Octadecane

The order of the total area of the microemulsion increasing with different kind of hydrocarbon is n cetane ≈ n tetradecane > n dodecane > n decane > n octadecane > octane .

The dissociated amino acids and KNO3 in the sample amounted to 43.30mg/100g and 3.0 % . Five compounds were isolated and elucidated as octadecane , hexadecylic acid , β - sitosterol , p-coumaric acid and potasium nitrate .

样品中游离氨基酸和KNO3含量分别为42.30mg/100g和3.0%，用柱色谱分离鉴定了十八烷、软脂酸、β-谷甾醇、p-香豆酸和KNO3。

Octadecane has good resolving power for ethylbenzene and p-xylene , but it reverts the elution order of o - and m-xylene and its retarding force for o-xylene is not strong . It has been found that the elution order of solutes varies with the pH value of mobile phase .

十八烷可以很好地分离乙苯和对二甲苯，但邻二甲苯在间二甲苯以后流出，而且它对于邻二甲苯的滞留作用不强。研究表明，不同的pH，溶质的流出次序发生改变。
