摘要
提出了用气相色谱分析法同时检测氧化羰基化法合成碳酸二苯酯(DPC)反应液中的DPC和苯酚含量的新方法。用外标法测定苯酚含量,以苯酚为内标物,测定DPC的含量。这种检测方法克服了由于DPC响应值低,进样给DPC准确测量带来的误差。这种内外标结合法为今后反应液准确测定提供了一种简便易行的方法。
The new method for determining the reaction mixture of diphenyl carbonate （ DPC ） and phenol through oxidative carbonylation by gas chromatographic is presented. The quantitative determination of phenol is carried out with GC by external standard method.. The quantitative determination of DPC phenol as internal material. The method avoids the error of the injection, responding corrector. It indicates that this method has high accuracy and is obtaited by internal standard method with especially for the diphenyl carbonate with low stability and can be used in other determination of organic reaction mixture.
