Abstract: The disclosed technology provides a lubricating composition comprising an oil of lubricating viscosity and 0.01 wt % to 10 wt % of an oxyalkylated aromatic polyol compound, wherein the aromatic compound has at least one alkoxy group represented by −OR1 group, R1 is hydroxyalkyl, or a (poly)ether group, and either: at least one hydroxyl group, or at least one alkoxy group represented by —OR1 group, where R1 is alkyl, or a (poly)ether group, or at least one oxyalkyl group represented by —OR1, where R1 is hydroxyalkyl or a (poly)ether group. The disclosed technology further relates to a method of lubricating a mechanical device (such as an internal combustion engine) with the lubricating composition. The disclosed technology further relates to the use of the oxyalkylated aromatic polyol compound 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 sulfurized alkaline earth metal (e.g., calcium) dodecylphenate is prepared by reacting (i) dodecylphenol with (ii) calcium hydroxide or calcium oxide in an amount of about 0.3 to about 0.7 moles per mole of dodecylphenol charged and (iii) an alkylene glycol in an amount of about 0.13 to about 0.6 moles per mole of dodecylphenol charged; and reacting the product of the first step with sulfur in an amount of about 1.6 to about 3 moles per mole of dodecylphenol charged; and thereafter optionally reacting the product with additional calcium hydroxide or calcium oxide and with carbon dioxide so as to form an overbased phenate. The product thus prepared has reduced levels of monomeric dodecylphenol.

Abstract translation: 通过使（i）十二烷基苯酚与（ii）氢氧化钙或氧化钙以每摩尔十二烷基酚加入量为约0.3至约0.7摩尔的量和（iii）亚烷基二醇（ⅰ）来制备硫酸化的碱土金属（例如，钙）十二烷基苯酚 每摩尔十二烷基酚加入约0.13至约0.6摩尔的量; 并使第一步产物与约1.6至约3摩尔/摩尔十二烷基酚加入量的硫反应; 然后任选地使产物与另外的氢氧化钙或氧化钙和二氧化碳反应，以形成高碱性酚盐。 由此制备的产物具有降低的单体十二烷基酚水平。
