What is Tall Oil Fatty Acid?
Definition
Crude tall oil (CTO) is not a fatty oil. However, it is actually a mixture of five components with different boiling points, which are split by fractionation into heads (which boils first), then ‘tall oil fatty acids’ (TOFAs), distilled tall oil (DTO, a mixture of fatty and rosin acids), ‘tall oil rosin’ (TOR, a mixture of eight closely related rosin acids, i.e., abietic, neoabietic, palustric, levopimaric, dehydroabietic, pimaric, sandaracopimaric, and isopimaric acid), and pitch (the unsaponifiable residue). TOFA is mainly oleic acid. Furthermore, TOFAs contain unusual isomers, such as octadecadienoic acids with double bonds in the 5,9- and 5,12-positions. Important applications of TOFA are the manufacture of alkyd resins and dimer acids[1].
What are the applications of Application
Tall oil fatty acids are a by-product of the wood pulp industry when pine wood chips are digested and chemically treated. It is produced mainly in North America and Scandinavia, with the two oils differing somewhat in composition due to the tree species used. Either oil, however, is used to produce dimer acids, alkyols and coatings, detergents, and lubricants. There are future possibilities for use as solvents, inks, and biodiesel production.
