摘要
介绍对羟基苯甲醛的气相色谱分析方法，以ＯＶ１７为固定相，氢火焰离子化检测器，邻苯二甲酸二乙酯为内标物，用无水乙醇作溶剂，采用内标法测定对羟基苯甲醛的含量．实验结果表明，该方法准确可靠，限制条件少，可用于对羟基苯甲醛产品的定量分析．用此方法测得对羟基苯甲醛的相对重量校正因子为１１９，标准偏差为２１２％
A analysis procedure of \%p\%hydroxybenzaldehyde by gas chromatography was established.Contents of the title compound was determined using OV17 as stationary phase,FID as detector,diethyl phthalate as inside standard compound,and anhydrous alcohol as solvent.Experimental results showed that this method is accurate,easy to operate and can be applied to quantitative analysis.The relative weight correction factor of \%p\%hydroxybenzaldehyde to diethyl phthalate is 1.19,and its standard deviation is 2.12 %.
