S. Watanabe et al., CHARACTERISTIC PROPERTIES OF CUTTING FLUID ADDITIVES DERIVED FROM HALF ESTERS OF DIMER ACIDS, Journal of the American Oil Chemists' Society, 73(6), 1996, pp. 807-809
A number of half esters were prepared from the reaction of alcohols wi
th dimer acids and screened for anti-rust properties and antimicrobial
activity in spent coolants of water-based cutting fluids. Aqueous sol
utions of triethanolamine salts with lower-alcohol half esters of dime
r acid showed good anti-rust properties for water-based cutting fluids
