Standard for rating diesel-fuel ignition qualitiesHexadecane serves as a reference for other fuel mixtures and is assigned cetane number of 100; used as shorthand for cetane number, an indicator of the combustion speed of diesel fuel. Hexadecane is used in the preparation of emulsions; also used as a substrate for the production of biosurfactants. n-Hexadecane has been found useful in the identification of the wheat seed protein CM3 as a highly active emulsifier. Superamphiphobicity on polymers can be studied with hexadecane immersion tests. Shape-stabilized phase change material (SSPCM), prepared using hexadecane as a PCM, into xGnP as a supporting material, has been demonstrated to have the potential to be used in developing building materials with improved thermal energy storage charecteristics.
