Tall oil fatty acid (TOFA), with the CAS number 61790 - 12 - 3, is a versatile and cost - effective unsaturated fatty acid mixture mainly composed of oleic acid, linoleic acid, and their isomers, along with small amounts of rosin acid and unsaponifiable matter. Derived as a by - product from the sulfate pulping process in the paper industry, TOFA has found its way into a wide array of industrial applications.
Can be used as synthetic ester emulsifiers and surface treatment agents, can be used as metal surface cleaners, as excellent emulsifiers in metalworking oils and as raw materials for ester oils, also directly used as cleaners after metal processing, providing good lubricity and rust prevention. Additionally, it can be used as raw materials for dimer acids, paints, metalworking fluids, and as flotation agents among other applications.
Oleic acid is an organic chemical raw material, which can be produced by epoxidation Epoxy oleate, used as plastic plasticizer, azelaic acid can be produced by oxidation, which is the raw material of polyamide resin. In addition, oleic acid can also be used as pesticide emulsifier, printing and dyeing auxiliaries, industrial solvents, metal mineral flotation agents, mold release agents, etc., and can also be used as raw materials for the production of carbon paper, round bead crude oil and typing wax paper. Various oleate products are also important derivatives of oleic acid. As a chemical reagent, it is used as a chromatographic comparison sample and for biochemical research to detect calcium, copper, magnesium, sulfur and other elements.
