    摘要： 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 hydro-carbyl- 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.
