1-Methylnaphthalene is a polycyclic aromatic hydrocarbon (PAH). It has a cetane number of zero, and was previously used as the lower reference for cetane number. However, due to the expense and handling difficulty of 1-Methylnaphthalene, it was replaced in this capacity by isocetane, with a CN of 15. [2 ]
On February 22, 2014,
NASA announced a greatly upgraded database [3 ] for detecting and monitoring PAHs, including 1-Methylnaphthalene, in the [4 ] universe. According to NASA scientists, over 20% of the carbon in the universe may be associated with PAHs, possible starting materials for the formation of life. PAHs seem to have been formed shortly after the [3 ] Big Bang, are abundant in the universe, [5 ] [6 ] and are associated with [7 ] new stars and exoplanets. [3 ]
