1-Methylnaphthalene
Encyclopedia
1-Methylnaphthalene is an aromatic hydrocarbon
. 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.
Hydrocarbon
In organic chemistry, a hydrocarbon is an organic compound consisting entirely of hydrogen and carbon. Hydrocarbons from which one hydrogen atom has been removed are functional groups, called hydrocarbyls....

Isocetane
Isocetane is a highly branched alkane used as a reference in determining the cetane number of diesel. It is given a cetane number of 15. Isocetane replaced 1-methylnaphthalene as the lower reference for cetane number owing to the expense of 1-methylnaphthalene, and difficulty in safe handling....
