  摘要：

  AbstractTo study the relationship between structure and properties of members of the lipidic thiobis phenol series, as extreme pressure additives in lubricants, a series of homologous compounds has been synthesised by the reaction of alkylphenols with sulphur dichloride. The isomeric n‐nonylphenols have been reacted to form the C9 isomeric 2,2′‐and 4,4′‐thiobisphenols. Longer alkyl side‐chains resulted mainly in the formation of 4,4′‐thiobisphenols and some of the 2,2′ isomer. With short alkyl, particularly t‐alkyl side‐chains, steric hindrance resulted in the 2,2′‐compound. Additive studies have indicated that the longer chain 4,4′ compounds possessed antioxidant properties comparable and superior to former commercial branched chain 2,2′ compounds produced from petrochemical intermediates.

  A magnesium phenate is prepared by a process which comprises reacting (1) magnesium oxide, magnesium hydroxide, magnesium carbonate, magnesium bicarbonate or a magnesium carboxylate with (2) a phenol, a methylene bis-phenol or a sulphurised phenol in the presence of (3) a solvent comprising an organic compound containing one or more alcoholic hydroxyl groups e.g. an alkoxy alcohol and (4) a promoter selected from a ketone, diketone such as α or β diketone, aldehyde or carboxylic acid and (5) optionally a diluent oil. This magnesium phenate may be used as a detergent for a lubricating oil.

  苯酸镁的制备工艺包括：(1) 氧化镁、氢氧化镁、碳酸镁、碳酸氢镁或羧酸镁与(2) 苯酚、亚甲基双酚或硫化苯酚在(3) 溶剂存在下反应，该溶剂包括含有一个或多个醇羟基的有机化合物，例如烷氧基醇和(4) 促进剂，促进剂选自酮、二酮如α或β二酮、醛或羧酸。(4) 一种促进剂，选自酮、二酮如 α 或 β 二酮、醛或羧酸，以及 (5) 可选的稀释剂油。这种苯酸镁可用作润滑油的洗涤剂。
