B. Naraniecki et al., INVESTIGATION OF ALKANOLOAMINE DERIVATIVES OF ORTHOBORIC ACID - FUNCTIONAL ADDITIVES TO METAL-WORKING FLUIDS, Przemysl Chemiczny, 76(7), 1997, pp. 314
Synthesis of mono-, di-, and triethanolamine with orthoboric acid and
chemical structure of products as well as their properties as additive
s in metal working processes are discussed. It has been stated that th
e main and competing chemical products are: alkanolamine salt of boric
acid, alkanolamine ethers and alkanolamine ester of boric acid.
