Decanoic acid Uses

 Decanoic acid (CAS NO.334-48-5) is used in organic synthesis and industrially in the manufacture of perfumes, lubricants, greases, rubber, dyes, plastics, food additives and pharmaceuticals.

Decanoic acid Production

Production of Decanoic acid (CAS NO.334-48-5):
 Capric acid occurs naturally in coconut oil and palm kernel oil, as well as in the milk of various mammals and to a lesser extent in other animal fats. Decanoic acid can be prepared from oxidation of primary alcohol decanol, by using chromium trioxide (CrO3) oxidant under acidic conditions in an acetone solvent. This will give decanoic acid in up to 93% yield.
