Pitch, vegetable-oil The residue from the distillation of vegetable oil fatty acids or saponified, acidulated vegetable oil fatty acids. Composed primarily of high boiling esters of the fatty acids, neutral materials of vegetable origin with lesser amounts of the free fatty acids.

Tall-oil pitch The residue from the distillation of tall oil. It contains primarily high-boiling esters of fatty acids and rosin. It may also contain neutral materials, free fatty acids and rosin acids.

Pitch, coal tar-petroleum Pitch Residues [The residue from the distillation of a mixture of coal tar and aromatic petroleum streams. A solid with a softening point from 40 °C to 180 °C (140 °F to 356 °F). Composed primarily of a complex combination of three or more membered condensed ring aromatic hydrocarbons.] The residue from the distillation of a mixture of coal tar and aromatic petroleum streams. A solid with a softening point from 40°C to 180°C (104°F to 356°F). Composed primarily of a complex combination of three or more membered condensed ring aromatic hydrocarbons. 648-076-00-X

TALLOW FATTY ACID PITCH)

Residues (coal tar), pitch distn. Pitch Redistillate [Residue from the fractional distillation of pitch distillate boiling in the range of approximately 400 °C to 470 °C (752 °F to 846 °F). Composed primarily of polynuclear aromatic hydrocarbons, and heterocyclic compounds.] Residue from the fractional distillation of pitch distillate boiling in the range of approximately 400°C to 470°C (752°F to 846°F). Composed primarily of polynuclear aromatic hydrocarbons, and heterocyclic compounds. 648-058-00-1

Fatty acids, tall-oil, low-boiling The low boiling fraction obtained by the distillation of tall oil. Contains fatty acids such as palmitic, stearic, oleic and linoleic as well as neutral materials.
