Isocetane
Encyclopedia
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 (1-methylnaphthalene has cetane number zero) owing to the expense of 1-methylnaphthalene, and difficulty in safe handling.

Cetane number
Cetane number or CN is a measurement of the combustion quality of diesel fuel during compression ignition. It is a significant expression of diesel fuel quality among a number of other measurements that determine overall diesel fuel quality.- Definition :...

1-Methylnaphthalene
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.-External...
