A method was introduced for quantitative analysis of α-pinene,β-pinene,p-cymene and longifolene by 1102-Gas Chromatograph with the n-dodecane as internal standard. 选用正十二烷为内标物,采用内标法对α-蒎烯、β-蒎烯、对伞花烃和长叶烯进行了定量分析。
Dodecane (also known as dihexyl, bihexyl, adakane 12 or duodecane) is a liquid alkane hydrocarbon with the chemical formula CH3(CH2)10CH3 (or C12H26), an oily liquid of the paraffin series. It has 355 isomers.
It is used as a solvent, distillation chaser, and scintillator component. It is used as a diluent for tributyl phosphate (TBP) in reprocessing plants.
