use | used as solvent, gas chromatography comparison sample, standard substance for determination of diesel combustion quality. The decane number of diesel fuel is equal to the percentage of the standard fuel (a mixture of decane and a-methylnaphthalene) with the same combustion quality as the diesel fuel under the specified working conditions. The value of decane is between 40-55. In recent years, the 2,2,4,4,6,6,8,8-heptamethylnonane (HMN) used for synthesis has replaced a-methylnaphthalene as the standard substance, and its decane number is specified as 15. The decadecane number of standard fuel is calculated by the following formula: decadecane = 100 ×(% decadecane) +15 ×(%HMN) such as a mixture containing 35% decadecane and 65% HMN, the base decadecane number is: 100 × 0.35+15 × 0.65=45 used as a solvent, also used in organic synthesis |
Production method | Prepared by 1-hexadecene catalytic chlorination. Add glacial acetic acid to cross iodide decane and zinc powder outside the laboratory, saturate with dry hydrogen chloride, and then heat and react. The generated decane floats on the liquid surface and is distilled under reduced pressure to obtain the finished product. |
