Characteristic Properties of Cutting Fluid Additives Prepared from Amino Acids and Acid Chlorides

Various adducts were prepared by reactions of amino acids with acid chlorides, and examined for antirust and other characteristic properties. Aqueous solutions of N-acyl leucine and N-acylglutamic acid salts with triethanolamine showed antirust and antiwear properties forward water-based cutting fluids to be quite satisfactory.
