Its pricing is influenced by crude oil prices (for synthetic ethanol), agricultural commodity prices (for bio-based ethanol like corn, sugarcane), and demand from industries like fuel blending and industrial solvents. Industrial procurement of high-purity ethanol is essential, and its cost contributes significantly to operating expenses.
• Carbon Monoxide (CO): A crucial reactant in both the Larson and Reppe processes. Carbon monoxide is primarily obtained from steam methane reforming, partial oxidation of hydrocarbons, or coal gasification. Its availability and pricing are influenced by natural gas prices and demand from industries like acetic acid production, polycarbonates, and chemical synthesis. Industrial procurement for large volumes of high-purity carbon monoxide is essential for large-scale production.
• Ethylene (C2H4): It is also used as a starting material in the Reppe Process. Ethylene is a foundational petrochemical, produced by steam cracking of naphtha or ethane. Its availability and pricing are highly influenced by crude oil and natural gas prices. Industrial procurement for high-purity ethylene is essential for large-scale propionic acid production.
• Boron Trifluoride (BF3): It is used as a catalyst in the Larson Process (often as a complex, e.g., with methanol or diethyl ether). Boron trifluoride is a specialised chemical, produced from boric acid and hydrogen fluoride. Its pricing varies significantly based on purity and form (gas, liquid complex). The cost of the catalyst, including initial fill and regeneration/replacement, contributes to both CAPEX and OPEX.
• Water (H2O): A reactant in the Reppe process. While generally inexpensive, large volumes contribute to overall operating expenses, especially for high-purity requirements.

Production by the Larson Process (Hydrocarboxylation of Ethanol)

The feedstock for this method includes ethanol (CH3CH2OH) and carbon monoxide (CO). This method involves the hydrocarboxylation of ethanol. The process begins with the reaction of ethanol and carbon monoxide in the presence of a specific catalyst system, mainly boron trifluoride (BF3) complexed with phosphoric acid or another co-catalyst. The reaction takes place at elevated temperatures of around 200−250 degree Celsius and high pressures (e.g., 20-60 MPa) in a specialised reactor. Under these conditions, the reaction results in the formation of propionic acid as the final product. After the reaction, the crude product mixture is processed to recover the catalyst (often recycled) and separate propionic acid from unreacted raw materials and any byproducts through distillation.
 

Production by Reppe Process (Hydrocarboxylation of Ethylene)

The feedstock for this method includes ethylene (C2H4), carbon monoxide (CO), and water (H2O). This method is primarily used for the large-scale production of propionic acid and involves the hydrocarboxylation of ethylene. The synthesis starts with a chemical reaction between ethylene, carbon monoxide, and water at high temperatures of 150−250 degree Celsius and high pressures. The reaction proceeds in the presence of a transition metal catalyst, commonly a nickel carbonyl, cobalt, or rhodium complex, which produces propionic acid. After the reaction, the crude propionic acid is separated from the catalyst and byproducts through distillation and other purification steps to obtain high-purity propionic acid as the final product.
