Anthracene is a hydrocarbon compound that is composed of three benzene rings fused together. It is a solid, colorless substance that is commonly used in the production of dyes, plastics, and other industrial materials. In this article, we will explore the definition and meaning of anthracene, its origins, and its associations.
Definitions
Anthracene is defined as a tricyclic aromatic hydrocarbon that is composed of three benzene rings fused together. It has the molecular formula C14H10 and a molecular weight of 178.23 g/mol. It is a colorless, crystalline solid that is insoluble in water but soluble in organic solvents such as benzene and toluene.
Origin
The word “anthracene” is derived from the Greek word “anthrax,” which means coal or charcoal. It was first isolated from coal tar in 1832 by the French chemist Auguste Laurent. Since then, it has been widely used in the production of dyes, plastics, and other industrial materials.
Meaning in different dictionaries
According to the Merriam-Webster Dictionary, anthracene is defined as “a crystalline hydrocarbon C14H10 that is obtained from coal tar and is used especially in making dyes.” The Oxford English Dictionary defines it as “a tricyclic aromatic hydrocarbon consisting of three fused benzene rings, obtained from coal tar and used in the manufacture of dyes and other organic compounds.”
Associations
Anthracene is commonly associated with the production of dyes, as it is a key ingredient in the manufacture of many synthetic dyes. It is also used in the production of plastics, rubber, and other industrial materials. In addition, anthracene is a common pollutant in the environment, as it is released into the air and water during the burning of fossil fuels.
Synonyms
Synonyms of anthracene include trinaphthalene, benzanthracene, and 9,10-dihydroanthracene.
Antonyms
There are no antonyms of anthracene, as it is a specific chemical compound with no direct opposite.
The same root words
The root word of anthracene is “anthrax,” which means coal or charcoal. Other words derived from this root include anthracite (a type of coal), anthracosis (a lung disease caused by inhaling coal dust), and anthracnose (a fungal disease that affects plants).
