Abstract: The invention provides lubricating composition comprising: an oil of lubricating viscosity, and an oxyalkylated hydrocarbyl phenol, wherein the oxyalkylated hydrocarbyl phenol is substituted with at least one aliphatic hydrocarbyl group of 40 to 96 carbon atoms, and wherein the oxyalkylated hydrocarbyl phenol is substantially free of aromatic hydrocarbyl groups. The invention further relates to a method of lubricating a mechanical device (such as an internal combustion engine) with the lubricating composition. The invention further relates to the use of the oxyalkylated hydrocarbyl phenol in the lubricating composition to a passenger car internal combustion engine at least one of (i) control of fuel economy, (ii) control of corrosion, (iii) cleanliness, and (iv) control of bore wear.

Abstract: A bridged alkaline earth metal alkylphenate having reduced monomeric alkylphenol is prepared by reacting (a) a 4-alkylphenol, unsubstituted at the ortho positions, (b) an alkaline earth metal oxide or hydroxide, (c) a bridging agent comprising sulfur or a carbonyl compound of 1 to about 6, or to 4 or to 2, carbon atoms, and (d) a 2,6-dialkylphenol. The amount of the 2,6-dialkylphenol is 0.05 to 3 moles per 1 mole of the 4-alkylphenol; if there is a molar excess of the 2,6-dialkylphenol, then the excess is added after initial reaction.

Abstract translation: 通过使（a）在邻位未取代的4-烷基苯酚，（b）碱土金属氧化物或氢氧化物，（c）包含硫或羰基的桥连剂，通过使（a）4-烷基酚反应，制备具有还原单体烷基酚的桥接碱土金属烷基酚盐 1至约6个，或4个或2个碳原子的化合物，和（d）2,6-二烷基苯酚。 2,6-二烷基苯酚的量相对于1摩尔4-烷基酚为0.05〜3摩尔， 如果存在摩尔过量的2,6-二烷基苯酚，则在初始反应后加入过量。
