BASF: Fifty years of Propionic Acid Manufacturing
A rather acidic success story started at BASF 50 years ago: in the summer of 1960, the company brought on stream the first large-scale manufacturing plant for propionic acid at its integrated Ludwigshafen Verbund site in Germany. The inauguration of another facility that produces this carboxylic acid followed at the Nanjing site in China in 2005. Having expanded the annual capacity at these sites in 2009, which brought its total annual capacity to 149,000 t, BASF SE, Ludwigshafen, Germany, is now one of the world’s major propionic acid manufacturers. This organic acid, which also occurs naturally, is valued as a preservative for feedgrain and as a building block for synthesis, for example in the production of pharmaceuticals, crop protection products and plastics. The company has to date produced about 2.4 million t of propionic acid.
