Product application：
1. It is used as an organic reagent, esterifying agent and plasticizer. Since propionic acid can dissolve most organic substances, it is also a commonly used organic solvent.
2. Propionic acid can be used in some acid washing and polishing solutions. It acts as a buffer in weakly acidic solutions (such as galvanizing and chemical nickel plating), as an additive in semi-gloss nickel electrolyte solutions, and can enhance the adhesion of the passivation film in zinc and cadmium passivation solutions. It is also often used to adjust the pH of weakly acidic plating solutions.
3. It is used to synthesize derivatives of propionic acid. Propionic acid can be used to produce propionate salts, such as synthesizing propionate salts of metals like sodium, aluminum, zinc, and cobalt. Propionate salts are widely used as catalysts, auxiliaries in fabric dyeing and leather tanning industries; in addition, sodium propionate, calcium propionate and propionic acid can also be used as food preservatives, and can provide trace elements such as calcium, sodium and potassium in food or feed. For example, adding 0.5% (m/v) calcium propionate to soy sauce can prevent mold growth for 90 days in summer.
