Naphthalene is not salt, it is an aromatic hydrocarbon with the chemical formula C10H8. It is a white solid with a strong odor and is commonly used as a moth repellent. However, it is also used in the production of other chemicals such as phthalic anhydride and azo dyes. Naphthalene can be obtained from either coal tar or petroleum and is mainly produced in large quantities as a byproduct of the production of coke, which is a fuel obtained from coal.
In addition to its use as a moth repellent, naphthalene has several other applications. It is used in the production of resins, synthetic tanning agents, and lubricants. It is also used as a solvent for certain types of organic compounds and as a fuel for lamps and stoves. Naphthalene is a highly versatile chemical and has a wide range of industrial applications.
However, naphthalene can also be toxic to humans and animals if ingested or inhaled in large amounts. It has been linked to the development of certain types of cancers and can cause damage to the liver and kidneys. As a result, the use of naphthalene is strictly regulated in many countries to ensure that it is used safely and responsibly.
