本文着重讨论气相色谱法测定正辛醇氧化油相产物。实验结果表明,使用102担体涂5%聚乙二醇—12000固定液的色谱柱,SP—2305型气相色谱仪,双柱双气路四臂铼钨丝热导池检测器,氢气做载气,在柱温150℃左右,检测室温度200℃,汽化室温度220℃,载气流速65—75ml/min,桥流150mA,柱前压力1.3公斤/厘米~2的操作条件下,对正辛醇氧化产物(油相)进行分析,采用已知物对照法和保留指数法定性,内标法定量,结果令人满意。
This article focuses on the determination of n-octanol oxidation oil phase products by gas chromatography. The experimental results show that using 102 carrier coated with 5% polyethylene glycol-12000 stationary liquid column, SP-2305 gas chromatograph, double-column double gas four-arm rhenium tungsten filament thermal conductivity detector, hydrogen as carrier gas , Under the operating conditions of a column temperature of about 150 ° C, a detection chamber temperature of 200 ° C, a vaporization chamber temperature of 220 ° C, a carrier gas flow rate of 65-75 ml / min, a bridge flow of 150 mA and a column pressure of 1.3 kg / cm 2, Alcohol oxidation products (oil phase) were analyzed by the known control method and the retention index of the qualitative, internal standard method, the results were satisfactory.
