Coal Tar
Naphthalene balls, commonly used to combat moths and other pests, are obtained from coal tar. Here is how naphthalene balls are derived from coal tar:
Coal Tar Production:
- Coal tar is a black, viscous liquid obtained during the carbonization of coal to produce coke or coal gas.
- It is a byproduct of the destructive distillation of coal in the absence of air.
Isolation of Naphthalene:
- Coal tar contains various organic compounds, including naphthalene.
- Naphthalene is extracted from coal tar through a process called fractional distillation.
- In this process, coal tar is heated, and different components are separated based on their boiling points.
- Naphthalene has a lower boiling point compared to other components, allowing it to be isolated easily.
Production of Naphthalene Balls:
- Once naphthalene is isolated, it is further processed to form naphthalene balls.
- Naphthalene balls are solid white balls or flakes that are used as a moth repellent due to their strong odor.
- These balls are placed in closets, wardrobes, or other storage areas to protect clothes and fabrics from moth damage.
In conclusion, naphthalene balls are derived from coal tar through the isolation of naphthalene followed by further processing to create the final product used for pest control.
