Naphthalene

NAPHTHALENE

~ also known as Naphthene; 91-20-3; Naphthalin; Camphor tar; Tar camphor; etc. is the simplest polycyclic aromatic hydrocarbon. It is a white crystalline solid and has a strong mothball odor. Naphthalene is gotten from either petroleum distillation or coal tar, and is mainly used to manufacture phthalic anhydride. The global naphthalene market was USD 1.53 Billion in 2017 and is estimated to reach USD 1.85 Billion by 2022, at a CAGR of 3.8% between the years 2017 and 2022.
Chemical structure: Naphthalene is an organic compound with chemical formula C10H8. Naphthalene is an aromatic hydrocarbon and its structure consists of a fused pair of benzene rings.
Properties: Naphthalene is a white crystalline volatile solid and has a strong coal-tar odor...

Solving one of the most intriguing Q’s in Astrochemistry: DIBs

This artist's conception symbolically represents complex organic molecules, known as polycyclic aromatic hydrocarbons, seen in the early universe. These large molecules, comprised of carbon and hydrogen, are among the building blocks of life. NASA's Spitzer Space Telescope is the first telescope to see polycyclic aromatic hydrocarbons so early--10 billion years further back in time than seen previously. Credit: NASA/JPL-Caltech/T.

DIBs  (diffuse interstellar bands) are a collection of about 400 absorption bands that show up in spectra of light that reaches the earth after traversing interstellar medium. Indications exist they may arise from the presence of large hydrocarbon molecules. Recent experiments lend novel credibility to this hypothesis.

Among the hydrocarbons that are p...
