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.
The sarcosine head group of the long-chain amphiphilic N-acylamino acid is responsible for the formation of chelate-like structures in the adsorption on polar and charged surfaces, e.g. on metals. [6] The molecules form oriented monomolecular films that protect the metal surface from corrosive attack. [4]
