| Abstract: | A variety of alkoxyaromatic carboxylic acids and acyloxyaromatic carboxylic acids were prepared from various hydroxyaromatic carboxylic acids, and screened for anti-rust properties, lubrication properties and antimicrobial activity in spent coolants of water-soluble cutting fluids. The triethanolamine salt of alkoxydiphenyl carboxylic acids showed good anti-rust activity and lubrication properties. The triethanolamine salts ofp-alkoxyphenyl propionic acid showed good antimicrobial activity together with good anti-rust properties and lubrication properties. |
