tar base
Quick Summary
Tar bases are organic compounds, specifically alkaline constituents, that are obtained from the distillation of coal tar. These bases are recovered after tar acids, which are phenolic compounds, have been removed from the coal tar distillate.12
Examples of tar bases include aniline, pyridine, and quinoline. Pyridine, a notable example, is a colorless liquid with a strong odor, and its derivatives have pharmaceutical applications. The material left after removing pyridine and other distillates is called pitch, which is used in the aluminum industry.12
