What is anthracene?
Anthracene is one of a group of chemicals called polycyclic aromatic hydrocarbons, PAH as diminutive. It is an aromatic hydrocarbon of the formula C14H10, colorless solid, at room temperature.
PAHs are often found together in groups of two or more. They can exist in more than 100 different combinations, but the most common are treated as a group of 15.
PAHs are found naturally in the environment, but they can also be made by man.
Anthracene may vary in the appearance of a colorless to pale yellow crystal-like solid.
PAHs are created when products such as coal, oil, gas, and waste are burned, but the burning process is not complete. Like most PAHs, anthracene is used to make dyes, plastics, and pesticides. It was used to make smoke screens and scintillation counter-crystals.
Is anthracene conjugated?
Anthracene is a solid aromatic hydrocarbon (PAH) of the formula C14H10, composed of three fused benzene rings. For an organic compound to be aromatic, it must be cyclic, that means that it needs a planar structure (sp2 / sp carbons), has a conjugated system and must follow (4n + 2) electrons with Huckel’s rule).
Huckel’s Rule is a set of algorithms that combine the number of pi electrons (n) and the physical structure of the ring system to determine whether the molecule is aromatic, antiaromatic, or nonaromatic
Anthracene is formed when we condense three aromatic rings; it is an aromatic hydrocarbon with yellow crystals, density 1.47g / mL, melting point 216 ° C and boiling point 360 ° C. It has a solubility in solvents such as alcohol and ether, but its polarity prevents it to be soluble in water.
It can be used from raw anthracene oils by saline displacement or
still by distillation. It has high applicability as an intermediary in the manufacture of dyes and medicines.
Is anthracene an organic compound?
(Benz)(a)Anthracene, also known as anthrax or anthracene or sodium salt, ion (1-), is a member of the class of compounds known as anthracenes. Anthracenes are organic compounds that contain a system of three linearly fused benzene rings.
Anthracene is a solid polycyclic aromatic hydrocarbon (PAH) of the formula C14H10, consisting of three rings of fused benzene.
Anthracene can be found in sorrel, which makes anthracene a potential biomarker for the consumption of it’s food product. It is a component of coal tar and used in the production of alizarin red dye and other dyes.
Anthracene is colorless but exhibits a blue fluorescence (peak 400-500 nm) under ultraviolet radiation.
Anthracene is formally classified as a potentially toxic, non-carcinogenic and unfounded compound (IARC 3). PAHs are cancerous and have been associated with increased risk of skin, cancer of the respiratory tract, bladder, stomach, and kidneys. They can also cause reproductive effects and depress the immune system.
What are the dangers of anthracene?
Since PAHs exist naturally in the environment and they are man-made, you can be exposed in many ways. You can be exposed to most of them in the environment, in your home and your workplace.
Anthracene was detected in the vapors of vehicle exhaust, coal, tar, and hazardous waste sites.
One of the most common ways of anthracene can enter your body is through breathing contaminated air.
Respiratory Anthracene can irritate the nose, throat, and lungs, causing coughing and wheezing.
If you work in a hazardous waste site where PAHs are discarded, you are likely to breathe anthracene and other PAHs. Exposure can also occur if your skin comes in contact with contaminated soil or products such as heavy oils, coal tar, cover tar or creosote where PAHs were found.
Humans exposed to anthracene experienced headaches, nausea, loss of appetite, inflammation or swelling of the stomach and intestines. Also, your reaction time decreased and they felt weak. Several PAHs have caused tumors in laboratory animals exposed to PAHs through food, through breathing contaminated air and when it was applied to their skin.
Contact with the skin can cause irritation, itching, and burning, which is greatly aggravated by sunlight. Repeated contact can cause thickening of the skin and changes in pigments
Once in your body, PAHs can spread and reach adipose tissues. The target organs are the skin, blood, stomach and intestines and the lymphatic system. However, in just a few days, the PAHs leave your body through urine and feces.
