Organic Solvents Organic Intermediate N-HEXADECANE-D34 CAS 544-76-3 Gas Chromatography Comparison Samples

Introduction:

Colorless liquid. Melting point 18.17℃, boiling point 287℃, 149℃ (1.33kPa); relative density 0.77331 (20/4℃), refractive index 1.4335. Flash point 135℃. Miscible with ethe and petroleum ethe, slightly soluble in hot ethanol, insoluble in water.

Uses:

Used as solvent, gas chromatography comparison sample, and standard substance for determining diesel combustion quality. The cetane number of diesel is equal to the volume percentage of decadecane contained in the standard fuel (a mixture of hexadecane and a-methylnaphthalene) when the combustion quality is the same as that of the diesel being evaluated under specified working conditions. The cetane number is between 40-55. In recent years, the synthetic 2,2,4,4,6,6,8,8-heptamethylnonane (HMN) has been used instead of a-methylnaphthalene as the standard substance, and its cetane number is specified to be 15. The cetane number of the standard fuel is calculated using the following formula: Cetane = 100× (% hexadecane) + 15× (% HMN). For example, a mixture containing 35% hexadecane and 65% HMN has a cetane number of: 100×0.35+15×0.65=45
