süsinõli

Süsinõli, also known as coal oil or coal tar oil, is a dark, viscous liquid derived from the distillation of coal. It is a byproduct of the coking process used in the production of coke, a fuel used in steelmaking. The primary components of süsinõli include benzene, toluene, and xylene, which are aromatic hydrocarbons. These components give süsinõli its characteristic smell and color.

Historically, süsinõli was used as a fuel for lighting and heating, particularly in industrial settings. Its high energy content made it a valuable resource before the advent of more efficient and cleaner energy sources. Today, süsinõli is primarily used as a solvent in various industrial applications, such as in the production of paints, varnishes, and adhesives. Its solvent properties are due to the presence of aromatic hydrocarbons, which can dissolve a wide range of organic compounds.

However, the use of süsinõli has declined significantly due to environmental concerns. The aromatic hydrocarbons present in süsinõli are known carcinogens, and its release into the environment can pose health risks. As a result, many countries have implemented regulations to limit or ban the use of süsinõli in certain applications. Despite these concerns, süsinõli remains an important industrial solvent, and its production continues in some regions.
