Usage

Description

Tall oil is a versatile byproduct of the paper industry, derived from the wood of pine and other coniferous trees. It is a complex mixture of various organic compounds, including fatty acids, resin acids, and terpenes, which contribute to its wide range of applications across different industries.

Uses

Used in Paint and Coating Industry:
Tall oil is used as a paint vehicle for its ability to improve the flow and leveling properties of paint, resulting in a smoother and more uniform finish.
Used in Chemical Industry:
Tall oil serves as a source of rosin and alkyd resins, which are essential components in the production of various chemical products.
Used in Soap and Detergent Industry:
Tall oil is used as a raw material for the production of soaps, cutting oils, and emulsifiers, due to its surfactant properties and ability to create stable emulsions.
Used in Mining Industry:
Tall oil is used as a drier and flotation agent, enhancing the efficiency of mineral processing and extraction.
Used in Oil and Gas Industry:
Tall oil is used in oil-well drilling muds, core oils, and lubricants, providing essential functions such as reducing friction, cooling, and protecting drilling equipment.
Used in Construction Industry:
Tall oil is used in the production of asphalt derivatives, improving the performance and durability of asphalt-based materials.
Used in Rubber Industry:
Tall oil is used in rubber reclaiming, a process that involves the recovery and reuse of rubber materials, contributing to more sustainable rubber production.
Used in Pharmaceutical Industry:
Tall oil is used in the synthesis of cortisone and sex hormones, playing a crucial role in the production of essential medications.
Used in Specialty Chemicals:
Tall oil serves as a chemical intermediate in the production of various specialty chemicals, such as tall oil fatty acids, tall oil rosin, and tall oil pitch, which are used in a wide range of applications, including adhesives, coatings, inks, and more.

Origin of Name

Tall is the Swedish word for pine, and the term tall oil is an American adaptation of tallolja, a Swedish product name associated with the kraft pulping process and with products from the fractional distillation of crude tall oil.Abbreviations of basic tall oil names and common analyses often used in publications and reports are: Crude tall oil (CTO); Tall oil fatty acids (TOFA); Tall oil rosin (TOR); Distilled tall oil (DTO); Tall oil pitch (TOP); and Heads, light ends (H).

Production Methods

Pine wood contains an extractable fraction, ≈3%, consisting of free and combined fatty and rosin acids and nonacidic compounds (tall oil components). In the alkaline pulping process the tall oil components are saponified into a soapy material that, when acidulated, gives a mixture of free rosin and fatty acids and neutral components—crude tall oil (CTO). CTO is refined mainly by vacuum distillation processes to separate the various compounds almost completely into rosin and fatty acid fractions. The rosin part of CTO is a complex mixture of rosin acids, a threering fused system with the empirical formula C20H30O2. The tall oil fatty acids, primarily C18 types, are similar in composition to those derived from soybean oil. The neutral constituents of tall oil—predominantly esters, sterols, and hydrocarbons—are generally regarded as troublesome “impurities” that impair its utilization and distillation.
