Propionic Acid Production from Propionaldehyde

By Intratec Solutions |

This column is based on “Propionic Acid Production from Propionaldehyde – Cost Analysis,” a report published by Intratec. It can be found at: www.intratec.us/analysis/propionic-acid-production-cost. Propionic acid (also known as propanoic acid) is a carboxylic acid commonly found in nature, mainly in its ester form in some essential oils. This fatty acid is also formed in a number of enzymatic and fermentation processes. Widely used in the production of cellulose esters, plastic dispersions and herbicides, propionic acid has gained importance in recent years for applications related to preservation of forage-cereal crops and animal feeds. The uses and applications of propionic acid vary according to the product grade. The main form of propionic acid is one with 99.5 wt.% minimum purity. Most industrially produced propionic acid is used as a preservative in stored animal feed and grain. Examples of its agricultural applications include its uses as the following: an antibacterial additive (for livestock and poultry drinking water); a surface sanitizer (in storage areas for silage and grain); a poultry-litter additive; and for use with high-moisture grains in indoor storage. To a lesser extent, propionic acid is also used as a…
