ANALYTICAL METHOD FOR ELECTROCATALYTIC HYDROGENATION PRODUCTS OF ORGANIC LIQUID HYDRIDES

为建立一种对有机液态氢化物电催化加氢产物进行分析的方法 ,对一系列玻璃管填充柱和毛细管柱进行了筛选 ,考察了柱温、载气流速、进样器温度、检测室温度等条件对色谱柱分离效果的影响 ,建立了苯系电催化加氢产物气相色谱分离方法。其优选条件如下 :色谱柱为 5 0m长的毛细管柱 ,其内径为 0 .2 5mm ,固定液为SP2 10 0 ;柱温为 5 0℃ ,进样器温度为 15 0℃ ,检测室温度为 180℃ ,柱前压为 0 .2MPa(载气流速为 2 5 .1mL/min)。该分析方法具有分析时间短、易控制等特点。

A series of packed and capillary columns were selected to confirm the effects of analytical conditions such as column temperature, flow rate of carrying gas, temperatures in the injector and detector on separation efficiency of GC columns. A proper analytical technique was proposed. This technique has the advantages of short time of operation and easy control. The optimum conditions include capillary column (stationary liquid: SP2100) with a length of 50 m and an inner diameter of 0.25 mm, column temperature of 50 ℃, sample injector temperature of 150 ℃, detector temperature of 180 ℃, and 0.2 MPa column pressure of carrier gas, and 25.1 mLmin flow velocity of carrier gas.
