NAPHTHALENES Meaning and
Definition
-
Naphthalenes are a class of organic compounds that belong to the aromatic hydrocarbon group. They are formed by two benzene rings fused together, resulting in a polycyclic structure. The chemical formula for naphthalene is C10H8, and it has a molecular weight of 128.17 grams per mole.
Naphthalenes are commonly found in petroleum and coal tar, and they occur naturally in crude oil and some minerals. They can also be produced through various industrial processes, such as the distillation of coal tar or the catalytic reforming of petroleum. Naphthalenes are known for their strong and distinct aroma, often described as mothball-like.
These compounds have a wide range of applications in industry and everyday life. One of the most significant uses of naphthalenes is as a starting material for the production of various chemicals, including dyes, pharmaceuticals, and agrochemicals. They are also employed as solvents, cleaning agents, and as additives in the production of rubber and plastics.
Naphthalenes possess some toxic properties and can be harmful if inhaled or ingested in high quantities. Prolonged exposure to naphthalene vapors or dust may lead to irritation of the respiratory system, skin, and eyes. Additionally, naphthalenes are classified as potential carcinogens by several regulatory bodies, necessitating precautions in their handling and use.
In summary, naphthalenes are a class of aromatic hydrocarbons that consist of two fused benzene rings. They are used as starting materials in the production of various chemicals and find applications in multiple industries. However, careful handling and exposure control are necessary due to their toxic and potentially carcinogenic nature.
Etymology of NAPHTHALENES
The word "naphthalenes" is derived from the term "naphthalene". The term "naphthalene" itself is derived from the word "naphtha", which refers to a flammable liquid hydrocarbon mixture. The word "naphtha" can be traced back to the Greek word "naphthe", meaning "bitumen" or "tar". Thus, "naphthalene" originally referred to a white crystalline substance obtained from the distillation of coal tar. The plural form "naphthalenes" simply indicates multiple units of the compound.
