Tall Oil, also known as liquid rosin, is a resinous yellow-black oily liquid
composed of a mixture of rosins, fatty acids, sterols, high-molecular alcohols,
and other alkyl chain materials; obtained as a byproduct in the treatment of
pine pulp. The crude tall oil is distilled into tall oil rosin (having the rosin
content of 10 - 35%), further refinery gives to tall oil fatty acid (the rosin
content of 1 - 10%). Pitch is used as a emulsifier of asphalt and as a binder of
cement and adhesive. Rosin is used as a raw material for rubbers, paper size,
inks, and adhesives. It is used as an emulsifier in SBR polymerization for
fluidity increasing. It is used in ore flotation, corrosion inhibitors and crude
dimers applications. Tall oil fatty acid (TOFA) is a low cost unsaturated fatty
acid (oleic acid) and is a source of low boiling point fatty acids.
It is an alternative to tallow fatty acid in soap applications.
It is used as a dryer in varnishes and paints. It is used in paper sizes, inks,
adhesives, alkyd resins, linoleum, oilcloth, cleaners, lubricants, dimer acids,
surfactants, oil field chemicals, greases and ore flotation reagents.
