Palmitic acid World War II to produce napalm. The word "napalm" is derived from the words naphthenic acid and palmitic acid. Palmitic acid was discovered by Edmond Frémy in 1840, in saponified palm oil. This remains the primary industrial route for its production, with the triglycerides (fats) in palm oil being hydrolysed by high temperature water (above ), and the resulting mixture fractionally distilled to give the pure product. Palmitic acid is naturally produced by a wide range of other plants and organisms, typically at low levels. It is naturally present in butter, cheese, milk, and meat, as well as cocoa butter,
Diferulic acids Diferulic acids Diferulic acids (also known as dehydrodiferulic acids) are organic compounds that have the general chemical formula CHO, they are formed by dimerisation of ferulic acid. Curcumin and curcuminoids, though having a structure resembling diferulic acids', are not formed that way but through a condensation process. Just as ferulic acid is not the proper IUPAC name, the diferulic acids also tend to have trivial names that are more commonly used than the correct IUPAC name. Diferulic acids are found in plant cell walls, particularly those of grasses. There are currently nine known structures for diferulic acids. They are usually
