A method for preparing a water soluble lubricating additive having the generic structural formula:
wherein R₁ is an alkyl, cycloalkyl, aryl, alkaryl or aralkyl group having from 1 to 34 carbon atoms; R₂, R₃ and R₄ are independent alkylene groups having from 2 to 30 carbon atoms; x is either 1 or 2; y is either 0 or 1 when x = 1 and is 0 when x = 2; m is either 0 or 1 and n = 2 to 30 is disclosed, wherein a sulfur-containing alcohol is initially reacted with an organic carboxylic acid to produce an alkylmercapto ester which is then further reacted with an alkylene oxide to produce the lubricating additive. The water-soluble lubricating additives produced in this manner are useful as lubricating additives for water-based fluids used in metalworking operations.
一种制备具有通用结构式的水溶性润滑添加剂的方法:
其中 R₁ 是具有 1 至 34 个碳原子的烷基、环烷基、芳基、烷芳基或芳烷基;R₂、R₃ 和 R₄ 是具有 2 至 30 个碳原子的独立亚烷基;x 是 1 或 2;当 x = 1 时,y 是 0 或 1,当 x = 2 时,y 是 0;m为0或1,n=2至30,其中含硫醇最初与有机羧酸反应生成烷基巯基酯,然后进一步与环氧亚烷基反应生成润滑添加剂。以这种方式生产的水溶性润滑添加剂可用作金属加工作业中使用的水基流体的润滑添加剂。
