the total amount of (b)(1) and (b)(2) of a hydrocarbyl- and hydroxy-substituted aromatic compound wherein the hydrocarbyl substituent is a branched substituent containing 8 to 20 carbon atoms; and (3) an amount of an aldehyde, ketone, or reactive equivalent thereof effective to condense (1) and (2) to form the hydrocarbyl- and hydroxy-substituted aromatic condensate. The invention further relates to method of preparing the condensate and its use as an additive in a crude oil, a liquid fuel or an oil of lubricating viscosity.
L'invention concerne une composition contenant: (a) un fluide hydrocarboxylique; et (b) un condensé aromatique hydrocarbyle et hydroxy contenant le produit de réaction de: (1) au moins 75 % en mole sur la base de la quantité totale de (b)(1) et (b)(2) d'un composé aromatique substitué par hydrocarbyle et hydroxy, le substituant hydrocarbyle étant un substituant linéaire contenant 8 à 36 atomes de carbone; (2) 0,001 à 25 % en mole sur la base de la quantité totale de (b)(1) et (b)(2) d'un composé aromatique substitué par hydrocarbyle et hydroxy, le substituant hydrocarbyle étant un substituant ramifié contenant 8 à 20 atomes de carbone ; et (3) une quantité d'aldéhyde, de cétone ou d'un équivalent réactif de ces derniers pour condenser (1) et (2) former le condensé aromatique substitué par hydrocarbyle et hydroxy. L'invention concerne également un procédé de préparation du condensé et son utilisation comme un additif dans une huile brute, un combustible liquide ou une huile de viscosité de lubrification.
