3Glass capillary gas chromatography is used in the analysis of n-paraffin distribution of the diesel,and according to the results of the cold filter plugging point test ,it is conclude that the impressibility of DFI to fuel is not only connected with the alkyl side chain and the polarity group of medicine oneself ,but also the n -paraffin distribution of the diesel ,the component ,technology and directions for producing of fuel and so on.

该方法具有合成线路短、产率高、成本低的特点；(3)通过使用毛细管气相色谱法测定柴油中直链烷烃的组成与含量，及柴油冷滤点(Cold filter plugging point 简称CFPP)的测定得出结论，DFI 对柴油的感受性不仅与药剂本身的烷基侧链、极性基团有关，也与柴油的直链烷烃的含量、馏分组成、加工工艺等有关。

This split should be made by inserting the point of the knife under the hide with the lade turned up.

将刀尖插入皮下，用刀锋划开牛皮。第一步就要将原油分割成更易处理的馏分。

Mono /di hexyl methylnaphthalene could be obtained from β methylnaphthaleneand n bromohexane proceeding condensation catalyzed by anhydrous aluminium chloride.
