1-Methylnaphthalene is an organic compound with the formula C11H10. It is a colorless liquid. It is isomeric with 2-methylnaphthalene. It is generally obtained as a minor component of coal tar.
==Reference fuel== 1-Methylnaphthalene defines the lower (zero) reference point of cetane number, a measure of diesel fuel ignition quality, as it has a long ignition delay (poor ignition qualities). In contrast, cetane, with its short ignition delay, defines the upper reference point at 100. In testing, isocetane (2,2,4,4,6,8,8-heptamethylnonane or HMN) replaced 1-methylnaphthalene as the low cetane number reference fuel in 1962 for reasons of better oxidation stability and ease of use in the reference engine. The scale is unchanged, as isocetane's cetane number is measured at 15, referenced to 1-methylnaphthalene and cetane.
