Alkyl lactates such as 2-ethylhexyl lactate and Et lactate are produced from lactic acid via esterification, and used in the production of plastics, paints, solvents and detergents. In the pursuit of an inexpensive, industry-suitable catalyst for this reaction, the application of protic ionic liquids based on nitrogen base and sulfuric acid is proposed. The ionic liquid was synthesized via a simple reaction of triethylamine and a threefold molar excess of sulfuric acid. Water was added to remove the heat of reaction. Next, the reaction conditions for the model esterification of 2-ethylhexanol with lactic acid without addnl. solvent were optimized. Exceptionally mild conditions, i.e., a twofold molar excess of alc. to lactic acid with the addition of an ionic liquid in a catalytic amount (15 mol%) at 60°C, resulted in high yields of Et and 2-ethylhexyl lactates (96-97%). The driving force of this reaction is the production of a biphasic system with immiscible ester during the reaction. This phenomenon makes it possible to overcome the reaction equilibrium Using an inexpensive ionic liquid, which could be recycled up to five times without diminution in conversion or selectivity, leads to both a greener and a more economically-viable process.
