摘要
将邻苯二甲酸甲酯化，通过气相色谱法测定邻苯二甲酸二甲酯，从而得到邻苯二甲酸含量．实验确定了最佳酯化时间、最佳色谱分析条件．该方法简便易行，测定结果准确可靠．
In this paper, phthalic acid is methylated. Methyl phthalicate is detected by GC. The content of phthalic acid is obtainable. The best methylate time and GC conditions had been detedmed. The method is simple. The result is satisfactory.
