What is Ethyl Propionate?

Ethyl propionate is an ester with a pineapple-like odor, produced through the esterification of propionic acid and ethanol with concentrated sulfuric acid as a catalyst. It has gained significant attention as a key bio-based compound in recent years, with the potential to be used in the synthesis of high-value chemicals, as well as in alternative fuels, food flavors, plasticizers, and other applications. Its use as an alternative fuel offers a promising solution for sustainable development.

Ethyl Propionate Uses

  1. Ethyl propionate is a versatile compound that finds use in a variety of applications. It is commonly used as a top fragrance in daily chemical fragrances, providing a round and ripe aroma, particularly in citrus-cologne type scents. In addition to perfumes and aqueous solutions, it is also utilized in food flavors, adding its distinctive notes to rum, liquor, apple, banana, pear, pineapple, plum, and cream flavors. It is also employed in tobacco flavors.
  2. Furthermore, ethyl propionate serves as a solvent for cellulose esters and ethers, as well as various natural or synthetic resins. It is used as a spice to enhance the flavor of edible products such as apple, banana, plum, pineapple, and butter. Additionally, it is utilized in high-end daily cosmetic fragrances.
  3. Beyond its use in fragrances and flavors, ethyl propionate also has applications in organic synthesis as an intermediate for the production of pyrimethamine, an antimalarial drug primarily used for prophylaxis.

Overall, ethyl propionate is a valuable compound with diverse uses in the fragrance, flavor, and pharmaceutical industries.

Ethyl Propionate Synthesis

The hydrogenation of olefins was carried out using two different methods. In the first method, olefin hydrogenation was performed in a 25 ml two-neck flask connected to a gas buret filled with hydrogen at atmospheric pressure. The catalyst (36 mg) was reduced in a fixed-bed reactor at 200°C or 400°C in a reducing atmosphere of 10 ml/min H2 and 30 ml/min Ar. The flask was purged with hydrogen and the reactants (10 mmol) along with a diluting solvent (2 ml octane) were introduced into the reactor through a septum rubber. The reaction was carried out at 50°C for 1 hour, and after purification, ethyl propionate was obtained with a yield of 78%. The synthesis route is shown in Figure 1.

In the second method, selective hydrogenation of olefins was carried out using BER-Ni2B in methanol. BER (3.33g, 10mmol) was added to Ni(OAc)2. 4H2O (0.25 g, 1 mmol) in MeOH (100 mL) and the mixture was stirred at room temperature to form a black coating of Ni2B. Limonene (1.36 g, 10 mmol) was then added and the mixture was stirred at reflux for 1 hour. GC confirmed the completion of the reaction, and the resin was removed by filtration. The methanol was evaporated under reduced pressure to obtain pure p-menthol. The title compound, ethyl propionate, was obtained in 100% yield. The synthesis route is shown in Figure 1.
