Preparation of ester of alkenylsuccinic acid and oxyethylated alkylphenol
This paper investigates the esterification of alkenylsuccinic acid (ASA) with an oxyethylated alkyphenol (OEP) and investigates the protective efficiency of the ester products. It is shown that the physicochemical properties and the protective efficiency of the ester products are influenced by the conditions of its synthesis. The ester obtained with a ratio of c /SUB ASA/ : c /SUB OEP/ = 1:1 has the best protective properties, thermal stability, and oil solubility. This is apparently related to the fact that the final product does not contain any alkylphenol, which is less thermally stable and is more deficient in terms of thin-film protective properties. The oxyethylated ester of alkenylsuccinic acid is being used as one of the components of highly effective ashless corrosion inhibitors; and as part of these corrosion inhibitors, it is used in operational/preservative oils for various engines, gear, and transmission components.
